    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,

    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.
