I was wondering if anyone has observed something similar:
I have uploaded firmware, and am running the app on 2 phones. Before the modules go to sleep, I can successfully send messages back and forth, see location and change channels.
But, on the older of the phones (running android 5.1.1), after the TTGO goes to sleep, the bluetooth on the phone switches off, and cannot be switched back on!
The meshtastic app asks for permission to restart bluetooth, but it never restarts.
Any assistance appreciated.
