A fresh install of Leap 15.6 RC1 is capable of pairing with a phone.
But it fails to send (and perhaps also receive) files:

blueman-sendto[26154]: gi.repository.GLib.Error: g-io-error-quark: Fehler beim
Aufruf von StartServiceByName für org.bluez.obex: Unit
dbus-org.bluez.obex.service not found. (36)

This is when selecting "Send file" in the "blueman-manger" application.

I think this is supposed to work out of the box.
Attached is the list of installed packages during the "default XFCE"
installation.
