Headset not detected

Gaming and Visualization Technologies XR – VR/AR/MR CloudXR (VR and AR Streaming)

Hello, I’ve just begun beta-testing CloudXR, and installed it on my system (MS-Windows, RTX-2060) this evening. As the subject says, my primary issue is that the “CXR” headset (and controllers) never appear in the SteamVR control panel, and instead it reports that “Headset Not Detected” message. I tried doing “Reset Headset” and stopping and starting “SteamVR”, but still the same.

I did look at the pinned forum topic on “simplified” troubleshooting – though the length seems more like it’s very thorough rather than simplified, and I didn’t see the answer to my issue there.

I did run “vrpathreg.exe” and that confirms that the CloudXRRemoteHMD is available as an external driver – I’ll past that output below.

I’m running “CloudXRServerSample.exe” as administrator, and at least once when I ran “CloudXRClientSample.exe” I got the image shown in the “simplified” troubleshooting instructions with a double view into a dark world and two Meta controllers. But the world view and controllers didn’t move to any inputs. (And now I can’t even get that to happen again.)

I did unplug my Vive HMD before doing this – since the idea is that I’d be remotely running to a Quest or something, so I shouldn’t need the wired HMD. But maybe that’s wrong. (And this now raises a new question in my head – do I need to download an app in the Meta Store on the Quest before any of this will work?)

Thanks for the help, “vrpathreg” output follows,
Bill

Hi there!

Yeah, I understand that it doesn’t seem simlified, but CloudXR is not a retail tool for quickly and easily streaming from a gaming computer to a VR headset on a LAN, like Virtual Desktop. It is an SDK for building XR streaming clients and deploying multi-computer XR streaming architectures. There is, alas, very little simple about this.

I recommend you spend some time stepping through the debug guide, which is probably misnamed. It’s really a tutorial to get folks from never-having-used-CloudXR to streaming on a LAN. And it also introduces a lot of tools, terminology, and essential knowledge.

To respond to a few of your specific points:

  • It is correct to disconnect your VIVE.
  • The CloudXR HMD will not appear in SteamVR until a client connects; “headset not found” what SteamVR will show when it is waiting for a connection. How to tell if your server is working is addressed in the debug guide.
  • CloudXRServerSample is an alternative server to SteamVR for testing. You cannot run both of them at the same time.
  • You will have to build and side-load an APK if you want to use Meta Quest as a client.

Great, thanks for the info. I’ll try going through the help posting with that information in mind.

One followup on the Quest – is there already an APK, or are you saying I’d have to write the Android program and then load that APK onto the Quest?

Thanks again.

Included with the CloudXR-SDK is an Android studio project for a Quest sample application.

I suggest you start here, with the Android sample client requirements, as it has some up-to-date guidance:
https://docs.nvidia.com/cloudxr-sdk/usr_guide/system_requirements.html#android-sample-clients

Full build instructions are here:

A quick note:

I discovered a critical typo in the guide related to running the client and server on the same computer, which may have exacerbated the “headset not detected” issue. See here:
