I have been working on the Linux side of an effort to connect to a Windows 10 machine using the sample apps from Microsoft to connect via Wi-Fi direct. We are experiencing a disconnect shortly after connect but the reason for the deauthentication is unknown (1).
I have put the config file contents below and a section of the log output where the issue occurs.
The supplicant is started using:
wpa_supplicant -iwlan0 -Dnl80211 -c/etc/wcm/wpa_supplicant.conf -t
We control the supplicant via an executable we have made that interacts with the supplicant as wpa_cli does. A p2p-find is performed and when the invitation/pbc request from the Windows 10 machine is received, we respond with:
p2p-connect 18:1d:ea:b0:96:a0 pbc persistent=0
where the MAC address is peer address from the Windows 10 request.
If you look in the log output at the bottom of this pst you can see the station (Windows 10 machine) connects and then disconnects shortly afterward.

wpa_supplicant verbose logging where we see the Windows 10 machine connected and then shortly thereafter disconnected related to some authentication issue:
