      Hi,



      I tried to implement what you showed in our App but I didn't succeed to retrieve the GattService.

      I call the DeviceInformationCustomPairing.PairAsync, the system prompt the confirm dialog, I start my Watcher :

      string selector = "(" + GattDeviceService.GetDeviceSelectorFromUuid(Constants.MIXFADER_DATA_MAIN_SERVICE_UUID) + ") AND (System.DeviceInterface.Bluetooth.DeviceAddress:=\"" + bleDeviceAddress.ToString("X") + "\")";

      _gattServiceWatcher = DeviceInformation.CreateWatcher(selector);

      And if I call to GattDeviceService.FromIdAsync(args.Id) the response is always null.

      I also tried to the GetGattService method from BluetoothLEDevice but the result is the same.


      Can you help me ?


      One more thing, I couldn't find the source code in GitHub, can you give me a link please ?


      Thanks you,

      Ludo

      Hi,

       

      Thanks for the code. 

      I've looked at it and I don't know if it is by design or not but you create multiple GattServiceWatcher. It's one of these instances which can access the GattService.

      If I change your code to only create one GattServiceWatcher, I can't access my GattService anymore :/

       

      If you want we can talk about it by mail.
