From: Jefferson Delfes <jefferson.delfes@xxxxxxxxxxxxx>
An observer for Service Data must be registered using
RegisterServiceObserver() D-Bus method so it can receive any advertising
which matches with the filter used. Use UnregisterServiceObserver()
D-Bus method for unregistering an observer and stop sending broadcasts
to the agent.
