    @Jean-Philippe_Rey I have just updated the 2v07 release with a fix for the issue you were seeing.
    Anyone who downloads 2v07 from now on should be fine though.

    I confirm that the new release works really well! Thank you Gordon!

    it seems that some script cannot start on Pixls.js rev. 2v07 after a reboot. we encountered this problem at work and a downgrade to 2v06 fixed the problem.
    Unfortunately I cannot share the script but it does nothing special.. a few setWatch, some setInterval and that's it. Any idea?

    Welcome Christine! Good for us that you join the party!

    I suspect that the gamepad running the script above suffers from some delay between button press and actual action by the emulator running on my Android phone. The delay is in the order of hundreds of milliseconds....
    Could it be possible that it comes from the BLE connection interval? If so, is there any chance of decreasing this delay?

    BTW, here is a first picture showing my naked gamepad. The enclosure which will be 3d printed will come in the next few days

    OK I managed to solve my problem by calling NRF.sendHIDReportmanually.
    Now I have a first working gamepad implementation. Here is my script:

    var kb=require("ble_hid_keyboard");
    var keys=[0,0,0,0,0,0,0,0];
    function onInit(){
      NRF.setServices(undefined, { hid : kb.report });
      setWatch("keys[2]=kb.KEY.UP;NRF.sendHIDR­eport(keys);", BTN_UP, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[2]=0;NRF.sendHIDReport(ke­ys);", BTN_UP, {edge:"rising",repeat:true,debounce:50})­;
      setWatch("keys[3]=kb.KEY.DOWN;NRF.sendHI­DReport(keys);", BTN_DN, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[3]=0;NRF.sendHIDReport(ke­ys);", BTN_DN, {edge:"rising",repeat:true,debounce:50})­;
      setWatch("keys[4]=kb.KEY.LEFT;NRF.sendHI­DReport(keys);", BTN_LEFT, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[4]=0;NRF.sendHIDReport(ke­ys);", BTN_LEFT, {edge:"rising",repeat:true,debounce:50})­;
      setWatch("keys[5]=kb.KEY.RIGHT;NRF.sendH­IDReport(keys);", BTN_RIGHT, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[5]=0;NRF.sendHIDReport(ke­ys);", BTN_RIGHT, {edge:"rising",repeat:true,debounce:50})­;
      setWatch("keys[6]=kb.KEY.BACKSPACE;NRF.s­endHIDReport(keys);", BTN_B, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[6]=0;NRF.sendHIDReport(ke­ys);", BTN_B, {edge:"rising",repeat:true,debounce:50})­;
      setWatch("keys[7]=kb.KEY.ENTER;NRF.sendH­IDReport(keys);", BTN_A, {edge:"falling",repeat:true,debounce:50}­);
      setWatch("keys[7]=0;NRF.sendHIDReport(ke­ys);", BTN_A, {edge:"rising",repeat:true,debounce:50})­;

    Currently I only deal with 6 buttons. This is because the HID report can handle up to 6 buttons at a time.
    I will continue to work on it for some improvements and hopefully I will come back soon with some pictures and/or videos just for your curiosity and for my pleasure ;-)

    OK I get it... Well this is far to much elaborated for such a basic app like mine. However it may be something useful for the metronome app . Moreover, Bangle.js and its display would be more adapted to indicate the time signature, compared to the few LEDs on the Thingy:52 :-)

    Well it seems the limitation comes from the module itself, in particular the method tap() which sends press and release successively...

    exports.tap = function(keyCode, modifiers, callback) {
      NRF.sendHIDReport([modifiers,0,keyCode,0­,0,0,0,0], function() {
        NRF.sendHIDReport([0,0,0,0,0,0,0,0], function() {
          if (callback) callback();
