'bluetoothd -P input' not working on Ubuntu 22.04

[guliteb]

I am using Ubuntu 22.04. BlueZ is native installed. When I run 'sudo bluetoothd -P input', it shows ''D-Bus setup failed: Name already in use'. And then running 'sudo python3 main.py' resulted in 'Address already in use'.

How should I resolve this failure?

Thanks.

Can you double check whether the Ubuntu has also started another bluetoothd?
Like normally many distros that I have seen will have a systemctl status bluetooth service running in the background by default. If you found one, you have to stop it or change its startup options.

Thanks. It works after I run systemctl stop bluetooth and manually start sudo bluetoothd -P input.
