Hot to connect serial bluetooth device HC-05?

palto42

I'm trying to connect a bluetooth device "HC-05" which emulates a serial port, but on Solus linux there is no /usr/bin/rfcomm tool included in the bluez package it seems. I can pair the device successfully, but can't connect to it (no serial port created).
On other linux platforms like Ubuntu the serial port is created by using rfcomm to bind the device to a port like /dev/rfcomm0, see for example Using the HC-06/HC-05 Bluetooth Adapter For Serial Communication With Linux.
Is there any other option to bind the serial bluetooth port or how can I get the CLI tool rfcomm for Solus?

Seems like rfcomm is part of the deprecated tools for bluez so one would have to build it with the --enable-deprecated option.

Tried an alterative via Python which I found on Stackexchange, but the Python3 socket library on Solus seems to be compiled without Bluetooth.

Python 3.9.9 (main, Nov 22 2021, 09:28:41)
[GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> s = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'

My workaround is to use the rfcomm binary from Ubuntu 20.04 package.
