Why do we need this AsyncHTTPRequest_ESP32_Ethernet library

Features

  1. Asynchronous HTTP Request library for ESP32/S2/S3/C3, WT32_ETH01 (ESP32 + LAN8720), ESP32 using LwIP ENC28J60, W5500, W6100 or LAN8720.
  2. Providing a subset of HTTP.
  3. Relying on AsyncTCP
  4. Methods similar in format and usage to XmlHTTPrequest in Javascript.

Supports

  1. GET, POST, PUT, PATCH, DELETE and HEAD
  2. Request and response headers
  3. Chunked response
  4. Single String response for short (<~5K) responses (heap permitting).
  5. Optional onData callback.
  6. Optional onReadyStatechange callback.

Principles of operation

This library adds a simple HTTP layer on top of the AsyncTCP library to facilitate REST communication from a Client to a Server. The paradigm is similar to the XMLHttpRequest in Javascript, employing the notion of a ready-state progression through the transaction request.

Synchronization can be accomplished using callbacks on ready-state change, a callback on data receipt, or simply polling for ready-state change. Data retrieval can be incremental as received, or bulk retrieved when the transaction completes provided there is enough heap to buffer the entire response.

The underlying buffering uses a new xbuf class. It handles both character and binary data. Class xbuf uses a chain of small (64 byte) segments that are allocated and added to the tail as data is added and deallocated from the head as data is read, achieving the same result as a dynamic circular buffer limited only by the size of heap. The xbuf implements indexOf and readUntil functions.

For short transactions, buffer space should not be an issue. In fact, it can be more economical than other methods that use larger fixed length buffers. Data is acked when retrieved by the caller, so there is some limited flow control to limit heap usage for larger transfers.

Request and response headers are handled in the typical fashion.

Chunked responses are recognized and handled transparently.

This library is based on, modified from:

  1. Bob Lemaire's asyncHTTPrequest Library

Installation

Use Arduino Library Manager

The best and easiest way is to use Arduino Library Manager. Search for AsyncHTTPRequest_ESP32_Ethernet, then select / install the latest version. You can also use this link arduino-library-badge for more detailed instructions.

Manual Install

  1. Navigate to AsyncHTTPRequest_ESP32_Ethernet page.
  2. Download the latest release AsyncHTTPRequest_ESP32_Ethernet-main.zip.
  3. Extract the zip file to AsyncHTTPRequest_ESP32_Ethernet-main directory
  4. Copy the whole AsyncHTTPRequest_ESP32_Ethernet-main folder to Arduino libraries' directory such as ~/Arduino/libraries/.

VS Code & PlatformIO

  1. Install VS Code
  2. Install PlatformIO
  3. Install AsyncHTTPRequest_ESP32_Ethernet library by using Library Manager. Search for AsyncHTTPRequest_ESP32_Ethernet in Platform.io Author's Libraries
  4. Use included platformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at Project Configuration File

Note for Platform IO using ESP32 LittleFS

In Platform IO, to fix the error when using LittleFS_esp32 v1.0.6 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 Fix Multiple Definitions Linker Error

The current library implementation, using xyz-Impl.h instead of standard xyz.cpp, possibly creates certain Multiple Definitions Linker error in certain use cases.

You can include this .hpp file

// Can be included as many times as necessary, without `Multiple Definitions` Linker Error
#include "AsyncHTTPRequest_ESP32_Ethernet.hpp"     //https://github.com/khoih-prog/AsyncHTTPRequest_ESP32_Ethernet

in many files. But be sure to use the following .h file in just 1 .h, .cpp or .ino file, which must not be included in any other file, to avoid Multiple Definitions Linker Error

// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error
#include "AsyncHTTPRequest_ESP32_Ethernet.h"           //https://github.com/khoih-prog/AsyncHTTPRequest_ESP32_Ethernet

Check the new multiFileProject example for a HOWTO demo.

Have a look at the discussion in Different behaviour using the src_cpp or src_h lib #80

Note for Platform IO using ESP32 LittleFS

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.

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).

Debug

Debug is enabled by default on Serial.

You can also change the debugging level from 0 to 4

#define ASYNC_HTTP_DEBUG_PORT           Serial

// Use from 0 to 4. Higher number, more debugging messages and memory usage.
#define _ASYNC_HTTP_LOGLEVEL_           1

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the ESP32 core for Arduino.

Sometimes, the library will only work if you update the ESP32 core to the latest version because I am using newly added functions.

Issues

Submit issues to: AsyncHTTPRequest_ESP32_Ethernet issues

TO DO

  1. Fix bug. Add enhancement
  2. Add support to more LwIP Ethernet shields

DONE

  1. Initially add support to ESP32/S2/S3/C3 boards using LwIP W5500 / ENC28J60 / LAN8720 Ethernet
  2. Sync with AsyncHTTPRequest_Generic v1.12.0
  3. Use allman astyle and add utils. Restyle the library
  4. Add support to ESP32S2/C3 boards using LwIP W5500 or ENC28J60 Ethernet
  5. Add support to ESP32 and ESP32S2/S3/C3 boards using LwIP W6100 Ethernet
  6. Fix _parseURL() bug. Check Bug with _parseURL() #21
  7. Improve README.md so that links can be used in other sites, such as PIO

Contributions and Thanks

This library is based on, modified, bug-fixed and improved from:

  1. Bob Lemaire's asyncHTTPrequest Library to use the better asynchronous features of these following Async TCP Libraries : ( ESPAsyncTCP, AsyncTCP, and STM32AsyncTCP ).
