Puck Controlling Puck - Troubleshooting Help

Hi - this is an odd one. I get this too. It seems like you're doing everything right on the code front.

Please could you try:

      NRF.requestDevice({ filters: [{ name: 'Puck.js ....' }] }).then(function(device) {
        return device.gatt.connect();
      }).then(function(d) {
        connected = d;
        return new Promise(r => setTimeout(r,500)); //< ---------- added this delay
      }).then(function() {
        return connected.getPrimaryService("6e400001-b5a3-f393-e0a9-e50e24dcca9e");
      }).then(function(s) {
        return s.getCharacteristic("6e400002-b5a3-f393-e0a9-e50e24dcca9e");
      }).then(function(c) {
     ...

That's what worked well for me...

I'm a bit busy today but I just filed an issue for this at https://github.com/espruino/Espruino/issues/2008 and I'll try and get it fixed properly as soon as I can.
