How to Pair Apple AirPods/AirPods-Pro on Debian Bookworm

Setting Up

2. 2. Installing Dependencies

   Then to Install Required Software
   Simply play:

   sudo apt install bluez* ofono ofono-phonesim

   Authenticate with the User Admin Pass.
   If Got “User is Not in Sudoers file” then see: How to Enable sudo.

3. 3. Loading Bluetooth Kernel Module

   Now try to Load Bluetooth USB Kernel Module
   With:

   sudo  modprobe btusb

   And then Restart Bluetooth Service:

   sudo systemctl restart bluetooth

4. 4. Configuring

   Next to Configure Apple AirPods Bluetooth backend
   First, you can try with this set up:

   sudo nano /etc/bluetooth/main.conf

   Set the “ControllerMode” in “bredr” or possibly “dual”:

   

   Ctrl+w to Search.
   And Ctrl+x to Save & Exit from nano Editor!
   Now Restart the Bluetooth Service:

   sudo /etc/init.d/bluetooth restart

   Next you can test Pairing the Device and if is Not working then proceed with the further instructions below.
   So another possible solution is editing the oFono Configuration:

   sudo nano /etc/pulse/default.pa

   Search for “load-module module-bluetooth-discover” and Change the line as:

   load-module module-bluetooth-discover headset=ofono

   Save it ad Exit as on the former Instruction.

   

   Then Add the User “pulse” to the Group “bluetooth” as:

   sudo usermod -aG bluetooth pulse

   Follow Granting the neede Permissions editing:

   /etc/dbus-1/system.d/ofono.conf

   Search for “</busconfig>” and right before it Insert:

   <policy user="pulse">
   <allow send_destination="org.ofono"/>
   </policy>
   

   Save & Exit.
   Again configure also Phonesim editing the File:

   /etc/ofono/phonesim.conf

   And appending:

   [phonesim]
   Driver=phonesim
   Address=127.0.0.1
   Port=12345
   

   Save it and Exit again.
   Now Restart oFono Service with:

   sudo systemctl restart ofono.service

   And again Phonesim:

   ofono-phonesim -p 12345 /usr/share/phonesim/default.xml

   Eventually to Test the Phonesim set up use this workflow:

   cd /tmp

   git clone git://git.kernel.org/pub/scm/network/ofono/ofono.git

   cd ofono/test

   ./list-modems
