Conectar a dispositivo bluetooth en ArchLinux

Bluetooth is a standard for the short-range wireless interconnection of cellular phones, computers, and other electronic devices. In Linux, the canonical implementation of the Bluetooth protocol stack is BlueZ.

Installation

1. Install the bluez package, providing the Bluetooth protocol stack.
2. Install the bluez-utils package, providing the bluetoothctl utility. Additionally install bluez-deprecated-tools to have the deprecated BlueZ tools as well.
3. The generic Bluetooth driver is the btusb kernel module. Check whether that module is loaded. If it is not, then load the module.
4. Start/enable bluetooth.service.

sudo pacman -S bluez bluez-utils
sudo systemctl start bluetooth
bluetoothctl
> power on
> agent on
> scan on
> devices
> pair MAC_ADDRESS
> connect MAC_ADDRESS

En caso de una mala conexión usar disconnect MAC_ADDRESS
