Why do we need this WebSockets2_Generic library

Features

Many Web services require WebSockets library, which is so far written only for ESP8266/ESP32 boards. The ESP boards so far rely on the Markus Sattler's WebSockets Library to connect to Alexa via Sinric or SinricPro skills.

This WebSockets2_Generic library is based on and modified from Gil Maimon's ArduinoWebSockets Library to provide support to many more boards, such as WT32_ETH01 (ESP32 + LAN8720), Arduino SAMD21, Adafruit SAMD21/SAMD51, Seeeduino SAMD21/SAMD51, nRF52, STM32F/L/H/G/WB/MP1, Teensy, SAM DUE, Portenta_H7, etc. and enable those boards to use WebSockets services, including voice-controlled Alexa along with Blynk. Those supported boards can also run WebSockets Server. The WebSockets can be used with ESP’s WiFi, WiFiNINA, WiFi101, W5x00/ENC28J60/LAN8742A Ethernet, Teensy 4.1 NativeEthernet/QNEthernet, ESP8266/ESP32-AT modules/shields, Portenta_H7 WiFi/Ethernet, RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, using WiFiNINA.

Please see the TinyWebsockets wiki for roughly-accurate information about the API not covered here.

  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/system/STM32F7xx/stm32f7xx_hal_conf_default.h

7.2 For STM32 boards to use Serial1

To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/2.3.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

Supposing the STM32 stm32 core version is 2.3.0. These files must be copied into the directory:

  • ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz, these files must be copied into the corresponding directory:

  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h
  • ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h

8. For RP2040-based boards using Earle Philhower arduino-pico core

8.1 To use BOARD_NAME

To be able to automatically detect and display BOARD_NAME on RP2040-based boards (RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, etc) boards, you have to copy the file RP2040 platform.txt into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).

Supposing the rp2040 core version is 1.4.0. This file must be copied into the directory:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/platform.txt

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied into the directory:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/platform.txt

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add -DBOARD_NAME="{build.board}" #136.

8.2 To avoid compile error relating to microsecondsToClockCycles

Some libraries, such as Adafruit DHT-sensor-library, require the definition of microsecondsToClockCycles(). To be able to compile and run on RP2040-based boards, you have to copy the files in RP2040 Arduino.h into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).

Supposing the rp2040 core version is 1.4.0. This file must be copied to replace:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/cores/rp2040/Arduino.h

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz This file must be copied to replace:

  • ~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/cores/rp2040/Arduino.h

With core after v1.5.0, this step is not necessary anymore thanks to the PR Add defs for compatibility #142.

9. For Portenta_H7 boards using Arduino IDE in Linux

To be able to upload firmware to Portenta_H7 using Arduino IDE in Linux (Ubuntu, etc.), you have to copy the file portenta_post_install.sh into mbed_portenta directory (~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh).

Then run the following command using sudo

$ cd ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1
$ chmod 755 portenta_post_install.sh

Libraries' Patches

1. For application requiring 2K+ HTML page

If your application requires 2K+ HTML page, the current Ethernet library must be modified if you are using W5200/W5500 Ethernet shields. W5100 is not supported for 2K+ buffer. If you use boards requiring different CS/SS pin for W5x00 Ethernet shield, for example ESP32, ESP8266, nRF52, etc., you also have to modify the following libraries to be able to specify the CS/SS pin correctly.

2. For Ethernet library

To fix Ethernet library, just copy these following files into the Ethernet library directory to overwrite the old files:

You can also use the forked and modified library at Patched Ethernet

  • From Ethernet.h to Ethernet_ESP8266.h


Note for Platform IO using ESP32 LittleFS

Necessary only for esp32 core v1.0.6-

From esp32 core v1.0.6+, LittleFS_esp32 v1.0.6 has been included and this step is not necessary anymore.

In Platform IO, to fix the error when using LittleFS_esp32 v1.0 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

to

#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

It's advisable to use the latest LittleFS_esp32 v1.0.5+ to avoid the issue.

Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'



HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)

Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.

1. ESP32 has 2 ADCs, named ADC1 and ADC2

2. ESP32 ADCs functions

  • ADC1 controls ADC function for pins GPIO32-GPIO39
  • ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27

3.. ESP32 WiFi uses ADC2 for WiFi functions

Look in file adc_common.c

In ADC2, there're two locks used for different cases:

  1. lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.

  2. lock shared between tasks: when several tasks sharing the ADC2, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon, we use a spinlock to stand there waiting to do conversions one by one.

adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.

  • In order to use ADC2 for other functions, we have to acquire complicated firmware locks and very difficult to do
  • So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
  • Use ADC1, and pins GPIO32-GPIO39
  • If somehow it's a must to use those pins serviced by ADC2 (GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).

Important Notes

  1. Code is restructured to provide flexibility to make it easy to support many more WiFi/Ethernet modules/shields in the future. Please delete the *.cpp files, replaced by *.hpp files, in the src directory, if *.cpp files still exist after installing new version.

  2. For Adafruit nRF52, use the SPI's pin as follows:

  • SS/CS = 10
  • SPI_MOSI = MO(SI)
  • SPI_MISO = MI(SO)
  • SPI_SCK = SCK
  1. For Adafruit SAMD21/SAMD51, use the SPI's CS/SS pin as follows:
  • Itsy-Bitsy M0/M4, Feather M0 (Express), Hallowing M0 Express, Zero, Metro M0 => use CS = 16 = pin A2
  • Feather M4 (SAMD51) => use SS/CS = 9
  • Grand Central M4 => use SS/CS = 53
  • Hallowing M4 => use SS/CS = 10
  • Metro M4 AirLift => use SS/CS = 36

To know the default CS/SS pins of not listed boards, check the related variant.h files in

~/.arduino15/packages/adafruit/hardware/samd/x.y.zz/variants/board_name/variant.h

  1. For Arduino SAM DUE, use the SPI's pin as follows:

  1. For RP2040 using Arduino mbed_rp2040 core, use the SPI's pin as follows:
  • SS/CS = 5
  • SPI_MOSI = 3
  • SPI_MISO = 4
  • SPI_SCK = 2
  1. For RP2040 using Earle Philhower's arduino-pico core, use the SPI's pin as follows:
  • SS/CS = 17
  • SPI_MOSI = 19
  • SPI_MISO = 16
  • SPI_SCK = 18


Basic Usage

Client

Creating a client and connecting to a server:

WebsocketsClient client;
client.connect("ws://your-server-ip:port/uri");

Sending a message:

client.send("Hello Server!");

Waiting for messages:

  1. Using Lambda function
// run callback when messages are received
client.onMessage([&](WebsocketsMessage message) 
{
  Serial.print("Got Message: ");
  Serial.println(message.data());
});
  1. Using normal callback function
// run callback when events are occurring
  client.onMessage(onMessageCallback);

and

void onMessageCallback(WebsocketsMessage message)
{
  //Doing something with received String message.data() type
  
  Serial.print("Got Message: ");
  Serial.println(message.data());
}

HOWTO keep receiving messages:

void loop() 
{
  client.poll();
}

Server

Creating a server and listening for connections:

WebsocketsServer server;
server.listen(8080);

Accepting connections:

WebsocketsClient client = server.accept();

// handle client as described before :)
// run callback when messages are received
client.onMessage([&](WebsocketsMessage message) 
{
  Serial.print("Got Message: ");
  Serial.println(message.data());
});

Reading WebSockets Client messages using non-blocking mode (new from v1.0.6):

Using this new feature to enable doing other tasks in the loop(), such as WebServer, control tasks, etc. Server, using library version before v1.0.6, can only read Client messages in blocking mode. Therefore, the WebSocket Server can't hang, waiting for Client, and block all other tasks from running.

  // You can do some other tasks here, such as WebServer, controlling tasks, etc.
  
  WebsocketsClient client = SocketsServer.accept();

  if (client.available())
  {
    WebsocketsMessage msg = client.readNonBlocking();

    // log
    Serial.print("Got Message: ");
    Serial.println(msg.data());

    // return echo
    client.send("Echo: " + msg.data());

    // close the connection
    client.close();
  }

Please test using one of these following new examples with v1.0.6 and v1.0.5- to see the blocking effects. Please remember to change in loop() from

WebsocketsMessage msg = client.readNonBlocking();

to

WebsocketsMessage msg = client.readBlocking();

as client.readNonBlocking() is a new function in v1.0.6+.

Binary Data

For binary data it is recommended to use msg.rawData() which returns a std::string, or msg.c_str() which returns a const char*. The reason is that msg.data() returns an Arduino String, which is great for Serial printing and very basic memory handling but bad for most binary usages.

See issue #32 for further information.

SSL and WSS Support

No matter what board you are using, in order to use WSS (websockets over SSL) you need to use

client.connect("wss://your-secured-server-ip:port/uri");

The next sections describe board-specific code for using WSS with the library.

ESP8266

With the esp8266 there are multiple ways for using WSS. By default, ArduinoWebsockets does not validate the certificate chain. This can be set explicitly using:

client.setInsecure();

You can also use a SSL Fingerprint to validate the SSL connection, for example:

// To update SHA1 fingerprint, use Google Chrome to connect to https://www.websocket.org/echo.html 
// Then "View Site Information" => "Certificate Viewer" => Copy SHA1 fingerprint
// KH, This SHA1 fingerprint was updated 15.04.2021, 
// Issued on Mar 15th 2021, expired on June 13th 2021
const char echo_org_ssl_fingerprint[] PROGMEM   = "34 A2 66 08 A1 4D 1E 83 1A 0E 49 3C 4A 84 45 9E 4A 0D 08 FE";

client.setFingerprint(echo_org_ssl_fingerprint);

or you could use the setKnownKey() method to specify the public key of a certificate in order to validate the server you are connecting to.

PublicKey *publicKey = new PublicKey(public_key);
client.setKnownKey(publicKey);

or you can specify the Certificate Authority (CA) using setTrustAnchors method, as follows:

X509List *serverTrustedCA = new X509List(ca_cert);
client.setTrustAnchors(serverTrustedCA);

For client-side certificate validation, you can use RSA or EC certificates, using the method setClientRSACert or setClientECCert .

ESP32

With the ESP32 you could either provide the full certificate, or provide no certificate. An example for setting CA Certificate:

// KH, This certificate was updated 15.04.2021, 
// Issued on Mar 15th 2021, expired on June 13th 2021
const char echo_org_ssl_ca_cert[] PROGMEM = \

client.setCACert(echo_org_ssl_ca_cert);

From v1.2.4, you can use InSecured mode which does not validate the certificate chain. This can be set explicitly using:

client.setInsecure();

Debug

Debug is enabled by default on Serial. Debug Level from 0 to 4. To disable, change the _WEBSOCKETS_LOGLEVEL_ to 0

// Use this to output debug msgs to Serial
#define DEBUG_WEBSOCKETS_PORT     Serial
// Use this to disable all output debug msgs
//#define DEBUG_WEBSOCKETS_PORT
// Debug Level from 0 to 4
#define _WEBSOCKETS_LOGLEVEL_     3

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, applying Libraries' Patches, Packages' Patches or this library latest version.

