The Issue

After a fresh installation of Arch Linux (using archinstall), my bluetooth was not working. The GUI toggle would toggle on and directly off again.

The Culprit

Read: https://wiki.archlinux.org/title/bluetooth

Run: pacman -Qs bluetooth

The package bluez-utils was missing from my system.

The Solution

  1. Install the missing package: pacman -Syu bluez-utils

  2. Manual tryout: sudo systemctl start bluetooth.service

  3. Enable the service to auto-start it on startup: sudo systemctl enable bluetooth.service
