Hello, I have some Vive trackers (3.0 and 2.0) with liighthouses 2.0 which I used successfully with a Vive ProEye. Now, I want to use them with a Vive Elite XR, How do I do that ? I found that it is possible to use the trackers 2 and 3 without a VR headset. So, my idea was that I could disable the ProEye, pair the trackers with a bluetooth dongle and then restart SteamVR using Vive Bussiness streaming to enable the EliteXR. Here are the instruuctions I found: You can use Vive trackers without an HMD (Head-Mounted Display) by following these steps: Shut down SteamVR: Make sure SteamVR is not running. Edit the SteamVR settings: Locate the default.vrsettings file in the SteamVR directory (usually found in Steam\steamapps\common\SteamVR\resources\settings). Open the file with a text editor and find the requireHmd key under the steamvr section. Set the value of requireHmd to false. Enable multiple drivers: In the same default.vrsettings file, add activateMultipleDrivers set to true in the steamvr section. Add a driver_null section with enable set to true. Restart SteamVR: After making these changes, restart SteamVR. Pair the trackers: Connect the Vive tracker dongles to your PC and pair the trackers. This setup allows you to use the Vive trackers for various applications without needing the full VR headset123. If you need a visual guide, there are helpful video tutorials available, such as this one on YouTube4. What do you plan to use the Vive trackers for? At some point I got one the Trackers successsfully paired with no headset, but I did not see the Lighthouses. And when Vive Businesss Streaming restarted SteamVR, the tracker diisappeared but still kepy its light green aas if it was paired. In fact, is that possible aat all to achieve what I want to do ? I remember at some point I had seen seen a kind of stick sold bby HTC which allowed to calibrate the old trackers visually with the ElireXR by moovving it around. But I can find it anywhere. Thannk you for any help or suggestion, Christian

Hello, I think I got it ! I upgraded to API Level 30 instead of 29 in Peoject settings->Abdroid and it compiled with no error: Sorry for the noise. I got confused by this Gradle thing. In fact it has never been clear to me if in Unity we have to manage Android API versions manually or if Unity was managing it automatically. Thanks for the answer ! 🙂

Sure:

Hi, I am trying to build a very simple Unity project. Unity version: 2022.3.41f1 Wave package version: 6.1.0-r8 I have properly set-it-up for Android and before importing Wave package, I have been able to build my app into an APK. Then I imported Wave as described in: Getting Started with Wave for Unity Developers - Developer Resources (vive.com) When I clic on Wave->Preference->Custom Gradle version, I get the following message: Then I clic "Configure unity environment", which got me the following window: I then clicked to import the Android manifest features. When I try to build my project, I get the following errors: Checking the license for package Android SDK Platform 30 in C:\Program Files\Unity\Hub\Editor\2022.3.41f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\licenses License for package Android SDK Platform 30 accepted.

Hello, I got it working with Vive Business Streaming along with OpenXR. I also got MR working as an app downloaded inside the Vive Elite XR using Wave VR plugin. My question is why is it not possible to compile the OpenXR version illustrated in this discussion for Android ? I am able to package it for Android, but the APP does not appear in the installed APPs if I do not use the Wave VR plugin. And I do not like the Wave VR plugin because it is not standard. It requires changing several things in the project. To add a precision: I am Using Unreal Engine 5.2.

And also that link: Unreal Plugin Getting Started — Wave VR 5.6.0 documentation (vive.com)

I found the answer at the link below: Setting Up Unreal Engine Projects for Android Development | Unreal Engine 5.2 Documentation Hope this to be usefull for other people like me who have the same issue 🙂

Hello, I just made a very simple mixed reality APP using Unreal 5.3 and the Vive Elite XR. It is just a simple cube in the middle of the room. I am streaming using Vive business Sreaming. It works well. The problem I have is when I walk, I see the cube oscillating up and down at the rythm of my steps. I understand it is created because there is a lag between the Vive sensor transmission of data and the computer generating the next image frame. It is caused by the streaming. I bet if the APP would be running inside the HMD instead of streaming from the PC I would not have this issue. When we walk in VR only (no mixed reality), this phenomenon is les observable because the VR world is not confronted with the real world. When we are in mixed reality, the realworld is instantly updated from the camera, but the VR objects are updated with a delay if we stream from the PC which creates the illusion the objects are jumping. This is a huge problem. Regards

Hello, I have on my disposition a Vive Focus 3 as well as a Vive Elite XR. I want to package my project to run inside yje HMD (Android platform) instead of streaming from the PC. How to I do that ? I have experienced doing that with the META Quest products. I imagine this must be similar. I just need the platform settings for it to work with the HTC vive products. Is there any tutorial or documentation on it ? Thanks and regards !
