HMD Lost Tracking Detection not working in LBE Mode

[EashBala]

Hi,

I am trying to have it so the headset (Vive Focus 3) will tell the game (Unreal Engine 4) when it loses tracking, so I can provide a warning to the players that tracking has been lost and they must stay put. However, I noticed that the code to detect lost tracking does not work if the headset is in LBE Mode. I tried the same code provided here: https://hub.vive.com/storage/docs/en-us/WVR_GetDeviceErrorState.html#_CPPv440WVR_DeviceErrorStatus_DeviceLostTracking on a headset with no LBE Features enabled and it works, after 5-10 seconds of forcing a lost tracking. Would anyone know why the code works on a headset with no LBE features but not an headset with those features enabled?

Howdy,
We're going to take a look at this and get some feedback from the devs. thanks for reporting this!

Hey, It turns out that when we switched over to the new device management tool instead of VBC, the lost detection event works now with the LBE features.
