I have 8 Vive trackers (2018 and up model) and 4 lighthouse base stations version 2.0. They all track very well along with a Valve Index. Suddenly during use tonight my Vive Trackers started fading in and out of tracking in the SteamVR window. This has not happened before to me. Further, some were even turning back into grey hexagons again as if they were just powering on. Others still were just fading in and out saying they could not be tracked when they were all clearly in the view of the 4 lighthouse base stations. I shut them all off and restarted SteamVR and when I turned each tracker back on they would take 30 seconds or more to appear in SteamVR which has never happened before. They normally appear in SteamVR after being turned on in just a few seconds and start tracking a few seconds after that. Further only 6 of the 8 appeared despite all 8 having green connection lights no matter how long I waited. It seemed very chunky and slow despite CPU, GPU and memory usage being in the low %. All 8 trackers had green lights the entire time, but when I would shut down SteamVR, 3 would remain on and green. When I shutdown SteamVR before, all trackers immediately shut down. I rebooted my PC several times, and again same issue. This never happened until tonight. I cannot tell of this is due to interference from somewhere new, a buggy SteamVR update that I recall happened at some point tonight or maybe the batteries in the trackers need to be above 80% as they were on for about 60 minutes from a full charge at this point and the ones that did connect stated 3 out of 4 battery bars? Are others having sudden issues connecting to their Vive Trackers too? Anyone have an idea of what may be going on? Again they were all working perfectly fine for 60 mins tonight and over the past few weeks with no issues like this at all. Thanks for any tips.
