This article describes how to set up a bluetooth mouse with Arch Linux. I used a Logitech v270 with a Trendnet TBW-101UB USB Bluetooth dongle, but the general process should be the same for any model.

This article describes how to set up a Bluetooth mouse through the command line without relying upon a graphical application.

Installation

Install the bluez package which contains the current Linux bluetooth stack (Bluez5). You may also want to install bluez-utils which provides the bluetoothctl utility. See Bluetooth for more information.

Bluez5 instructions

Tip: Ensure that the bluetooth daemon is started before continuing.

The bluetoothctl utility provides a simple interface for configuring bluetooth devices. The text below is an example of how you can connect a bluetooth mouse using bluetoothctl:

# bluetoothctl
[bluetooth]# list
Controller <controller mac> BlueZ 5.5 [default]
[bluetooth]# select <controller mac>
[bluetooth]# power on
[bluetooth]# scan on
[bluetooth]# agent on
[bluetooth]# devices
Device <mouse mac> Name: Bluetooth Mouse
[bluetooth]# pair <mouse mac>
[bluetooth]# trust <mouse mac>
[bluetooth]# connect <mouse mac>

In order for the device to start on boot you may have to create a udev rule. Please see Bluetooth#Bluetoothctl for more information.

Tip: In case you were using USB Bluetooth dongle and moved it to another USB port, you may need to remove the mouse's MAC address in bluetoothctl with remove <mouse mac> command and repeat the entire procedure again.

Troubleshooting

Mouse lag

If you experience mouse lag you can try to increase the polling rate. See Mouse polling rate for more information.

Problems with the USB dongle

If you have trouble with your USB dongle, you may also want to try:

# modprobe -v rfcomm

At this point, you should get an hci0 device with:

# hcitool dev

Sometimes the device is not active right away. Try starting the interface with:

# hciconfig hci0 up

and searching for devices as shown above.

Mouse always disconnect

If the mouse stops working but works again after restarting bluetooth, you may need to disable USB autosuspend for the selected device.
