Set Up Bluetooth in Linux

1. Start by installing bluez*. It adds a bunch of drivers and will most likely be the reason why your headset works now.

    sudo apt-get install bluez*
   

2. Install blueman, this will help connect to your headphones.

   sudo apt-get install blueman
   

3. Go into the file /etc/bluetooth/main.conf

   sudo vim /etc/bluetooth/main.conf
   

4. Change the following lines:

   ControllerMode = bredr
   

   or

   ControllerMode = dual
   

5. Save the file and exit, then run the command:

   sudo /etc/init.d/bluetooth restart
