[AlmaLinux Users] Using bluetooth serial (RFCOMM) on AlmaLinux 9

I am running the latest AlmaLinux 9 on a Raspberry Pi 3/4 computer. I want to communication with a Bluetooth device that uses the serial communication (SPP) profile.

Using bluetoothctl I see the device, and I pair with it.

However, I can not establish the serial link, i.e. I don’t have a /dev/rfcomm0 device to communicate.

In other Linux distributions there exists the rfcomm command to connect to a Bluetooth serial device, but in AlmaLinux 9 this is not available.

How can I establish a serial link over Bluetooth, then? The rfcomm kernel is present in AlmaLinux 9.

Thanks, mb
