It is with a heavy heart that we announce the closure of our Mixed Reality Tech Community. As Microsoft is no longer manufacturing and selling Microsoft HoloLens 2, and there are no further investments in new features or functionality, we will be shutting this forum down on March 1st, 2025. We want to express our deepest gratitude for your support, enthusiasm, and contributions over the years. Your passion and engagement have been the cornerstone of this community, and we are truly thankful for the vibrant discussions and knowledge sharing. While this chapter is coming to an end, our team remains available on Microsoft Q&A or via email at mshololens@microsoft.com. While the following communities are not managed by Microsoft, they contain valuable insights and expertise shared by fellow enthusiasts and experts: StackOverflow, Reddit, and HoloDevelopers Slack. Thank you once again for being a part of our journey. We look forward to seeing you in our other communities.

Hi all I hope this post can help your guys having the same problem as me. Basically, I want to share my view with Hololens 2 to a TV while I make a guides. Being more specifical, the TV is a Samsung "The Frame". So, I using the web device portal for Hololens 2 in my laptop, from the laptop to TV a HDMI cable for share the screen. The problem problem is: Are actually many issues with the "live preview" feature from device portal. When the live starts (doesn't matter if is 720p or 480p) it works fine, as soon as I open any guides training, the live mode begin to have lagging trouble. Error description: Live preview stalled duo to low bandwidth or loss of connectivity. If this problem persists, consider using a lower quality stream.Error when trying to install certificate on Hololens 2
Hello everyone! I have a problem when installing a certificate on my Hololens 2. The device shows an error with code: 0x8009310B. I have attached a link to a screenshot of this error below. Can anyone suggest what could be causing this? https://drive.google.com/file/d/1i8u7WuJE6B35VuZmZapKByXt7_ox7GJ3/view?usp=share_linkMRTK 3 Pinch Recognition On HoloLens 2
Hi everyone, this is my first time posting here. Please let me know if I messed up something in this post. I am optimizing a HoloLens 2 application developed with MRTK 3 in Unity, and I have been trying to improve the sensitivity of pinch recognition. In other words, what I wish to achieve is that the object manipulators in the application are only activated by pinching when the user’s thumb-forefinger distance becomes 0 (or at the least very close to 0). I set the pinch open threshold and the pinch closed threshold of the hands aggregator subsystem of MRTK 3 to 0.08 and 0.03, hoping that MRTK 3 will only recognize pinch in the more sensitive way mentioned above. However, the object manipulators are still activated by pinching even when the user’s thumb and forefinger are quite far away (about one half of the length of the user’s forefinger) from each other. Is this because of the hardware limitation of HoloLens 2? Is there any possibility that I can improve the pinch recognition on HoloLens 2? Big thanks in advance!114Views0likes0CommentsHololens 2 nightmare!
The device as far as I know is bricked due to a faulty update released by Microsoft. For some reason the device is not charging above 1 LED light (Even when charging it overnight). Microsoft customer care suggested to re flash the device which is a simple straight forward process but the device is nowhere the minimum 40% charge because of some restriction. Getting into EDL mode by pressing the Brightness UP + Brightness DOWN + Power button until the LED's disappear only enables me to update the driver using the device manager window. Thinking this as a bypass to the 40% charge requirement, tried connecting to the ARC software with the latest .ffu file and the recovery .ffu file (in case the process got stuck). ARC opens a page which says unable to connect to the server (which I understand) but will not let me choose the manual package file I have downloaded. The option is greyed out. Tried everything but no luck. Tried to solve this using the Windows Recovery tool which was used to recover LUMIA phones back in the day, the device does not want to connect to anything. If anyone has any ideas on solving this, I am all ears! P.S. All of this looks suspiciousUWP app network connection blocked by hololens 2 windows firewall
Hello, my UWP app, which was installed on the HoloLens, has encountered an issue and is now unable to connect to the internet.I checked the hololens diagnostic log and it stated the following event: "Windows Defender Firewall was unable to notify the user that it blocked an application from accepting incoming connections on the network. Reason: The application is non interactive Application Path:.....". My development setup includes Unity 2018.4.11f1 and Visual Studio 2019. The capability setting in AppxManifest file is: <Capabilities> <Capability Name="internetClient" /> <Capability Name="internetClientServer" /> <Capability Name="privateNetworkClientServer"/> <uap:Capability Name="documentsLibrary" /> <uap2:Capability Name="spatialPerception" /> <DeviceCapability Name="webcam" /> <DeviceCapability Name="microphone" /> </Capabilities> The application tested all OK in unity editor but when loaded to hololens it failed to establish a network connection. Does anyone has any idea why the app has been blocked by hololens firewall? Thanks987Views1like5CommentsUnity App Stuck Loading On HoloLens 2
I am following https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/unity-development-overview?tabs=arr%2CD365%2Chl2 and https://learn.microsoft.com/en-us/training/paths/beginner-hololens-2-tutorials/ to test AR on a HoloLens 2, and I go to the part where I have a Unity game with all the proper setup (ie. build settings are correct, I used Unity AR feature tool, etc.) and with 2 squares. I built the project and opened the solution, and then I set the configuration to "Release," platform to "ARM64," and set it to "Device" because I have the HoloLens directly connected to my laptop. I selected the Unity app solution and right-clicked it to "Set as Startup Project." Then, I pressed the green button next to "Device" to build and deploy it. The first time, I got prompted to enter a pin after a bit, which I did, and once the deployment was done, the app showed in the "All Apps" section, but once I clicked on it, I got a window that had a white background with a box with an X in the middle of the screen. On top, there is a blue circle with a white loading circle that was loading for forever. I tried rebuilding it multiple times, recreating the Unity project in a new project, and double-checking my Unity build settings, but those were correct. How can I fix this issue? I'm using Unity version 2022.3.20f1. Thank you, Avinash Devineni Edit: Now it started doing the environment scanning visual, but still shows a white box, although there is no blue loading circle anymore. I didn't change anything or redeploy it to the HoloLens 2, so I'm not sure why it started doing something different.308Views0likes0CommentsAs new HoloLens 2 Commercial for sale
