Set up the bluetooth - error : dbus-service-type: unbound variable

Set up the bluetooth - error : dbus-service-type: unbound variable

Hello Guix!

Wanting to use bluetooth devices, especially audio speakers, I have tried to
inser in my /etc/config.scm some relevant gnu packages, modules, services...
But I can't make it work
My config:
--8<---------------cut here---------------start------------->8---

(use-service-modules desktop networking ssh xorg virtualization audio dbus sound)

Hi Guix!
I have now bluetooth enabled, many thanks to Mario Forzanini (he forgot to add the mailing list in Cc :)

<snip>
 (use-modules (gnu services base)
                (gnu services desktop))

 (operating-system
     ; ...
     (services
         (cons
          (service bluetooth-service-type
                   (bluetooth-configuration
                    (auto-enable? #t)))
          %desktop-services)))
<snap>

Good afternoon guix!
