Hello everyone.

There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.

If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

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($"Read result: {formattedResult}", NotifyType.StatusMessage);
}
else
{
rootPage.NotifyUser($"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.
