  [Puck.js a766]# info E5:DD:7B:99:A7:66
  Device E5:DD:7B:99:A7:66
  	Name: Puck.js a766
  	Alias: Puck.js a766
  	Paired: yes
  	Trusted: yes
  	Blocked: no
  	Connected: yes
  	LegacyPairing: no
  

  still doesnt work.
  What confuses me is that I can connect using EspruinoHub and send code to the device so I know that the Raspberry Pi is supporting BLE but it doesnt seem to support HID.
  Does anyone know why?

  replacing tap with

  NRF.sendHIDReport([2,0,4], function() {
    NRF.sendHIDReport([0,0,0]);
  });
  

  results in the same error. so probably not ble_hid_keyboard issue.

  One additional piece of info. I tested this while connected bluetooth to my mac, everything worked without error. This only occurs when puck is connected to raspberry pi.
  I also used a much simpler code

  var kb = require("ble_hid_keyboard");
  NRF.setServices(undefined, { hid : kb.report });
  
  function btnPressed() {
    // Send 'a'
    kb.tap(kb.KEY.A, 0, function() {
      // Followed by capital 'A'
      kb.tap(kb.KEY.A, kb.MODIFY.SHIFT);
    });
  }
  
  // trigger btnPressed whenever the button is pressed
  setWatch(btnPressed, BTN, {edge:"rising",repeat:true,debounce:50})­;
  

  got the exact same error.
  there is something wrong with ble_hid_keyboard on the raspberry pi.

  Sorry for this newbie question, first day playing with this.
  Everything is latest. Have EspruinoHub started in systemctl.
  I can connect to the raspberrypi EspruinoHub ide, connect to Puck and upload code.
  Puck firmware 2v00
  Found some code in tutorials and hacked it together. All I want to achieve is to have a button press result in a keyboard type the letter p

  After sending the code I disconnect and reconnect
  Click on the puck and console says

  Uncaught Error: Got BLE error 0x8 (INVALID_STATE)
   at line 1 col 104
  ...0,0,0],function(){a&&a()})})
                                ^
  in function "tap" called from line 6 col 36
      kb.tap(kb.KEY.P, 0,function(){});
  
  in function called from system
  >
  

  If I click the puck again I get

  Click 2
  

  Here is the full code:

  
  var kb = require("ble_hid_keyboard");
  NRF.setServices(undefined, { hid : kb.report });
  
  var clickcount = 0;
  var clickevent = null;
  
  
  setWatch((e) => {
    clickcount++;
    if (clickevent !== null) clearTimeout(clickevent);
  
    if (clickcount === 1) {
      setLEDS(false, true, false);
      kb.tap(kb.KEY.P, 0,function(){});
    } else if (clickcount === 2) {
      setLEDS(true, false, false);
      //kb.tap(kb.KEY.Z, 0);
    } else if (clickcount === 3) {
      setLEDS(false, false, true);
      //kb.tap(kb.KEY.S, 0);
    } else {
      setLEDS(true, true, true);
    }
  
    clickevent = setTimeout(() => {
      if (clickcount === 1) {
        console.log("Click 1");
      } else if (clickcount === 2) {
        console.log("Click 2");
  
      } else if (clickcount === 3) {
        console.log("Click 3");
  
      }
  
      clickcount = 0;
    }, 350);
  }, BTN, {
    edge: "rising",
    debounce: 50,
    repeat: true
  });
  
  setWatch((e) => {
    setLEDS(false, false, false);
    setTimeout(() => {
      clickevent = null;
    }, 400);
  }, BTN, {
    edge: "falling",
    debounce: 50,
    repeat: true
  });
  
  const setLEDS = (LED1on, LED2on, LED3on) => {
    LED1.reset();
    LED2.reset();
    LED3.reset();
  
    if (LED1on) LED1.set();
    if (LED2on) LED2.set();
    if (LED3on) LED3.set();
  };
  
  

  Thank you for helping me. I'm totally confused.
