Update: I had yesterday my first trackday after the issue reported here.
Although I can add now the BT devices they never connect with HLT...


There seems to be still an issue with Samsung and/or Android 13 using external BT devices.
I was some testing before heading to the track this weekend. Experiencing the same issues. Can add ODBLink LX and Garmin GLO 2 to the BT devices to the Sensors List but they never connect with HLT. They both work fine in the RaceChrono demo version.