Contributions and Thanks

  1. Based on and modified from Gil Maimon's ArduinoWebsockets

  2. Thanks to good work of Miguel Alexandre Wisintainer for initiating, inspriring, working with, developing, debugging and testing. Without that, support to nRF52, especially NINA_B302_ublox running as nRF52840 and NINA_B112_ublox running as nRF52832, has never been started and finished. See u-blox nina b

  3. Thanks to bug report and persistence of Jake to help identify and add non-blocking WebSockets Server feature to v1.0.6 to enable WS Server and WebServer running concurrently. See Support as Http server and the Websockets server on Arduino DUE and Running Http and Websocket Servers concurrently.

  4. Thanks to arnoson code posted in ArduinoWebsockets release 0.5.0 to provide support to Teensy 4.1 using NativeEthernet.

  5. Thanks Lionel REICHERT for PR Add setInsecure for esp32 #18 leading to v1.2.4.

  6. Thanks to Jose A.Molina for the enhancement request MKR1000 and WIFI problem and another problem #20, and help testing, leading to new version v1.3.0 to support WiFi101 and MKD1000 / MKR1010WiFi boards.

websockets2_generic's Issues

Compiler warnings

Hello, I get many compiler warnings using Teensy 4.1 and native ethernet. Even if everything works perfectly, it pollutes the compiler output and it is not really helpfull. Anything to do about it?

VSCode + PIO for Teensy4.1 compilation error. Complaining stm32_eth.h missing!

Setup and Target information:

  • Visual Studio Code
  • PlatformIO Core, version 5.0.4
  • Teensy4.1 (so STM32) with built in ethernet ()
  • Operating system macOS 10.14.6

Note: The library was installed using platformio's library manager

Simplest platformio.ini file content:

[env:teensy41]
platform = teensy
board = teensy41
framework = arduino
lib_deps = khoih-prog/WebSockets2_Generic@^1.8.1

Simplest main.cpp content:

#include <Arduino.h>

void setup()
{
  // put your setup code here, to run once:
}

void loop()
{
  // put your main code here, to run repeatedly:
}

The problem:

Screenshot 2021-10-15 at 4 13 26 PM

While trying to compile against Teensy4.1 with built in Ethernet, it not compiling but throwing errors complaining that:

  1. In <proj_dir>/.pi/libdeps/teensy41/STM32Ethernet/src/utility/stm32_eth.h, the reference stm32_def.h can not be located. Screenshot 2021-10-15 at 4 32 59 PM

  2. And that in <proj_dir>/.pio/build/teensy41/lib24a/STM32Ethernet/utility/, the stm32_eth.cpp is also missing.

Don't know what's happening 😶
I guessing no need to use any patch files like in case of Arduino IDE installation, mentioned in the README?
(That's one reason for me to choose PIO in VS code over Arduino IDE)

Any pointers?

Error 1006

I'm Using ESP8266-Client.ino Example and connected to this site : https://socketsbay.com/test-websockets
i change
in defines.h
const char* websockets_server_host = "socketsbay.com"; //Enter server address
#define WEBSOCKETS_PORT 443 //8080

and in io file
bool connected = client.connectSecure(websockets_server_host, websockets_server_port, "/wss/v2/2/demo/");

it's work fine
but after 50 second the connection is close with code 1006

can you test and check why the connection close with code 1006

Thank you

Missing stm32_def.h for Teensy 4.1

PlatformIO Core, version 5.1.0
Windows 10 Enterprise
Board: Teensy 4.1
Framework: Arduino

Hi, I am trying to build a project in PlatfromIO for the Teensy 4.1 with this library added to platform.ini. It does not compile successfully. I get the following error 8 times before the compilation is terminated:

".pio\libdeps\teensy41\STM32Ethernet\src\utility\stm32_eth.h:42:23: fatal error: stm32_def.h: No such file or directory"

Why would there be STM32 files under the teensy41 core?

My platform.ini file looks as follows:

[env:teensy41]
platform = teensy
board = teensy41
framework = arduino
lib_deps = 
    https://github.com/vjmuzik/FNET.git
    https://github.com/vjmuzik/NativeEthernet.git
    https://github.com/sstaub/TeensyID.git
    https://github.com/khoih-prog/WebSockets2_Generic.git

Steps to reproduce:

  1. Open PIO project for Teensy 4.1 board
  2. Add Github link for FNET to platformo.ini file: https://github.com/vjmuzik/FNET.git
  3. Add Github link for NativeEthernet to platformio.ini file: https://github.com/vjmuzik/NativeEthernet.git
  4. Add Github link for TeensyID to platformio.ini file: https://github.com/sstaub/TeensyID.git
  5. Add Github link for WebSockets2_Generic to platformio.ini file: https://github.com/khoih-prog/WebSockets2_Generic.git
  6. Build project

ESP32-Server Not Working Properly

i have uploaded esp32 server code from examples.

