Hi,

I am using Linux Kernel v4.9.9 and wpa_supplicant 2.6. When
running
'wpa_cli wps_pin any', the following messages are printed:

"""

.. and nothing happens. The data sheet for the BCM43362 states
that
the
module supports WPS.

Hi Jörg,

We have never tested WPS with brcmfmac. Most of it is in firmware
so
it
might work. We had some fixes related to setting management IE,
but
it
should be in 4.9. I did not check it (yet).

As it turns out, WPS does not work if a network configuration in
wpa_supplicant has the flag `mode=2` (access point mode) set:

"""
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
	ssid="AP"
	key_mgmt=NONE
	mode=2
	id_str="ap"
}
"""

Setting mode=2 for a network and having ap_scan=1 (default) means
if no
APs matching to the currently enabled networks are found, a new
network
 (IBSS or AP mode operation) may be initialized (if configured).

So, WPS does not work if the interface is operating in AP mode. I
wonder, if this is a desired behavior? At least, wpa_supplicant
does
not complain, but prints "WPS-PBC-ACTIVE", but no messages are
following, until "WPS-TIMEOUT".

So what do you expect exactly? Are you trying to connect with some
other
device to this AP interface?

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.
