# Bluetooth #
if the following fails to connect/pair successfully, then issue the following command:
`sudo rfkill unblock bluetooth`
So to start we issue the following commands to make sure that bluetooth is running and enabled.
`sudo systemctl restart bluetooth`
`sudo systemctl enable bluetooth ` (this is only if you wish bluetooth to start at boot-up)
we can then check that this is so with:
`systemctl status -l bluetooth`
You can then enter the bluetooth shell with:
`bluetoothctl`
Turn the power on and find out the device MAC address:
`power on`
`devices`
if not paired you can enter `pair MAC_ADDRESS`. if already pair you can enter `trust MAC_ADDRESS`
then enter `connect MAC_ADDRESS`
you can now exit and use pavucontrol or the scripts pa-global or pa-solo to redirect sound to the headset.

To prevent audio autoskipping with the A2DP profile try the following:
`echo "options iwlwifi bt_coex_active=0" | sudo tee -a /etc/modprobe.d/iwlwifi.conf`
This disables the bluetooth coexistance parameter of the iwlwifi module (sometimes wifi intereferes with the bluetooth)
In this setups case the file may actually be 50-iwl3945.conf so modify the above as follows.
`echo "options iwl3945 bt_coex_active=0" | sudo tee -a /etc/modprobe.d/50-iwl3945.conf`
