Moin,

dir fehlt wie es scheint ein Paket für Pulse

sudo apt install pulseaudio-module-bluetooth

Gruß Stephan

Hallo, dadurch hat sich leider nichts geändert.

Gruss Schwabenpfeil

Das von Stephan genannte Bluetooth-Paket ist installiert.

Jetzt folgenden Befehl eingeben:

killall pulseaudio

Danach Bluetooth deaktivieren und wieder aktivieren. Nun sollte es möglich sein, die Verbindung herzustellen.

Leider keine Veränderung.

Gruß Schwabenpfeil

Habe gerade versucht mein Smartphone zu koppeln und bekomme diese Meldung: Paired successfully, but this device has no services which can be used with Raspberry Pi.

Ich benutze keinen Raspberry Pi, ich habe ein Lenovo ThinkPad.
