Trying to get my device working...

Hi @Gordon,
Tried your suggestions above to no avail. I have a nice test bench using two puck-js devices as follows: set up one using the LBS (LightButtonService) I published several months ago. Set up the other to find and set the LED. Here's the code; I've verified that the LBS is still working as advertised (pun intended).

I get either no service found or an IDE disconnect, sometimes requiring I pull the battery to reset the (finder) device.

Let me know if you get the same/different results, THANKS!

LBS code:

NRF.setAdvertising({}, {name: "Nordic_Blinky"});

pinMode(D5, "output");
pinMode(D6, "output");
pinMode(D7, "output");
pinMode(D31, "output");
pinMode(D16, "input");

NRF.setServices({
  "00001523-1212-EFDE-1523-785FEABCD123" : {
    "00001524-1212-EFDE-1523-785FEABCD123" : { // button
      value : 0x00, // optional
      broadcast : false, // optional, default is false
      readable : true,   // optional, default is false
      writable : false,   // optional, default is false
      notify : true,   // optional, default is false
      indicate : false,   // optional, default is false
    },
    
    "00001525-1212-EFDE-1523-785FEABCD123" : { // LED
      value : 0x00, // optional
      broadcast : false, // optional, default is false
      readable : true,   // optional, default is false
      writable : true,   // optional, default is false
      notify : false,   // optional, default is false
      indicate : false,   // optional, default is false
            onWrite : function(evt) {
        digitalWrite([D5,D6,D31,D7], evt.data[0]);
            }
    }
    
  }
});

setWatch(function() {
  NRF.updateServices({
  "00001523-1212-EFDE-1523-785FEABCD123" : {
    "00001524-1212-EFDE-1523-785FEABCD123" : {
      value : 0x01,
      notify: true
    }
  }
});
}, D16, {edge:"rising", debounce:50, repeat:true});


setWatch(function() {
  NRF.updateServices({
  "00001523-1212-EFDE-1523-785FEABCD123" : {
    "00001524-1212-EFDE-1523-785FEABCD123" : {
      value : 0x00,
      notify: true
    }
  }
});
}, D16, {edge:"falling", debounce:50, repeat:true});

Finder code:

var devices;

NRF.findDevices(function(devices) {
  if (devices.length < 1) throw new Error("Nothing found!");
  devices[0].gatt.connect().then(function(g) {
    gatt = g;
    return gatt.getPrimaryService("00001523-1212-EFDE-1523-785FEABCD123");
  }).then(function(service) {
    return service.getCharacteristic("00001525-1212-EFDE-1523-785FEABCD123");
  }).then(function(characteristic) {
    characteristic.writeValue( [0xff] );
  }).then(function() {
    gatt.disconnect();
    console.log("Done!");
  });
}, 4000);