        2. Starts a websocket server on port 8080
        3. Waits for connections
        4. Once a client connects, it wait for a message from the client
        5. Sends an "echo" message to the client
        6. closes the connection and goes back to step 3

Examples Generic WiFiNINA RP2040 ServerAllFunctionsDemo does not work

Describe the bug

This sample is non functional: https://github.com/khoih-prog/WebSockets2_Generic/tree/master/examples/Generic/WiFiNINA/RP2040/RP2040_ServerAllFunctionsDemo

Steps to Reproduce

Using an Arudino Nano RP2040 Connect, upload the noted example.

Expected behavior

The RGB sliders would actually work, changing the onboard LED colors.
Sending data to the hosted socket would also display the data received.

Actual behavior

The RGB sliders do not do anything. The onboard LED remains off.
When sending data to the hosted socket, the board acknowledges that a message has been received, however zero data is displayed, even when sending data to it.

Information

Arduino IDE version: 2.0.3
Arduino Mbed OS RP2040 3.5.1
NANO RP2040 CONNECT

MKR1000 and socket.io

Hello,

Can your library be used to communicate with a websocket server created with nodejs + express + socket.io?
Can it simultaneously be used to call a rest api made with nodejs + express?
Do you have examples using rest api?
Can it be used with a MKR1000 and Wifi101?
Do you have examples using Wifi101?

Thank you very much for all your information.

Compile for Arduino Leonardo fails for missing STL

Hi

At first I would to say I'm new to Arduino world, that excuse me in advance if I made a mistake somewhere. Basically I have the Arduino Leonardo board with an ethernet shield with W5500 chip. I would to use your library to exchange data through WebSocket library but, using Visual Studio Code with platformio, I can't compile. The error refer to the include file not found. Googling around I discovered that AVR compiler miss the STL support but after tried to add some alternative package for import STL I still receive errors because you code makes heavy use of the STL library. I tried to read all the tutorial here but I don't understand yet if I miss some steps or is not possible to use the library with Leonardo board.

Can you help me?

Thank you

MKR1000 and WIFI problem and another problem

Describe the bug

I am running the sample program "SAMD-Minimal-Client", but it has a problem when it reaches any WIFI line.

Arduino IDE 1.8.15
Arduino MKR 1000
Installed libraries:
WiFiNINA_Generic v1.2.4
WebSockets2_Generic v1.8.5

sc10

Steps to Reproduce

When I compile the sample program I get some strange lines before finishing compilation (ScreenShot sc05.jpg).
I have added some lines to the code Serial.prinln ("1") ... (ScreenShot sc06.jpg) to see where the execution of the program goes.
As you will see in the screenshot, on the serial monitor, the program correctly detects my MKR1000, but it does not pass the Serial.print (1) line, that is, it remains blocked in WiFi.status () (ScreenShot sc07.jpg)
Even if you disable several lines in the program prior to the WiFi connection (ScreenShot sc08.jpg), it always stays blocked, even on the WiFi.begin line (ScreenShot sc09.jpg).
You can also see in the screenshots that I have used the firmware check programs and another example program from the Wifi101 library to check the WiFi connection and everything works perfectly (ScreenShots sc01, sc02, sc03, sc04). That is, the problem is when using your library.
Am I doing something wrong or is it a bug in your library?
Look at all the screenshots.

Multiple Clients Teensy41 server example QNEthernet

HI,
When trying to run the following example, my teensy seems to get stuck in a loop of accepting new websocket client connections. I don't quite understand what is happening. I'm using the latest build of QNEthernet. Doesn't seem to happen with Native Ethernet.
Possibly didn't happen on versions prior to latest release?

https://github.com/khoih-prog/WebSockets2_Generic/blob/master/examples/Generic/Teensy41_QNEthernet/MultipleClients_Teensy41_Server/MultipleClients_Teensy41_Server.ino

Terminal output is

Accepted new websockets client at index 0
Accepted new websockets client at index 0
Accepted new websockets client at index 0

I'm a bit of an Arduino noob so I'm not exactly sure how to fix this (yes my project is a bit ambitious, but I can pull it off).

Here's my project's code repository: https://github.com/jackmerrill/FriendshipLamp

I copied some code from the Generic WifiNINA SAMD project, https://github.com/khoih-prog/WebSockets2_Generic/tree/master/examples/Generic/WiFiNINA/SAMD/SAMD-Client

the EasyWifi is another repository that I slightly modified in an attempt to get it working with WiFiNINA_Generic.

Any and all help is appreciated, thank you!

multiple definition of `websockets2_generic::WebsocketsServer::....'

Hello,

Firstly thanks for the work you've put into the library.

I'm using ver 1.1 of your library in conjunction with Sloeber on Eclipse on a 8266.

I have an issue which seems related to a closed bug report (#3) but I haven't been able to solve it with your proposed solution.

I have the following setup:

sensor.ino


#include "LwDevice.h"
#include <Arduino.h>

lwDevice lwNode;

setup()

loop()

lwDevice.cpp


#include "LwDevice.h"
#include <Arduino.h>

using namespace std;

namespace lw {

int LwDevice::sendSocketJSON(){

//websockets2_generic::WebsocketsClient socket; Compiles ok if initialised here
do socket stuff...

