Bluetooth not working on Bullseye

[Parmenide78]

Good Evening,

I try to connect my audio in bluetooth, (I'm on Bullseye with version 2, because GPIO doen't work on Bookworm), and I have this result.

pi@phoenibox:~ $ bluetoothctl pair xx:xx:xx:xx:xx:xx
Attempting to pair with xx:xx:xx:xx:xx:xx
[CHG] Device xx:xx:xx:xx:xx:xx Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed
pi@phoenibox:~ $ bluetoothctl connect xx:xx:xx:xx:xx:xx
Attempting to connect to xx:xx:xx:xx:xx:xx
Failed to connect: org.bluez.Error.Failed

Is there a solution ?

When I tried on Bookworm (with version 3), it worked.
Is there a configuration where bluetooth and GPIO work ?

Thank you for your help :-)
