mbed-ble-hid's Issues

Issue with W7 and CRS Harmony BT adapter.

Hi ,
this code works perfrectly with Android device and W10 PC with native BT adaperr. On my desktop with W7 and a CRS Harmony BT usb adaper it doesn't ,because return the message "wrong code entered" , like if he try to do a pairing with pin code , while on Android and other PC isn't required the pairing with pin code. Is there any way to solve this issue ? Tks. Roberto

Not able to send LEFT_ARROW or any FunctionKeyChar_t

I am not able to send function keys using this library. Is there a problem with me (I assume) or with the library? I have used the Arduino forum with no luck. I am using the ble_shining_kb example with a Nano 33 BLE and I can send text but just cannot send a control character from the HIDKeyboardService.h ...

sendCharacter(LEFT_ARROW);
or

KeySym_t testSym_t = KeySym_t(LEFT_ARROW,0); kb->keydown(testSym_t); kb->keyup();

call of overloaded 'millis()' is ambiguous

I have a simple platformio project.
Compiling gives the following error:

.pio\libdeps\nano33ble\Mbed BLE HID\src\Mbed_BLE_HID.cpp:151:30: error: call of overloaded 'millis()' is ambiguous

I have also tried version 1.3.0 with same outcome.
Older than 1.2.0 give other errors.
What could be the problem?

platformio.ini

[env:nano33ble]
platform = nordicnrf52
board = nano33ble
framework = arduino

lib_deps = 
    tcoppex/Mbed BLE [email protected]

main.cpp

#include <Arduino.h>
#include <USBKeyboard.h>

static USBKeyboard Keyboard;

void setup(){

}

void loop(){
  delay(1000);
  Keyboard.printf("Hello world\n\r");
}

Output Report Support

Looking within the HIDService.h, I can see that output reports are only partially supported, with the BLE characteristic defined and enum values. However there is no method of receiving the report. I've tried to expand upon this with the following function, however it doesn't seem to work. Did you have any implementation in mind for this functionality?

void ReceiveReport() {
  ble.gattServer().read(
    outputReportChar.getValueHandle(),
    (uint8_t*)outputReport,
    (uint16_t*)outputReportLength
  );
}

Incompatible and not pairable

Hello

In the arduino IDE 1.8.13 the examples are shown as "INCOMPATIBLE" although I have selected the Arduino Nano 33 BLE.
But I can compile both examples "ble_shining_kb" and "ble_mouse" it and upload it to the Arduino Nano 33 BLE.
Then on my Android and Windows device I see for example the shining keyboard but can't connect to it.
And also the Arduino Nano 33 BLE shows an error with slowly turning its LED on and off.
I'm using the examples as is. (No modifications)

So my questions:

Why are the examples shown as incompatible although I'm using the right hardware?
What could be the reason I can't connect?

Library doesn't compile with latest Mbed board software version 1.3.0

When I try and compile the shining keyboard example on an MBED board running version 1.3.0 I get the following errors:

Error compiling for board Arduino Nano 33 BLE.

Can this library work with BLE Nano IOT?

This library looks great, the only problem I have is that I'm trying to get it to work with my Nano IOT which uses the SAMD (32-bit ARM Cortex) with a NinaW102.

What would it take to get it working with this board?

USBKeyboard influencing BLE?

Hello

I have a small arduino sketch for the Arduino Nano 33 BLE.
firmware.zip

Board Library:

Arduino Mbed OS Nano Boards v3.1.1
Libraries:
ArduinoBLE v1.3.1
Mbed BLE HID v1.3.0 or v1.2.0 (same problem with both)

I try to mix BLE functionality with the USBKeyboard.
Both individually work fine.
But as soon as I try to use both it still compiles but the Arduino crashes:
LED no longer blinking and BLE device no longer discoverable.

Is it possible that the USBKeyboard influences BLE?

State of the project?

Hi there, I'm just wondering what the state of this repo is? (abandoned, forgotten about, original author doesn't have enough time, etc). I saw the deprecation notice on the readme but can't see any information about why, so some info on that would also be great

I'm needing to use an Arduino Nano BLE as a keyboard for a year-long research project, so if someone can update me on current issues/problems or why the project was deprecated, that would be amazing. I have a fair amount of time to dedicate to making this a working interface and would love to do so, but don't really want to go in blind unless I have to.

Thanks!

Pairing can't complete for board definition 2.2.0

When using the Arduino Mbed OS Nano Boards board definition with version 2.2.0 the initial pairing request fails indicating that the passphrase was wrong.

2.0.0 appears to work.

Pairing failed

I uploaded ble_shining_kb to NANO 33 BLE and tried to pair with many Android , iOS phones and PCs but always I got error in paring.!!!!!

HID connection fails to pair with iOS

Hi, I have been trying to use the shining keyboard example on iOS but failed to. The pairing with my iPhone or iPad breaks very soon. I read a few documents from Apple, wondering if it's because the transmission is not encrypted. Also when I use LightBlue to test on the shining keyboard, the pairing breaks, too, and LightBlue reported error: the data is staled. If would be great if you can look into it!

Shining Keyboard - Android using Lightblue - says it needs a PIN

This is a lack of knowledge about BLE and Bluetooth -- I will admit that up front.
Got a Arduino 33 BLE -- Loaded Shining Keyboard

I see it on the LightBlue App -- ask to connect -- it starts

I get a pairing bubble on the screen -- then a quick bubble saying it needs a PIN.

in the Sketch -- how do you supply a PIN ??

thanks in advance for any help

Need to pair every time

I could pair ble Shining Keyboard after downgrading the Arduino Mbed OS Nano Boards to the 2.1.0 version.