}
}

lwDevice.h

#include <WebSockets2_Generic.h>

namespace lw {

class LwDevice {
private:
websockets2_generic::WebsocketsClient socket; // lots of multiple def errors when init here

}
}

So when creating the object inside the sendSocketJSON() it compiles correctly, moving it to the class causes multiple definition errors.
E.g:
/opt/eclipse/arduinoPlugin/packages/esp8266/hardware/esp8266/2.7.0/libraries/EEPROM/EEPROM.cpp:108: multiple definition of EEPROMClass::write(int, unsigned char)'; ./libraries/ESP_EEPROM/src/ESP_EEPROM.cpp.o:/opt/eclipse/arduinoPlugin/libraries/ESP_EEPROM/2.1.1/src/ESP_EEPROM.cpp:296: first defined here /opt/eclipse/arduinoPlugin/packages/esp8266/tools/xtensa-lx106-elf-gcc/2.5.0-4-b40a506/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: ./libraries/EEPROM/EEPROM.cpp.o: in function EEPROMClass::commit()':

Any pointers would be gratefully appreciated,

Endless loop reading line from client

Teensy41_NativeEthernet_tcp.hpp, line 103:

WSString readLine() override
{
  WSString line = "";

  int ch = -1;

  while ( ch != '\n' && available())
  {
    // It is important to call `client.available()`. Otherwise no data can be read.
    if (client.available())
    {
      ch = client.read();

      if (ch >= 0)
      {

    }
  }

  return line;

sometimes client.available() return false, but available() still true then the loop is endless

WebSockets2_generic library and MKR1000 + Ethernet Shield

Hi Khoih,

I'm trying to use the WebSockets2_generic library with the Arduino MKR1000 + Ethernet Shield, but it can't even connect to the server.
I am using your example (SAMD-Ethernet-Client) which is prepared for the MKR1000.
I have installed the patches from the Ethernet library and the EthernetLarge library, but with neither of the 2 it manages to connect to the nodejs server.
Produces the following output:

12:18:04.435 -> 
12:18:04.435 -> Starting SAMD-Ethernet-Client on SAMD MKR1000
12:18:04.435 -> Ethernet using W5x00 and Ethernet Library
12:18:04.435 -> WebSockets2_Generic v1.8.1
12:18:04.982 -> 
12:18:04.982 -> W5100 init, using SS_PIN_DEFAULT = 5, new ss_pin = 10, W5100Class::ss_pin = 10
12:18:04.982 -> no chip :-(
12:18:04.982 -> WebSockets Client IP address: 0.0.0.0
12:18:04.982 -> Connecting to WebSockets Server @192.168.20.100
12:18:04.982 -> [WS] WebsocketsClient::connect: step 1
12:18:04.982 -> [WS] WebsocketsClient::connect: not _connectionOpen, host = 192.168.20.100 , port = 8080
12:18:04.982 -> Not Connected!

Your WebSockets_generic library manages to connect with socket.io, but your WebSockets2_generic library doesn't even connect.
According to your documentation the WebSockets2_generic library should work without problems with the MKR1000 + Ethernet Shield just like your WebSockets_generic library.

What could be happening?
I am doing something wrong?

Thanks for your help.
Regards,
Jose

Portenta WiFi Websockets tested lately?

Hi @khoih-prog any idea if anyone has lately tested the PortentaH7 with this library. I can't seem to get websocket type chat working.

I do use a web based websocket server, but that shouldn't be the issue. If I use 2 Portenta's is there an easily way to test if they are working?

I am using this example folder

https://github.com/khoih-prog/WebSockets2_Generic/tree/master/examples/Generic/Portenta_H7/WiFi

I really just want an SSL websocket client, but should I just be able to test one Portenta as a client and one as the server?

Actually that seems fairly simple. I will test that out.

......

Ok I tested the Portenta server and client. Looked fairly easy to understand. But no connection


Connected to Wifi, IP address: 192.168.137.36
Connecting to WebSockets Server @192.168.137.128
[WS] WebsocketsClient::connect: not _connectionOpen, host = 192.168.137.128 , port = 8080

Any idea why?

Multiple definition errors due to non-standard naming convention

Hello,
First of all, thank you for your work on this very useful library.
As several people have already pointed out in #3 and #15, using WebSockets2_Generic in a project that consists of multiple source files can lead to "multiple definition" errors while linking. The reason for this is that most of the code in this library is inside .hpp files which are #include-ed. This is not standard practice - in C++ source code should be in .cpp files which do not get #include-ed but instead are linked together after compilation by the linker.
Do you have a good reason to break such a fundamental C++ convention? If not, can you please rename your source files to *.cpp to prevent linking errors? This is the only issue that stops me from recommending this library as the best websocket library for embedded projects.

WebSocket doesn't connect without a CA certificate.

I am using NodeMcu 32s with WebSockets2_Generic v1.1.0
As per the documentation CA cert is not necessary.
3
But I can't find a way to connect without a CA cert.
In my previous library for Esp 8266 it works without a CA cert.
but it not provide this feature for Esp32.

I need a persistent connection without worry about CA cert validity.

Ethernet and wifi in the same board

Hi

I'm using the arduino mkr wifi 1010 with the ethernet shield (W5500) because, in case of no wifi available, ethernet must be the alternative for connect to the server. I wanted to use your library for communicate using both solutions but it seem is not possible. To be more precise the problem is all the library code is all inside the .hpp header (why?) and is not possible to include the same header in two different .cpp (one configured for wifi and other for ethernet). Including in both source files generate a linker error caused by the conflict of the double function body compiled in the same project. Do you know if exist a workaround for have both devices wifi and ethernet working in the same firmware?
Thank you

what is websocketclient if no incoming request?

after

client = SocketsServer.accept();

after no incoming client connection request,

is it a single client object? only one client allowed at a time?

how can I push messages to the client asynchronously?

