pin based WPS authentication

[Padmanabha, Seshadri K.]

I got this working with "wps_pin any" to generate a pin and used this pin in p2p_connect command. What is the significance of pin showed in 
P2P-PROV-DISC-SHOW-PIN 84:dd:20:76:4a:ab 83987175?   Where exactly is this pin used?
                                                                                     ~~~~~~~~

Regards,
Sesh

Hello all,

I have a P2P peer trying to connect to a group owner. Here is the sequence that fails All user entered commands are prepended with [intf : xxxx]

---P2P Peer trying to join group--
[intf : p2pdev0] p2p_find 8 dev_id=5c:31:3e:d4:82:4f freq=2462

--Group Owner--
P2P-DEVICE-FOUND 84:dd:20:76:4a:ab p2p_dev_addr=84:dd:20:76:4a:ab pri_dev_type=1-0050F204-1 name='PEER_P2P' config_methods=0x108 dev_capab=0x25 group_capab=0x0

--P2P Peer trying to join group--
[intf : p2pdev0] p2p_prov_disc 5c:31:3e:d4:82:4f display join                                                                              

--Group Owner--
P2P-PROV-DISC-SHOW-PIN 84:dd:20:76:4a:ab 83987175 p2p_dev_addr=84:dd:20:76:4a:ab pri_dev_type=1-0050F204-1 name='PEER_P2P' config_methods=0x108 dev_capab=0x25 group_capab=0x0 group=p2pgrp0 

--P2P Peer trying to join group--
P2P-PROV-DISC-ENTER-PIN 5c:31:3e:d4:82:4f [intf : p2pdev0] p2p_connect 5c:31:3e:d4:82:4f 83987175 keypad join

WPS authentication kicks off after this and group formation failure occurs. Is the above sequence right?
