  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.
