Hi, i'm blocked at the same point since monday :( I want to die, now ;)
I'm using one Nexus 5 and 2 Galaxy nexus s4 with KITKAT.

I followed the procedure explained by Jouni Malinen in the previous post.
This is the procedure that i'm following:

device1) p2p_connect "address_2" pbc persistent     ------> device 1 this is the GO
device2) p2p_connect "address_1" pbc persistent     ------> OK, i get AP-STA-CONNECTED

device1) wps_pbc
device3) p2p_connect "address_1" pbc persistent join     -------> on device 1 i receive <3>P2P-PROV-DISC-PBC-REQ

And after some seconds i receive on device 3:
<3>P2P: No pending Group Formation - ignore group formation failure notification
<3>P2P-GROUP-FORMATION-FAILURE 
<3>P2P-GROUP-REMOVED p2p-wlan0-0 client reason=FORMATION_FAILED

Please help me.

Thank u very much,
Stefano Cappa

WPS_PBC or WPS_PIN on the group interface to authorize a new P2P Device
to join the group as a client.

Nothing

P2P_CONNECT with " join" added to the end to request joining an existing
group rather than initiating a GO Negotiation to form a new group.

(and likely that dev3 starting first and dev1 reacting to the message
indicating that someone else wants to join)
