Using Puck as a single button keyboard

Ok after un-pairing and re-pairing I get the same issue with the error: "Try connecting your device again". But now with the code from your comment #41.

Edit:
Something is causing an error on the puckjs because I have it blinking a light to show that its running and this stops as soon as I try to pair.

var kb = require("ble_hid_keyboard");
var on = false;

function onInit() {
  NRF.setServices(undefined, { hid : kb.report });
  setWatch(btnPressed, BTN, {edge:"rising",repeat:true,debounce:50});
  flashLED();
}

function btnPressed() {
  kb.tap(kb.KEY['c'], 0);
}

var flashLED = function() {
  on = !on;
  LED1.write(on);
  var interval;
  if(on) {
    interval = 5;
  } else {
    interval = 5000;
  }
  setTimeout(flashLED, interval);
};

It doesn't seem to be code specific either because I tried pairing with no code running.
And again rolling back to 1v91 and there are no pairing issues.
