Sorry, I got confused. The device operating in AP mode shall be
connected to some other AP as a station. Of course, WPS cannot be used
to do so as long as the interface is operation in AP mode, as the
device should be the WPS enrollee and not the registrar. My bad! Thanks
for pointing that out.
So, to use WPS for connecting the device to another AP I have to bring
the interface into an non-AP mode first.
So, I can confirm that using WPS works when the interface is
unconfigured. However, if the in the interface is in AP mode and WPS is
started the error messages pop up.
