So my XM3 unable to connect when I change OS at boot (Win10 vs Debian11).
Short version (all in superuser, su or sudo):
$ bluetoothctl$ devices (this will print macaddresses)$ remove xx:11:22....$service bluetooth restart
Description:Some bluetooth device don't like pairing associated by same MAC address. Remove and repair bluetooth.
I installed Debian 11 but sometimes got connection error. Now I provide a simple solution to fix it in case the following:
sap-server: Operation not permitted (1)
At first the SAP stands for SIM Access Profile.
With vim edit "/etc/systemd/system/bluetooth.target.wants/bluetooth.service"
At line ExecStart=/usr/lib/bluetooth/bluetoothd add the following:
--noplugin=sap
Like this:
ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap
Now restart:
$ sudo systemctl daemon-reload
$ sudo service bluetooth restart
$ sudo service bluetooth status
You're becoming a happy user who able to connect to your Sony headphone.
Just a minor update:
For fresh Linux installment you can grab deb or rpm broadcom drivers:
