QDbus from Python: read DBus property

Mark81

Hello, I wrote a couple of Python lines that work:

def get_prop(bus, service, object_path, interface, name):
    obj = bus.get_object(service, object_path)
    iface = dbus.Interface(obj, 'org.freedesktop.DBus.Properties')
    property = iface.Get(interface, name)
    print(property)

bus = dbus.SystemBus()
get_prop(bus, 'org.bluez', '/org/bluez/hci0/dev_xx_xx_xx_xx_xx_xx/player0', "org.bluez.MediaPlayer1", "Status")

This is a common way to read a DBus property.
I'm in trouble to translate this to Qt5:

QDBusInterface *iface = new QDBusInterface("org.bluez", "/org/bluez/hci0/dev_xx_xx_xx_xx_xx_xx/player0", "org.freedesktop.DBus.Properties", QDBusConnection::systemBus(), this);
qDebug() <<  iface->call("Get",  "org.bluez.MediaPlayer1", "Status").arguments();

but it returns:

QVariant(QDBusVariant, )

Where is my mistake?
Is there a more convenient way to read DBus properties?
