- the Deui frontend.

For issues related to bluetooth, refer to abandonware/noble. Most of what can happen is already described in their README.
The error means "failed to establish connection" and happens after a successful scan. One thing that can help
systemctl status dbus
systemctl enable bluetooth.service
