  • This is an updated function. Added 2 lines to the 2nd catch. It handles the disconnected case better. You'll still get a red blink because the write fails. But on next press it will try and reconnect and you'll be back in business.

    // Function to call 'toggle' on the other Puck
    function sendToggle() {
      if (!busy) {
        busy = true;
        if (!connected) {
          NRF.requestDevice({ filters: [{ name: 'Puck.js d958' }] }).then(function(device) {
            return device.gatt.connect();
          }).then(function(d) {
            connected = d;
            return d.getPrimaryService("6e400001-b5a3-f393-­e0a9-e50e24dcca9e");
          }).then(function(s) {
            return s.getCharacteristic("6e400002-b5a3-f393-­e0a9-e50e24dcca9e");
          }).then(function(c) {
            txCharacteristic = c;
            busy = false;
            // Now actually send the toggle command
            sendToggle();
          }).catch(function() {

            connected=false;
            digitalPulse(LED1, 1, 500); // light red if we had a problem
