p2p_invite issue!

[Shah, Nirav J2]

Hey Jouni, 

Thanks a lot for offering to help with this. 
I have sent the logs to you some time back. Couldn't send it to the mailing list because of the size constraint. Did you get the chance to look at them at all? 

Thanks,
Nirav.

Does that really work for you with mac80211_hwsim? I'm getting scan failures and p2p_find FAIL when trying this with the GO running. Or did you use separate group interface?

Do you leave p2p_find running when running this? Please note that p2p_find is pretty much trying to use all possible time for device discovery and that makes it quite difficult to do any concurrent operations.

Other than missing p2p_stop_find on the GO, I did not notice incorrect commands.

Please send debug log from both the GO and the P2P client. When I try to do this with mac80211_hwsim (though, with single interface and p2p_find on the GO prior to running p2p_group_add), invitation and p2p_connect join seem to work fine.
