With the Toradex Embedded Linux Reference Multimedia the Bluetooth connection with a phone works.
I have also solved the issue with TorizonOs with a docker container with PulseAudio configured with load-module module-bluetooth-policy and load-module module-bluetooth-discover in /etc/pulse/default.pa. We also need to bind the volume /var/run/dbus between the board and the container.
If the container and PulseAudio are running, the profiles are added correctly.