I would build an array of clients from accept
and loop thru each for incoming messages,
but send based on other events, data status change, elasped time....

Is it compatible with MRK GSM 1400?

Arduino MKR GSM 1400
SAMD core version 1.8.9
Arduino IDE 1.8.13
MacOS 10.13.6

I was wondering whether I could connect through WebSocket with this library and the MRK GSM 1400 board?

I built the project and ran it with a dummy configuration but I couldn't pass step 1 when it tries to connect.

Output:
01:40:17.153 -> Starting SAMD-Ethernet-Minimal-Client on SAMD MKRGSM1400
01:40:17.153 -> Ethernet using W5x00 and Ethernet Library
01:40:17.153 -> WebSockets2_Generic v1.1.0
01:40:17.153 -> [WS] WebsocketsClient::connect: step 1

Thanks!

RP2040 WebSocket immediate disconnection

Bug

Starting from "RP2040_ServerAllFunctionsDemo.ino" from File > Examples > WebSockets2_Generic > Generic > WiFiNINA > RP2040 .
After some fixes (explained below) I can connect but I cannot maintain the communication open.

Steps to Reproduce

  • Used generic RP2040_ServerAllFunctionsDemo.ino from File > Examples > WebSockets2_Generic > Generic > WiFiNINA > RP2040 .
  • Set correct ssid and password in defines.h
  • Set the correct wsServer url in line 100
  • Went to the ip address:80 and saw the RGB sliders

Expected behavior

Socket connection opened and communication happening (not interested in RGB to really work but the communication to being established).

Actual behavior


PROBLEM: Javascript error: "Uncaught ReferenceError: wsServer is not defined" .

SOLUTION: Solved by replacing in line 106 this:
var connection = new WebSocket(wsServer, ['arduino']);
with:
var connection = new WebSocket('ws://'+window.location.hostname+':8080/', ['arduino']);
Compiled and uploaded new code.

RESULT: problem 1 solved, but I receive "WebSocket Error"


PROBLEM: WebSocket Error

SOLUTION: Solved by developing my own script available below:

    var wsClientOutput;

    function init() {
        testWebSocket();
    }

    function testWebSocket() {
        websocket = new WebSocket("ws://192.168.2.123:8080/"); //change with yours
        websocket.onopen = function (evt) {
            onOpen(evt)
        };
        websocket.onclose = function (evt) {
            onClose(evt)
        };
        websocket.onmessage = function (evt) {
            onMessage(evt)
        };
        websocket.onerror = function (evt) {
            onError(evt)
        };
    }

    function onOpen(evt) {
       console.log("OPEN")
    }

    function onClose(evt) {
        console.log("DISCONNECTED");
    }

    function onMessage(evt) {
        console.log('RESPONSE: ' + evt.data);
    }

    function onError(evt) {
        console.log('ERROR:' + evt.data);
    }

    function doSend(message) {
        console.log("SENT: " + message);
        websocket.send(message);
    }

   
    window.addEventListener("load", init, false);

RESULT: I can connect but I quickly disconnect.


PROBLEM: Immediate disconnection after connection

SOLUTION: I removed line 140 and line 143 from "RP2040_ServerAllFunctionsDemo.ino "
Compiled and uploaded new code.

RESULT: same error. Immediate disconnection after connection.

WebSockets2_Generic on Mega2560 with w5100 ethernet shield

Hello!
Is it possible to run this library on a Mega2560 with w5100 ethernet shield?
I want to set up my Alexa Gateway with Sinric over Lan.

I cannot find a working example for my setup and always get a compatibility error ("This code is intended to run on...").

Thanks in Advance!

CA Certificate not getting verified ?

Describe the bug

The WebSocket Client doesn't seem to verify the CA Certificate even when one is provided through "client.setCACert(ssl_ca_cert)" method.

Steps to Reproduce

  1. Enter Correct Certificate to the Sketch (Or just use the git provided example).
  2. Change a few letters of the certificate.
  3. Try to connect, and the client will connect to the server.

PS: client.setInsecure() method had NOT been used;

Expected behavior

Client should not connect to the Server.

Actual behavior

Client connects to the Server.

Connect() is blocking?

Looking at the example code: bool connected = client.connect(websockets_connection_string); it seems to me that connect() will block until the connection is made or fails. Is that correct? Is there any way to perform the connection in the background and use the event callback to detect connection?

RobotDyn SamD21 M0 Zero compatible board

I was testing the example in https://github.com/khoih-prog/WebSockets2_Generic/tree/master/examples/Generic/Ethernet/SAMD/SAMD-Ethernet_AdvancedWebServer
but got nothing in the serial output.

These clone boards (https://www.aliexpress.com/item/32780674095.html?spm=a2g0s.9042311.0.0.27424c4dcsNo3b) are called Zero compatible, but don't have 2 USB ports like a real Zero (serial programming and serial USB).
The only port they have is the serial USB

So I had to add following code in the sketch example:

#if PLATFORM_ARCH == PLATFORM_ARCHITECTURE_SAMD21
#  define _SERIAL SerialUSB
#else
#  define _SERIAL Serial
#endif

and to use everywhere
_SERIAL.println

Loop function hangs even without the poll function

Hi it's me again haha. When I run my code on the board, it only seems to run the loop function once, but if I remove / comment out any of the Websocket code, it works completely fine (lines 162 and 194).

