How can I control my Bluetooth devices on linux?
The easiest way of controlling Bluetooth devices on a Linux host is by using the Bluez package which can be found at the below link: https://github.com/bluez/bluez
It is natively supported from kernel 4.4 and by installing the bluez-utils package you can use the command line tool, bluetoothctl for configuring and pairing your Bluetooth.
Make sure that the bluetooth.service is running on your host device which can be checked with the command,
$ sudo systemctl status bluetooth.service
and started with,
$ sudo systemctl start bluetooth.service
In addition, make sure that the drivers are properly installed and loaded. Sometimes, WiFi drivers only include drivers for WLAN over PCI and an additional set of drivers are needed for Bluetooth to function in parallell over USB.
The package can support earlier kernel verision by backporting the package which supports the below basic features:
3.13 basic bluetooth classic and LE functionality
3.10 basic bluetooth classic
For basic troubleshooting, the Arch Linux wiki has a thorough guide at the following link:
