Hi,

I am getting the following exception in the line pairedDevices.Items.Add(await BluetoothLEDevice.FromIdAsync(info.Id)); of UWP-Starter.
Exception thrown: 'System.ArgumentException' in mscorlib.ni.dll.
Thanks in advance.

    So, on modifying the code just a little bit, like this:

    BluetoothLEDevice temp = await BluetoothLEDevice.FromIdAsync(info.Id);
    pairedDevices.Items.Add(temp);

    The exception is on the line pairedDevices.Items.Add(temp);
    temp turns out to be null and the exception has a message saying "Value does not fall within the expected range"

    So, apparently you have to enable Bluetooth on PackageManifest file.

    Do this if you are using VS by by checking Bluetooth box at: "Properties"->"Application"->"Package Manifest..."->"Capabilities"->"Bluetooth".
    Works now. Thanks:-)

    That's odd, Bluetooth capabilities should already be enabled in the manifest file.


    What Visual Studio version are you using?