My issue is How can I make the Nano board memorize that it has been paired with other BLE devices before and connect automatically.

Few problems.

I was able to run this library on Nano 33 ble with Mbed OS 2.1 and mbed-ble-hid 1.2 but there were few problems (tested on windows 10 as bt joystick):

It worked only after pairing. When disconnected it would not connect again, only constantly connecting and disconnecting every 1s
I tried to use it with: https://github.com/arduino-libraries/MadgwickAHRS, after upload the arduino hangs and windows won't recognize it any more.

Things I would love to see added:

more axis (6 is needed for OpenTrack https://github.com/opentrack/opentrack/releases)
16bit axis resolution

Thank you for your work so far, I hope that this project gets an update soon because it's awesome.

cannot work with 16-bit hid descriptor

Hi, I've tried to modified the hid_report_map in HIDGamepadService.cpp to 16-bit version as following.

// Report Map with two joysticks for Android
static uint8_t hid_report_map[] =
{
  USAGE_PAGE(1),      0x01,       // Usage Page (Generic Desktop)
  USAGE(1),           0x05,       // Usage (Game Pad)
  COLLECTION(1),      0x01,       // Collection (Application)
      // Buttons
      USAGE_PAGE(1),      0x09,       // Usage Page (Buttons)
      USAGE_MINIMUM(1),   0x01,       // Usage Minimum (1)
      USAGE_MAXIMUM(1),   0x0c,       // Usage Maximum (12)
      LOGICAL_MINIMUM(1), 0x00,       // Logical Minimum (0)
      LOGICAL_MAXIMUM(1), 0x01,       // Logical Maximum (1)
      REPORT_COUNT(1),    0x0c,       // Report Count (12)
      REPORT_SIZE(1),     0x01,       // Report Size (1)
      INPUT(1),           0x02,       // Input (Data, Variable, Absolute)
      // (padding)
      REPORT_COUNT(1),    0x01,       // Report Count (1)
      REPORT_SIZE(1),     0x04,       // Report Size (4)
      INPUT(1),           0x01,       // Input (Constant) for padding
      // joysticks
      USAGE_PAGE(1),      0x01,       // Usage Page (Generic Desktop)
      USAGE(1),           0x01,       // Usage (Pointer)
      LOGICAL_MINIMUM(2), 0x01, 0x80,       // Logical Minimum (-32767)
      LOGICAL_MAXIMUM(2), 0xFF, 0x7F,       // Logical Maximum (32767)
      REPORT_SIZE(1),     0x10,       // Report Size (16)
      REPORT_COUNT(1),    0x04,       // Report Count (4)
      COLLECTION(1),      0x00,       // Collection (Physical)
        USAGE(1),           0x30,       // Usage (X)
        USAGE(1),           0x31,       // Usage (Y)
        USAGE(1),           0x32,       // Usage (Z)
        USAGE(1),           0x35,       // Usage (Rz)
        INPUT(1),           0x02,       // Input (Data, Variable, Absolute)
    END_COLLECTION(0),              // End Collection (Physical)
  END_COLLECTION(0),              // End Collection (Application)
};

The motion function was changed to following:

void HIDGamepadService::motion(float fx, float fy, float fz, float frz) {
  uint16_t x = static_cast<int>(0x10000 + fx * 0x7fff) & 0xffff;
  uint16_t y = static_cast<int>(0x10000 + fy * 0x7fff) & 0xffff;
  uint16_t z = static_cast<int>(0x10000 + fz * 0x7fff) & 0xffff;
  uint16_t rz = static_cast<int>(0x10000 + frz * 0x7fff) & 0xffff;
  hid_input_report.x_l = (uint8_t)(x & 0x00FF);   // lower 8-bit
  hid_input_report.x_h = (uint8_t)(x>>8);   // higher 8-bit
  hid_input_report.y_l = (uint8_t)(y & 0x00FF);;
  hid_input_report.y_h = (uint8_t)(y>>8);;
  hid_input_report.z_l = (uint8_t)(z & 0x00FF);;
  hid_input_report.z_h = (uint8_t)(z>>8);;
  hid_input_report.rz_l = (uint8_t)(rz & 0x00FF);;
  hid_input_report.rz_h = (uint8_t)(rz>>8);;
}

Compilation and flashing on Arduino Nano Ble 33 was successful. On Windows it reported

This device cannot start. (Code 10) 
 Report was not byte aligned.

I googled around and found out that Mbed should support 16-bit HID (https://os.mbed.com/questions/1318/16-bit-values-for-a-joystick/). The original 8-bit version worked perfectly.

What might go wrong here? Thanks.

Compilation errors using Platformio's IDE (Visual Studio Code)

Hi. Just to note:
I tried to compile an empty project (just libraries) in VisualStudio Code and PlatformIO's IDE plugin. Previously, I downloaded and installed mbed-ble-hid using the builtin library manager. Then I came into some compilation errors and warnings at Mbed_BLE_HID.cpp.

The issue

PlatformIO's library manager seems to download an outdated version.

The workarround

I downloaded a fresh copy from this repository (master branch) to overwrite PlatformIO's files. Now, there are no compilation errors, but warnings:
