Bluetooth in Arch Linux

I installed Arch Linux on my new laptop a couple of months ago, and strangely enough, never used Bluetooth on it yet. Bluetooth in Arch Linux can be fun and interesting at times. I wanted to use my favorite Sony headphones on my laptop (It only has Arch Linux on it, no Windows!), so I thought I’d document the process.

Step 1: Install Bluez and Blueman

sudo pacman -S bluez sudo pacman -S bluez-utils sudo pacman -S blueman 

These should install without a problem. You’ll see a neat icon here:

Next, make sure the btusb Kernel module is loaded:

Here’s a trick to help it find adapters, even if you plug one in:

sudo vim /etc/bluetooth/main.conf

2. Enable the Service

Next, we want to try starting up the service:

sudo systemctl start bluetooth.service 

If you want it to start up automatically, enable it:

sudo systemctl enable bluetooth.service 

Now we should be up and running. You can turn on all adapters with Blueman:

Now you should be ready to connect and pair.

3. Pairing

Blueman makes pairing pretty easy:

And you’re done connecting!

If you’re connecting headphones like I am, there are a few more steps.

Connecting Audio

First off, I’ll install pulseaudio and the Bluetooth extension.

sudo pacman -S pulseaudio sudo pacman -S pulseaudio-bluetooth 
sudo systemctl pulseaudio start 

If you want it to start up automatically:

sudo systemctl start pulseaudio 

One utility I like to use to control audio (point it towards my speakers or the headphones) is Pavucontrol.

sudo pacman -S pavucontrol pavucontrol 

This is a great way to switch back and forth:

Note: If You Have a2dp

If your audio devices uses a2dp (Advanced Audio Distribution Profile), you may get the following error:

Bluetooth in Arch Linux

Connection Failed: Protocol not available

Here’s how to fix it. There’s a gdm fix, so it connects upon login (if you’re using GDM)

cd ~/src git clone https://aur.archlinux.org/pulseaudio-bluetooth-a2dp-gdm-fix.git makepkg -i 

You’ll also need to do this:

Here’s a hotfix that I found that worked. Check out this gist.

Use this content for your bt-autoenable-a2dp.sh file:

mkdir -p ~/.config/scripts/xorg vim ~/.config/scripts/xorg/bt-auto-enable-a2dp.sh sh ~/.config/scripts/xorg/bt-auto-enable-a2dp.sh 

Create a udev rules file and add this content

sudo vim /etc/udev/rules.d/20-bt-auto-enable-a2dp.rules 

Now you should be up and running and listening to audio! It worked for my WH-1000MX3 headphones.
