If you wish to install the drivers mentioned by @Dwaff, I think the easiest way is to do the following:
- Open a terminal and use a text editor like
nanoto open/etc/apt/sources.listusing the command
sudo nano /etc/apt/sources.list - Add the line
deb http://http.us.debian.org/debian stable main contrib non-free - Save the file. If using
nano, save the file with CTRL+O, then exit with CTRL+X - Run
sudo apt update - Then you can run
sudo apt install firmware-atheros
I think that should then allow Bluetooth to work (possibly after a restart). I haven’t tested it though.
