Using Puck as a single button keyboard

What happens when you type save() that means that you need to re-update the firmware? Updating the firmware won't actually delete your saved code so I wonder what's happening.

Try uploading this code:

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

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

from the right-hand side, and then type save() on the left-hand side. I'm sure this works just fine on 1v92.