Code: https://github.com/jackmerrill/FriendshipLamp/blob/main/Friendship_Lamp.ino

Here's how I know it doesn't loop:

23:11:39.759 -> Connnection Opened
23:11:39.759 -> Connected!
23:11:39.759 -> available
23:11:39.759 -> on
23:11:39.759 -> number of button pushes: 1
23:11:39.759 -> color

available and beyond should be printing more than just once.

Any and all help is appreciated, thanks!

Enhancement:

Hello,

Unfortunately I can contribute less code than I would like to, but thanks again for the great work.

The new unblocking function was successfully tested, thanks!
But unfortunately it reads the websocket connection immediately after sending the echo.
This is unfortunately exactly the problem.
Actually, it's just the server that outputs the data until the web socket is closed by the client.

What would I like to achieve.

  1. the client connects to the webserver and presses a html butt, we say "Enable Logging".
  2. a new page is called and from the webserver and in it is a javascript that opens the websocket to the server.
  3. the browser now sends its request to the server via the websocket... which in turn replies with a string example current time
    (actually I want to display the debug output of a traffic " DCC ". )
  4. from now on the browser (javascript) waits for data from the server to output it as http.
  5. the server outputs the current time/DCC data via the socket
  6. enough of the output is after 5 min or on e.g. an "exit" butten the Websock bzzw the logging is terminated.

As I understood it should work like this, but step 3 closes the websock at the end of the logging process. For it to work the Javascript would have to rebuild the websock again and again. That would be the same with Ajax and because Ajax asks for time you want a websocket that can send / receive data bidirectional and reduce the html overhead.

Is it possible to implement this?
I try to give you the full understand what I need, if not please ask.
Or is that possible and I have overlooked how !

greeting
Jake

Uploading and running example of ESP "Minimal-Esp32-Client" error [ 4159][E][WiFiClient.cpp:313] setSocketOption(): fail on -1, errno: 9, "Bad file number"

Describe the bug

I tried to run the example of ESP32 called "Minimal-Esp32-Client" (and other examples, but this one is the easiest to reproduce), then the monitor printed

[ 4159][E][WiFiClient.cpp:313] setSocketOption(): fail on -1, errno: 9, "Bad file number"

and then
Not Connected!

Steps to Reproduce

I am using visual studio code with PlatformIO and created a new project of ESP32 on Arduino framework.
Just put the example code "Minimal-Esp32-Client" with your wifi ssid and password and the websocket server to connect to and it will do it

PlatformIO version: Core 6.1.4 - Home 3.4.3
Core Version: I am not sure, i think Arduino-mbed
Board type: ESP32
Contextual information: I tried to run the example code
Using Windows 10

multiple definition of `websockets2_generic::WebsocketsServer::~WebsocketsServer()' in websocket2_generic library

HI.

I’m using ‘adafruit feather m0’ board with w5500 and I succeed to run example code “SAMD-Ethernet-Client”. Also, I communicate server using websocket2_generic library. Then I want to separate code into two files.

While I was trying to make separate WebSocket header file using websockets2_generic library, I face weird error. I try to figure out it, but It was very complicated with my codes. Thus, I remove all of my code except necessary things such as “#define” and “#include”.

I have four files which is

SAMD-Ethernet-Client.ino
EthernetWebSocketsClient.h
EthernetWebSocketsClient.cpp
defines.h

As the file name, I use the example code. defines.h is almost same with example code. I just remove unnecessary global values.
Other files are same below.

SAMD-Ethernet-Client.ino

#include "EthernetWebSocketsClient.h"
    
void setup()
{}
    
void loop()
{}

EthernetWebSocketsClient.h

#ifndef EWC_H
#define EWC_H
    
#include "defines.h"
#include <WebSockets2_Generic.h>
     
#endif

EthernetWebSocketsClient.cpp

#include "EthernetWebSocketsClient.h"

As I mentioned before, I remove all the code. Those are the full code. When compiling, it shows error like below

c:/users/chanyoung/appdata/local/arduino15/packages/adafruit/tools/arm-none-eabi-gcc/9-2019q4/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: C:\Users\CHANYO1\AppData\Local\Temp\arduino_build_4918\sketch\SAMD-Ethernet-Client.ino.cpp.o: in function std::function<void (websockets2_generic::WebsocketsClient&, websockets2_generic::WebsocketsMessage)>::operator bool() const': C:\Arduino\libraries\WebSockets2_Generic-master\src/Tiny_Websockets_Generic/internals/wscrypto/sha1.hpp:73: multiple definition of websockets2_generic::WebsocketsServer::WebsocketsServer()'; C:\Users\CHANYO1\AppData\Local\Temp\arduino_build_4918\sketch\EthernetWebSocketsClient.cpp.o:C:\Arduino\libraries\WebSockets2_Generic-master\src/WebSockets2_Generic_Server.hpp:182: first defined here

It shows multiple definition.

I change codes in EthernetWebSocketsClient.h, SAMD-Ethernet-Client.ino.

SAMD-Ethernet-Client.ino

#ifndef EWC_H
#define EWC_H
    
#endif

SAMD-Ethernet-Client.ino

#include "defines.h"
#include <WebSockets2_Generic.h>
    
#include "EthernetWebSocketsClient.h"

void setup()
{}
    
void loop()
{}

I just change the location of

#include "defines.h"
#include <WebSockets2_Generic.h>

Then, I succeed to compile and linking.

