Connecting The HoloLens Clicker to RasPi 3 using Bluetooth LE Explorer

Hello, i'm trying to run Bluetooth Low Energy Sample (found here: Bluetooth LE) on a RasPi 3 (OS Version 10.0.16299.15). The Raspi can successfully pair with the hololens clicker at "Scenario1_Discovery" however pressing the read value button returns a protocol error. When pressing Connect at "Scenario2_Client", it shows 6 services available shown below:

Pressing "6174" showed 2 characteristics, 10916 and 10917, selecting 10917 showed a read value button:

Lastly, pressing Read Value shows "Read Failed Protocol Error". At Scenario2_Client.xaml.cs, result returns Protocol Error

GattReadResult result = await selectedCharacteristic.ReadValueAsync(BluetoothCacheMode.Uncached);
if (result.Status == GattCommunicationStatus.Success)
string formattedResult = FormatValueByPresentation(result.Value, presentationFormat);
rootPage.NotifyUser($"Read result: {formattedResult}", NotifyType.StatusMessage);
rootPage.NotifyUser($"Read failed: {result.Status}", NotifyType.ErrorMessage);
Is there any way to communicate with the HoloLens Clicker with the RasPi? What am I missing? Is it really exclusive for hololens? do we need to send a string to the clicker to get data from it? This question was already asked at IOT Forum and it was recommended that to post the question here since it involves the hololens clicker.
