BLE HID mouse mostly not supported on Windows 11

[yerpj]

I have experienced that almost no WIN11 PC will accept HID reports sent by Espruino with this module. If anyone found a solution, why not publishing it here? :-)

Does BLE HID Combo work? https://www.espruino.com/BLE+Keyboard#combination

[yerpj]

Yes the HID Combo seems to work reliably. Do you think there is something odd in the HID Mouse descriptor?

[gfwilliams]

Well, I guess there must be. It's possible that you could find another one somewhere that you could use, or maybe the HID combo one could be stripped down. For example you could remove these lines: https://github.com/espruino/EspruinoDocs/blob/master/modules/ble_hid_combo.js#L76-L98

I just did this and tested:

exports = {};

exports.report = new Uint8Array([
    0x05, 0x01,                    // USAGE_PAGE (Generic Desktop)
    0x09, 0x02,                    // USAGE (Mouse)

    0x75, 0x03,                    //     REPORT_SIZE (3)
    0x81, 0x03,                    //     INPUT (Cnst,Var,Abs)

    0x15, 0x81,                    //     LOGICAL_MINIMUM (-127)
    0x25, 0x7f,                    //     LOGICAL_MAXIMUM (127)

    0x81, 0x06,                    //     INPUT (Data,Var,Rel)
    0x05, 0x0c,                    //     USAGE_PAGE (Consumer Devices)

    0x81, 0x06,                    //     INPUT (Data,Var,Rel)
    0xc0,                          //     END_COLLECTION
    0xc0,                          // END_COLLECTION
]);

exports.BUTTONS = {
  NONE : 0,
  LEFT : 1,
  RIGHT : 2,
  MIDDLE : 4
};
exports.send = function(x,y,b, callback) {
  NRF.sendHIDReport([1, b, x, y, 0/*wheel*/, 0/*hwheel*/], function() {
    if (callback) callback(); 
  });
};

///  testing!

setWatch(function() {
  Terminal.setConsole();
  print("Sending");
  mouse.send(10,10,0);
},BTN,{repeat:1});

var mouse = exports;
NRF.setServices(undefined, { hid : mouse.report });
NRF.setAdvertising([
  {}, // include original Advertising packet
  [   // second packet containing 'appearance'
    2, 1, 6,  // standard Bluetooth flags
    3,3,0x12,0x18, // HID Service
    3,0x19,0xc1,0x03 // Appearance: 0x03C1 Keyboard
        // 0xc2,0x03 : 0x03C2 Mouse
        // 0xc3,0x03 : 0x03C3 Joystick
  ]
]);

And it seems to work. If you could confirm then I could update the module

I had to comment out line "Terminal.setConsole();" but after that, it works like a charm. Thank you @gfwilliams !

I've just pushed some changes - they're not live on the website yet though

[enaon]

I have experienced that almost no WIN11 PC will accept HID reports sent by Espruino with this module. If anyone found a solution, why not publishing it here? :-)

could it be that the win11 does not want to accept HID commands from a device that was once connected as standard BLE. ?
Maybe try changing the BT address when using HID mode, this works fine for me on win11, but I have not tested the mouse module.

[yerpj]

I did try it but it seems not to be the case. At this stage I would suspect something odd in the HID Mouse descriptor, as the HID Combo works well.
I did try to ask ChatGPT but it tells me to disable NUS service, which is not very helpful nor effective :-)
