Bluetooth Issue(s) with fresh Debian Install
I just installed a new Debian system with KDE for my desktop. I was able to see my devices in the Bluetooth manager. I was even able to begin pairing. But the devices refused to connect. Instead I would get a generic “Protocol not available” error.
The fix:
I needed to install the `pulseaudio-module-bluetooth` package. Then I needed to restart pulseaudio.
`sudo apt install pulseaudio-module-bluetooth; sudo killall pulseaudio`
After this I was able to connect to my devices. I’ve read in some cases a reboot was needed as well — your experience may be different.
I don’t know why this package was not installed by default. I don’t know if Debian doesn’t include it on purpose, if there was some logic that didn’t determine it was needed, or if I just have an odd setup that prevented some default behaviors. Either way, the fix was relatively simple. Finding the fix in the first place, well lets just say it took longer than I wanted it to.
Diagnosing the issue
The GUI tool isn’t very helpful. You get a “Protocol not available” message in red for a moment. But no other details.
You can see a little more via the `/var/log/syslog` file. There you may see something like this:
