 ### Issue related to Pi Zero 2 W 2023-09-01
 There seems to be a problem with Bluetooth on the Raspberry Pi Zero 2 W and Raspbian GNU/Linux 11 (bullseye) where BTLE Scanning doesn't start. It's reported to work on the same hardware if running Raspbian GNU/Linux 10 (buster) https://github.com/wcbonner/GoveeBTTempLogger/issues/50 Any suggestions for a solution are appreciated.
