Issue with receiving psk during WPS over D-BUS

[Radoslaw Martyniszyn]

Hello,

I have a questions about obtaining psk and connection parameters using
wpa_supplicant d-bus API with WPS. Could you please answer it? Thanks
in advance.

I use wpa_supplicant 2.6. I am calling method Start of
fi.w1.wpa_supplicant1.Interface.WPS with the following parameters:
"Role" -> "enrolee"
"Type"-> "pbc"
"Bssid" -> my AP bssid

After pressing WPS button on my AP I am connected, but unfortunately I
am not receiving psk. I dont know which properties are responsible for
psk and other connection parameters? Could you please advice me how to
obtain AP's psk? Without obtaining psk I am unable to connect to AP
using AddNetwork next time.

On the contrary when I use "wps_cli wps_pbc" then after successfully
connecting to AP I have psk in wpa_cupplicant configuration file in
the "network" structure.

Below is log from my D-BUS call:
