====== Connect XBox Controller over Bluetooth in Linux ======

Part of [[:computer_science:linux:linux|Linux]]

===== Overview: =====

  * Make sure you your bluetooth adapter is detecting bluetooth devices of any kind eg: your smartphone is visible and it's found
  * Use "jstest-gtk" to test that if the buttons / analogues are working as expected
      * If not, but the controller is connected, "xboxdrv" might be missing

===== How To: =====

  * Install "jstest-gtk" and make sure you have your "blueman" packages installed
  * Using "blueman-manager" search, connect and pair with your XBox Controller
      * To start pairing on the Controller, press and hold the button that is in between the L/R triggers until the light flashes rapidly
  * If you are connected, use "jstest-gtk" to see if the control is being detected when pressed. If not:
      * install "xboxdrv" and re-pair your controller
  * If you are on an older firmware (pre 5.12) you might need to disable ERTM (Enhanced Re-Transmission Mode)
      * Temporarily:
        * sudo -i
        * echo 1 > /sys/module/bluetooth/parameters/disable_ertm
        * exit
        * sudo systemctl restart bluetooth
      * Permanently
        * sudo nano /etc/modprobe.d/bluetooth.conf
          * options bluetooth disable_ertm=Y

===== Extra help: =====

If you require a bluetooth gui helper for connecting and making sure it's working, you can't go wrong with "bluetooth-wizard", part of "bluez-gnome".

This can help in identifying issues in case you can't detect anything, and you are not sure if the issue is on the XBox controller or in your Bluetooth adapter.
