Hi !
I've been trying to setup a connection between two devices using WiFi
P2P.
I'm using two Netgear N150 Wifi dongles (chipset Realtek 8192CU).
Using the latest driver from Realtek (v.3.4.4) and the latest version of
wpa_supplicant from git repository the GO negociation fails while trying
to connect.
I'm working on XUbuntu (32 bit) 11.04 with kernel 2.6.38 on both
machines.
.config file to build wpa_supplicant :
--------------------------------------------------------------------
CONFIG_DRIVER_NL80211=y
CONFIG_CTRL_IFACE=y
CONFIG_WPS=y
CONFIG_WPS2=y
CONFIG_P2P=y
CONFIG_AP=y
wpa_supplicant.conf used to launch wpa_supplicant (sudo ./wpa_supplicant
-Dnl80211 -c./wpa_supplicant.conf -iwlan2 -dd) :
--------------------------------------------------------------------
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
device_name=8192CU_PC
device_type=1-0050F204-1
Steps followed :
--------------------------------------------------------------------
Device 1 >> p2p_find 5
Device 2 >> p2p_find 5
Device 1 >> p2p_connect 10:0d:7f:b9:ae:77 pbc go_intent=15
Device 2 >> p2p_connect 10:0d:7f:b4:1d:7d pbc
wpa_cli logs on device 1:

Do you have an idea about where this come from ?
Thank you,
