  it looks like async/await is not supported, is it?

• I demand BangleJS3!

  Hi all, JS2 is very good. What is important for me:
  1 - Sunlight readability
  2 - Waterproofing
  3 - Good GPS

  Nice to have:
  4 - larger screen size.
  5 - more buttons
  6 - good gold plated contacts, they also can be on a side, so they do not touch skin.
  7 - rugged body / pins.

  Hi.
  I've created Android app that serves Location and Navigation service, Device info, and Time service (standard GATT profiles). LNS has 3 characteristics.
  Currently in Bangle JS2 client app I can subscribe to one service, one characteristic.

  function connection_setup() {
    NRF.requestDevice({filters:[{namePrefix:­"Pixel 4a"}]}).then(function(d) {
      device = d;
      console.log("Found device: "+d.name);
      E.showMessage("Found device"+d.name);
      return device.gatt.connect();
    }).then(function(ga) {
      gatt = ga;
      E.showMessage("Connected");
      console.log("Connected");
      lastReceivedTime = new Date();
      return gatt.getPrimaryService("1819"); //How to get another services here?
    }).then(function(s) {
      service = s;
      return service.getCharacteristic("2a67"); //How to get other characteristics here?
    }).then(function(c) {
      characteristic = c;
      characteristic.on('characteristicvaluech­anged', (event)=>updateSpeed(event));
      return characteristic.startNotifications();
    }).then(function() {
      console.log("Notifications subsribed");
      E.showMessage("Notifications subsribed");
    }).catch(function(e) {
      E.showMessage(e.toString(), "ERROR");
      console.log(e);
    });
  }
  

  How to subscribe for LNS multiple characteristics, and to Time service, and also query Device info? Each .then() has only one return, I am not getting how to fork or chain it.

  You are SUPER!

  Great! The warning gone with the workaround.
  But the ERR 0x7 is still there.

  Hi Gordon,
  I've loaded the cutting edge build 2v14.64.
  Now it shows the devices but fails to device.gatt.connect();
  It shows:

  var device;
  var gatt;
  
  NRF.requestDevice({filters:[{services:["­1805"]}]}).then(function(d) {
      device = d;
      console.log("Found device: "+d.name);
      return device.gatt.connect();
    }).then(function(ga) {
      gatt = ga;
      console.log("Connected");
    }).catch(function(e) {
      console.log(e);
    });
  

  WARNING: Unknown phy "undefined"
  Found device: Pixel 4a
  ERR 0x7 (INVALID_PARAM)

  I am confused. Does it mean that "auto-confirmation" is implemented starting with build 2v14.52 and you, for time being, just do not want to change it to the "manual confirmation"?
  I am Ok with that. It will be much better than without confirmation at all. :)
