I have bought multiple Vive Trackers 2.0. It seems to track well, but I have one issue: If I leave the device just for few minutes in idle, tracker goes to sleep and it doesn't want to wake up later on. LED on the tracker becomes white. When I press the button it becomes green, but it's status doesn't change in SteamVR. If I restart SteamVR, tracker completely dissapears and I need to pair it again.
I don't use Vive controllers.
I have tried using trackers with and without USB dongle, but there is no difference in behaviour.
On all devices I have the latest firmware and I have installed latest version on SteamVR.
I also have a couple of Vive Trackers 1.0 and there is no problem with it.
