Please help this newbie. Puck.js on Raspberry Pi 3B

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.

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.

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.

I believe the issue is just that when you connect to Puck.js from the EspruinoHub IDE on the Raspberry Pi, it is connecting to just the Bluetooth Serial port. It's not connecting as a Keyboard device, so when you go to send keypresses the command fails.

If you don't connect from the EspruinoHub IDE and instead connect via the Raspberry Pi's Bluetooth GUI, it'll might start treating it as a keyboard and it'd work fine.

However looking at this post from a year ago, it's possible the Raspberry Pi doesn't support Bluetooth HID devices at all: https://www.raspberrypi.org/forums/viewtopic.php?t=176808

Things may have changed in the last year though.

[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?
