WebXR broken
So sometimes I see this update notification in my Hololens 2 device, and as a nice user I do it. And usually this is when things start to stop working as they were. Today it's about WebXR samples that do not work anymore for immersive-ar sessions or immersive-vr sessions. According to this post it's been broken for some long time, and it's probably related to some Microsoft Edge update. The error in the developer console of Edge has no details, it just says "XR Session creation failed: the specified session configuration is not supported." Any MVP feedback on this would be very much appreciated please.SolvedkhelkunMar 11, 2024Copper Contributor632Views0likes2CommentsUnity Development console cannot be disabled after deployed to Hololen2
The unity development console cannot be disabled. I have disabled development build and alway build in a release mode, but there is always a warning window on screen (Left-lower corner). The warnings are mainly about two thing: 1 the first is the a Unity connection TIME OUT WARNING (i guess it is trying to connect to a unity server or something), 2 the second warning is about the MRTK RIgiHand prefab: Non-convex MeshCollider with non-kinematic Rigidbody is no longer supported in Unity 5. Now my project is on MRTK2.6.2, and my unity version is 2019.4.32 (plasticSCM enabled). Anyone who can help me out of this nightmare....

Mesh App not working
Hi guys, I'm facing an issue of not being able to connect to the server when loading up the Microsoft Mesh app. The message shows "Failed to connect to server". Things I've tried: - Changed the internet connection to a different wifi and phone hotspot - Reinstalled the Mesh app - Windows Update for the Hololens 2 - Factory Reset, logged in with a new user and attempted to start the app None of it worked, and the same error message persisted. Is anyone facing the same issue? Could it be that Microsoft stopped managing the server for the app? Any help is much appreciated. Thank you!

I want to stream the camera feed from a Tello drone to HoloLens
Hello, I am using the following tools: TelloforUnity MRTK v1.0.2104.3 Beta Unity 2019.4.28f1 I want to be able to see the drone's camera feed on hololens. Using only TelloforUnity I am able to see the camera feed on Unity when I start the Scene, but when I try to launch the project to Hololens all I am able to see is a white screen in the area where the video should have played. For anyone who is familiar with TelloforUnity, I created a new project, added the MRTK and I added the TelloVideo to my scene. The video works fine in Unity but not on Hololens. Any Ideas how to fix this issue or how to stream a video to Hololens?SolvedChrisstyllJul 05, 2021Copper Contributor3.5KViews0likes6Comments
Hololens 2 App Installer Gone After Factory Reset
Hey all, I had an issue with my Hololens 2 so I ended up having to conduct a factory reset to attempt to get rid of the problem. However, the factory reset cleared out my app installer so it is now no longer on the device. I need to be able to use the app installer for the method of pushing out apps that I have been using. Has anybody else had this issue and does anybody know of a way to fix this?SolvedacarruthJun 09, 2021Copper Contributor1.1KViews0likes3Comments
HoloLens 2 Static IP without WiFi
I have a situation where I need to set a static IP address for a HoloLens 2 for a network that I am wired to through an Ethernet to USB-C dongle. The network is not using DHCP. The HoloLens 2 is provisioned to be an offline secure HoloLens (https://docs.microsoft.com/en-us/hololens/hololens-common-scenarios-offline-secure), so there is never the option of connecting to the target network wirelessly. I can only find options to set static IPs for the HoloLenses through the device portal if the network is available wirelessly. Even the Ethernet IP configuration settings are tied to specific network profiles and these profiles only show up for wireless networks. Any help here would be greatly appreciated, thanks!SolvedryanpetersonApr 21, 2021Copper Contributor2.1KViews0likes2Commentsmy deployed Appfolder is disappeared

MRTK Question: How to end a grab interaction via code?
I've been searching through the documentation and experimenting with several approaches, but I haven't been able to find an easy way to accomplish this. Say you have a cube with all of the script components attached to allow the user to grab the cube with either hand and move it around (Box Collider, NearInteractionGrabbable, Object Manipulator). How would you go about forcing the user to let go via code? Let's assume you've set a new Vector3 to the transform position on the cube to teleport the cube back to its starting location. How do you properly end the grab? What happens is that after changing the cube's position in code it flys back into the user's pinched fingers like they have Jedi powers I've tried two approaches so far to force the hand tracking to just let it go: Disabling the NearInteractionGrabbable and Object Manipulator script components on the cube and then re-enabling them. Changing the Manipulation Type property on the Object Manipulator to none (0). The problem is, the moment you either re-enable them or set the ManipulationType back to One and Two Handed... Force powers kick in and the cube flys back into your fingers. I'm assuming this is because both the disabling/re-enabling or setting to none/setting back to both hands is occuring within the same frame. So, the next thing I'm going to try is creating an action queue so that the re-enablement step (or setting ManipulationType back to both hands) occurs in the next frame. Any thoughts though? Is there some simple release() method that I'm overlooking?SolvedDeletedMar 26, 20211.2KViews0likes1Comment

Has anyone run into this? The microphone on my HoloLens 2 stopped working. Speech recognition is on. In the microphone settings, the mic is on and every app is enabled to use it. On the start menu, I can clearly see that it's picking up my audio. The volume level pick-up indicator in the icon responds to sound that it picks up... but, the microphone isn't working. Not just speech recognition, but even if I record a video - no audio from the mic. Or if I launch the voice recorder app... nothing is recorded. All OS and app updates are installed. I've powered it off and booted back up. Tried turning the mic off and rebooting (then turning it back on), etc. etc. I'm hesitant to factory reset the device because the mic is used during calibration/initial setup (if I recall).SolvedDeletedMar 02, 20212.6KViews0likes2Comments
