Targus bluetooth dongle shows to be working, but will not connect

English Applications
1

My Targus BT adapter always worked in Leap, up to and including 15.4
I upgraded to Tumbleweed and although it shows to be working, it will not connect nor will it accept a connection. Using bluedevil5 5.26.2-1.1 over bluez 5.65-4.1 the devices see each other and present matching pins, but the setup fails. After failure, both devices appear in the device list of the opposing device. When I try to manually connect, I get:


 br-connection-profile-unavailable

dmesg output after hot plug is:

and kernel-firmware-bluetooth 20221031-1.1 is installed as well. The device works fine.

In case it’s only the file transfer via bluetooth that is not working on your system: have a look here.

Thank you. Very helpful. I see that users reported that obex was not installed as an associated app back in April. Hopefully they will make it a prerequisite for bluez soon. I installed it manually. I set up the “systemctl --user start obex” command as a startup script in Plasma. Problem is solved.

You can do (as a “plain” user)

> systemctl --user enable obex 
Created symlink /home/USER/.config/systemd/user/dbus-org.bluez.obex.service → /usr/lib/systemd/user/obex.service.
>

and the service should be started automatically on login (so no need for a startup script).
