Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

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.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. 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. And always feel free to hit us up on Twitter @MxdRealityDev.

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.
