Tracking Issues with 5 vive trackers

[iig_epfl]

Hi,

I have some tracking issues with the vive trackers but only when I reach 5 trackers. Indeed, I have tried with 4 trackers I did not see any tracking issues. But when I add a fifth tracker, all the trackers become instable and have some jitters. The fifth one is the worst. I don't know why . I have tried with different dongles and trackers since I have 13 vive trackers in the lab. and different computers ( Titan X and 1080Ti) I cannot have more than 4 trackers without any issues.

You can see it in the video linked below:

If you have any idea I will be glad be cause I was trying to use these trackers to set VRIK but I cannot do it with this issue.
Best,

VibrantNebula, what do you think about this? There's not a hard limit that I know about, but could be EM interference with that many bluetooth radios in one place?

Thanks,

Happy to try and help or connect you with the right people who can help. I sent a request to view the link you've shared. Have you tried multiple dongles? Do the two computers have similar motherboards (and thus similar USB controllers)?

Hi!
Thank you to consider my request so quickly. I have a total of 13 dongles and I tried with all of them. The first computer has an ASUS Motherboard and the other one has a MSI Motherboard. It s two completly different computers ( but both work with windows 10).

I have updated all the trackers and steamVR. I do not know what to do more. I have set my lighthouse several times.
Thank you in advance.
