After a suspend and resume, bluetooth stops working. Unable to restart service and a reboot is required.
I noticed from another post....
There is a known bug in Mint 21 that causes Bluetooth to turn off after the computer goes to sleep. The workaround is to turn off the "Suspend when inactive for" setting in the Bluetooth settings.
....but not sure where to find this either in /etc/bluetooth or blueman settings

Only other thing is the blueman applet has gone from the tray - blueman-adapters doesn't list any adapters. Could that have anything to do with it although Bluetooth is running ok apparently. Sorry complete newb