I want to implement websocket functions in EthernetWebSocketsClient.cpp file. Thus, EthernetWebSocketsClient.h include websocket2_generic library.

How can I include websocket2_generic library in EthernetWebSocketsClient.h file.

Serious problem with timeout when sending packages

Hi,

We've developed a solution using the Pico 2040W that gets data from an Acconner radar chip (core 1) and saves this into a circular buffer that is then read and uploaded (core 0) using this library. We're using the WifiMulti library to connect and manage our wireless network connection, and I've done extensive testing to make sure that library functions as intended – it does.

Our main concern is that the thread (core 0) responsible for offloading the radar frames, sent as binary data, randomly freezes when the connection is bad or when the connection to the websocket is lost. Sometimes this seems to happen without an actual closed event being fired, and the available() method also returns a status indicating that the connection is alive and well, despite the connection obviously not working.

Since our application is led to believe that the connection is still working, we proceed with trying to send data – and this process seems to have a very long timeout, hanging our core on each and every send for approximately 5 seconds, before returning true, indicating that a send was indeed successful, despite that not being the case.

So there seems to be multiple problems:

  1. The first one being that the library doesn't detect if the connection actually drops and available() keeps saying that the connection is fine.
  2. The send method found here is still called, despite the connecting not being available, and the _client send method seems to have a timeout of about 5000 ms.
  3. The third and final issue also has to do with line linked above. That the send method assumes that the transfer went through, which is just not a good idea for a TCP transfer, and means that our application is fooled yet again.

Are there any prospects for solutions on these issues? If not I think that we'll unfortunately have to move to a plain TCP socket based solution as the embedded code is dependent on issues like this not happening.

Thank you! :)

Running Http and Websocket Servers concurrently

@jakespeed1311

This is an issue from WebSockets_Generic Library relating to this WebSockets2_Generic Library

Support as Http server and the webscok server on Arduino DUE

Moving it now to the correct place

Probably it works because your clients are constantly querying the websocket and can do that ?

If you specify your problem early, it'll be helpful and save time

OK, if I understand correctly now, your problem is that

  1. the WebSocketServer is in blocking mode
  2. you don't have any WebSockets Client
  3. WS Server is blocked, waiting for Client before moving forward
  4. The HTTP WebServer can't continue.

If so, I think I can fix the problem by modifying the WebSockets2_Generic Library.

Please wait until I find out the fix and post the new release.

I'm moving the issue to the correct place of WebSockets2_Generic Library.

QNEthernet higher latency

First, many thanks for an awesome library!

I would like to report a bug and a possible solution but not sure if this introduces any other issues but this seems to have improved the problem for me..

Describe the bug

When using QNEthernet on a teensy 4.1 websocket server, there seems to be 5-6x latency compared to Native ethernet when sending data
using client.send

Reading https://github.com/ssilverman/QNEthernet#write-immediacy

It seems that the client.write waits for a timeout or enough data to send that adds about 150ms delay for each call

This change in Teensy41_QNEthernet_tcp.hpp seems to correct the problem

void send(const WSString& data) override
{
 client.write(reinterpret_cast<uint8_t*>(const_cast<char*>(data.c_str())), data.size());
 **client.flush();** 
}

void send(const WSString&& data) override
{
 client.write(reinterpret_cast<uint8_t*>(const_cast<char*>(data.c_str())), data.size());
 **client.flush();**
}

void send(const uint8_t* data, const uint32_t len) override
{
 client.write(data, len);
 **client.flush();**
}

[Questions] How to receive binary data?

Questions 1
Example is ESP32_WebSocketClient.ino
How to receive binary data?

Questions 2
Sometimes the connection with the server is lost.
When the connection to the server is lost

client.connect(websockets server_host, websockets server_port, "/");

doesn't connect, is there any other way?

thank you

Docs?

Are there any docs? API? The examples are helpful, but for instance, I'm not sure what exactly client.available() does, nor e.g. how many different callbacks are available. (Also, it looks like onEventsCallback in the README is never used?) The many-targeted nature of the code makes it hard to search the code for a definitive answer. It sounds like this project is based on another - is there other documentation elsewhere that is considered canon for this library, too?

Client IP address availability?

Thanks for a great library

I cant seem to find the following anywhere.

I am using the Teensy41_Server.ino websocket server is it possible to have a method to get the websocket client's IP address please? Or is there any other way to do so?

Eg client.remoteIP() ?

This is useful for IP filtering etc.

Many thanks
Marios

Fast Websocket sending causes stuttering?

I'm using an Arduino Nano 33 iot with the WifiNina client example. I'm sending over data every 16ms and the data all gets to where it needs to go although it stutters. It's as if I'm receiving the data in chunks rather than quickly every 16ms. Do you guys know of some reason this might occur? I'm trying to send string data which looks like "123,145,156,674" per message.

Error Compiling for board MKR WiFi 1010

Describe the bug

I am currently trying with this library and other dependent libraries which have been installed as well. The first 2 errors are the following. I really don't know how to fix this...
I didn't define the define.h as you did in the example. Is that very necessary to do this?

Actual behavior

But something wrong happened and I don't know why...

Information

Please ensure to specify the following:

  • Arduino IDE version 1.8.19
  • STM32
  • We just wanna open a websocket port using "client" so that the msg sent from server could be obtained.
