Hi,
I'm using OBDLink CX adapter for getting live data from my BMW i3 into ABRP running on my Android 13 phone. On first connect after car had been parked for a while this is working flawlessly. But if I leave my car parked for only a couple of minutes and return to it in order to continue my ride, most of the time ABRP fails to reconnect to the OBD dongle. In Android bluetooth settings the dongle is then marked as not connected and trying to trigger a bluetooth connection from the phone has no effect.
Which makes this issue more of a concern is that in this state, ABRP still indicates to be correctly connected to the dongle. This means it shows connected in ABRP on phone car connection page as well as showing the green bluetooth logo next to the current SoC display in Android Auto screen, yet the values reported (e.g. SoC) is obviously no longer correct and sometimes even erratic.

I'm not perfectly sure if ABRP is to blame for the reconnect issues, but showing a proper connection in ABRP while connection is actually broken does not help in trusting SoC display and charging stop planning of ABRP.

Would be great I you could have a look into this issue.

Thank you!
BR, Tobi
