2 issues with Vive Focus 3 and eye-tracking on PC


Recommended Posts



I've recently got Focus 3 but could not eye-tracking working. I have the headset and PC (Win11) connected via a network such that Vive Business Streaming (1.11.8c) running on them. This connection work and I can run PC VR apps in the headset. I also installed Stream VR (1.26.7) and Vive Console for Stream VR ( Vive Console does not see the headset at all, giving a red message (the headset can not be detected...) all the time, even when Vive Business actually streams to the headset.

Next, I tried to make eye-tracking working by running SRanipal (, since I have a test Unity app that works via TobiiXR and SRanipal. I am able to calibrate eye-tracker in the headset settings and I see that SRAnipal tray icon changes from the black to blue (see the attachment). However, the icon never becomes green (I suppose that the green indicates successful tracking) and my test Unity app never receives gaze samples. Am I right that this issue is related to SRanipal. How can I make it working?



The second issue is instability of Vive Business Streaming's connection. Very often, VBS in my headset says that it just can not find a streaming PC. Eventually, after some random time, the headset connects to PC and VBS starts working. This instability is very annoying and it happens almost every time when I turn on the headset and VBS. Interestingly, that once the connection is established, it never breaks. I double-checked my network/firewall settings on PC and router, as well as network signal quality- everything looks normal. When connection fails, the headset and PC can still ping each other in the network. Can you give me an advice how to make the connection more stable?


Thank you in advance!
