I use a Bluetooth Max2Play for Squeezbox, FHEM for home automation (ping Bluettoth on phone for presence) and Jivelite for connection to my 2.5 inch.
This all works perfectly but if there is a power failure or the raspberry Rebbot I lose bluetooth controller despite the check box activated at boot.
And if I run it bluetoothctl not find any controller so nothing works.
What order do I run to finally find my bluetooth controller for the moment the only thing that works and completely reinstall Max2Play
Thank you and congratulations for your work
