Live preview stalled duo to low bandwidth or loss of connectivity.
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_link
Hololens 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 suspicious
Unity App Stuck Loading On HoloLens 2
I am following this document and this tutorial 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.Please share your experience with tethered cellular
We've recently added a new docs page to include more information on connecting HoloLens to cellular networks. You can find it at https://aka.ms/HL5G. While hotspot / WiFi is sufficient for most use cases, there are still times when tethering provides some benefit (for example ultra low latency or Azure Remote Rendering). Though we're unable to provide a curated list of cellular devices that are compatible with HoloLens 2, we're hoping folks in our community can share your own experience with the devices that have worked for you. Thanks in advance for sharing, and thank you for being part of the community!
Hand Gestures not working on HoloLens 2
Hi folks, I created an MR application on HoloLens 2 and was working fine. One day, the device went to sleep when the application was running and when i turned on the device again, the hand gestures (scaling, positioning and rotating) are not working at all. And also, the issue occurred on every app i made with Unity before. I did factory reset on the device and even then its not solved. I have two HoloLens with me and both of them are having this hand gestures issue now. I'm in a desperate situation. Please help me out with a solution for this...
HoloLens2 Microphone Not Recognizing Speech Commands
Hololens is picking up my audio, but none of my voice commands are registering. The audio picked up from the microphone is faint too. All OS and app updates are already installed. Device has been powered off and booted back up. Tried factory resetting device too. Not sure how to fix issue. Currently developing in Unity.Sending HoloLens 2 video stream through Roboflow API
Hello everyone, I’m currently working on a mixed reality project for the HoloLens 2, which involves the use of a computer vision model for the recognition of some shop-floor equipment and parts. My team has trained this model in Roboflow, using the data we’ve collected in a factory. However, we’re not sure how to integrate this model to the HoloLens. We thought it could be a good idea to access the HoloLens’ video stream in order to send it to the CV model through the Roboflow API, and get the result back, in runtime. So we’re looking at Microsoft’s CV samples for the HoloLens 2, which includes a “StreamRecorder” sample. However, this sample saves the stream in a raw format, which would need to be converted before sending it to the CV model. We’re actually not even sure if using this sample as a basis is the best way to do what we want, so we’re a bit lost at the moment. Has anyone here tried accessing the Roboflow API from a HoloLens 2? How would be the best way to go about it? Thanks in advance.Objects not anchored in Hololens 2 after building from Unity
Hello all, I hope I found the right spot to put this. I am having an issue with porting one of our apps from Magic Leap 2 to Hololens 2 in Unity. After setting up MRTK into the project and hooking a few things up, I build the project for UWP and deploy to the device. When running the app, all objects in the scene move with the camera instead of staying anchored to their position. If I setup MRTK in an empty project and deploy, objects in the scene however are anchored appropriately. I am not sure what is possibly causing this, but I imagine there is some setting or error within my project. I do not have much experience with Hololens development. Things I have tried: -Disabling unnecessary DLLs from being loaded for UWP -Fixing any exceptions thrown shown in the Player Log file -Updating any conditional compilation tags so code from other platforms do not run unintentionally -Checking MRTK project/build/prefab settings against empty project that is successful Perhaps someone here is aware of what triggers this and could potentially point me in the right direction. I am using Unity 2022.3.11. Thanks in advance!
