Recently I bought a bluetooth RS232 serial convertor. I wasn’t sure whether it would work with my Linux laptop. But it turned out to be quite simple to setup.

Pre-requisites

The following packages are required:

• bluez
• bluez-utils
• byobu (optional)

Bluez provides the bluetooth protocol stack (most likely shipped with the OS), bluez-utils provides the bluetoothctl utility and byobu is a wrapper around screen terminal emulator. You can also use ‘screen’ directly. Install these using your distributions recommended procedure.

Steps

1. Start daemon:

1

    Swanky:~$ systemctl start bluetooth

2. Discover using bluetoothctl:

    Swanky:~$ bluetoothctl
    [NEW] Controller <controller-mac-address> xkgt-Swanky [default]
    [bluetooth]# power on
    [bluetooth]# scan on

3. Once you can see your device, turn off the scan and pair

1
2

    [bluetooth]# scan off
    [bluetooth]# pair <device-mac-address>

4. Exit blutoothctl and create serial device (Note that root privileges are required):

1
2

    [bluetooth]# exit
    Swanky:~$ sudo rfcomm bind 0 <device-mac-address>

5. You should now have /dev/rfcomm0. Connect to it using byobu-screen utility:

1

    Swanky:~$ byobu-screen /dev/rfcomm0

Enjoy your wireless console connection!
