Krogenit Posted October 15, 2018 Share Posted October 15, 2018 Hello, i am getting random loss tracking. I have 3 trackers first version for full body. It happens absolutly randomly. Few days it can be fine, but anothers days again. Before tracker got tdm sync lost it jittering few seconds. All mirrors covered. Anomaly... When tracker got loss tracking i replug dongle and it works fine all session or can got loss tracking again after few hours. If i just disable and enable tracker in SteamVR menu, it can be work only ~5 minutes. This is log when i got loss tracking: 20:14:54.132 - lighthouse: LHR-19B77CDB C: Resetting tracking: no optical samples for 2003ms 20:14:54.132 - lighthouse: LHR-19B77CDB C: Dropped 33882 back-facing hits, 7 non-clustered hits during the previous tracking session 20:14:59.137 - lighthouse: LHR-19B77CDB C: Trying to start tracking from base C02EFF42: Not enough contiguous samples for a bootstrap pose 20:14:59.893 - lighthouse: LHR-19B77CDB C: tdm sync lost 20:15:04.137 - lighthouse: LHR-19B77CDB C: No optical frames in past 5 seconds 20:15:54.435 - lighthouse: LHR-19B77CDB C: tdm sync acquired 20:15:55.673 - lighthouse: LHR-19B77CDB C: ----- BOOTSTRAPPED base 335F17EB (immediate) distance 2.25m velocity 0.53m/s recorded pitch ~25.8 deg roll ~-0.1 deg ----- 2018 20:15:57.862 - lighthouse: LHR-19B77CDB C: ----- CALIBRATED base 335F17EB at pitch 25.77 deg roll -0.57 deg ----- 2018 20:15:59.160 - lighthouse: LHR-19B77CDB C: Optical frames received again...

Can it be the problem? For trackers i use PCI Usb Hub ORIENT VA-3U4PE. I also tried use another usb ports. I have WiFi router in my room, but i tried disable it during game session.

Synthesis Posted October 15, 2018 Share Posted October 15, 2018 Do you know if it's the same tracker every time? It could be an issue with the dongle, if so. Another possibility is that it's being occluded by your body enough that neither base station can see it.Thanks, -John C Link to comment Share on other sites More sharing options...
HackPerception Posted October 15, 2018 Share Posted October 15, 2018 , in addition to the above post; are you putting all of the dongles on the same hub in close proximity to each other? The reason they come with cradles is that you can't have powerful BT transcievers in close proximity next to each other without them causing co-channel interference. Does the behavior happen when you add the cradles back into the system to separate out the transcievers? This would be my best guess as they're all using the same common Bluetooth frequency.

Krogenit Posted October 16, 2018 Author Share Posted October 16, 2018 It isn't the same tracker. It can be feet or hip. I know, if i occluded by hand, tracker got loss tracking, but in my situation tracker doesn't start tracking until i replug dongle. Link to comment Share on other sites More sharing options...
Krogenit Posted October 16, 2018 Author Share Posted October 16, 2018 , i think it isn't close to each other. Also i have a question. When i started SteamVR and enabled trackers, two of three trackers (one on feet and one on hip) after ~5 minutes stop tracking and after a few minutes start tracking again. Is that normal? Looks like first initialization. It happens every time. I still testing, maybe those two trackers have bad dongles. Does tracker connect to random dongle?
