[android-developers] Wi-Fi Direct WPS overlap problem in Android

Hey everyone,

I've been spending a lot of time with Wi-Fi Direct the past months, one of the problems I've run into that is also present inside the Android Wi-Fi Direct settings menu is that if you try to connect two(or more) peers to one and the same peer at the same time or very shortly after each other, Android will "drop" one or both peers giving an error message in the logs that a WPS overlap was detected.

Sadly there seems to be nothing in the Wi-Fi Direct documentation mentioning this, nor anything in the Wi-Fi Direct API that will help you identify that this is happening and dealing with it afterwards.

Has anyone else run into the issue, or can an Android Developer shed some light onto dealing with this problem, it's pretty blocking since it would prevent users from having a normal user experience with my application, I can't really go asking them to connect sequentially one by one now can I, if someone disturbs that process the whole system can sometimes lock up, not being able to withdraw invitations for example and thus never being able to connect at all until Wi-Fi Direct is rebooted completely.

In short: Peer 1 and 2 are trying to connect to peer 3 at the same time. The result is both connection requests are getting dropped due to WPS overlap.

The logs I'm getting are:
