Hi,
Details of our platform is as follows
1. Hardware Platform: LPC313X
2. Kernel Version: 2.6.28.2
3. Compat Wireless package version: compat-wireless-3.5-rc5-1
Taken from http://linuxwireless.org/en/users/Download/stable/
4. WL1271 Firmware Revisions
a) Single Role : X.3.7.0.105 (Rev 6.3.7.0.105)
b) Multi-Role: X.5.5.0.21 (Rev 6.5.3.0.21)
5. WPA Supplicant Version: wpa_supplicant_1.1
6. IW Tool Version: 3.2
We are enabling multi-role operation(Station and AP(P2P GO) mode) using the following commands
1. Load the Compat wireless drivers (compat.ko,cfg80211.ko,mac80211.ko,compat_firmware_class.ko,rfkill_backport.ko, wlcore.ko,wl12xx.ko and wlcore_sdio.ko)
2. Set wlan0 as station
#ifconfig wlan0 hw ether 08:00:28:34:56:22
#ifconfig wlan0 10.2.30.34 netmask 255.255.255.0 up
3. Disable power save mode on wlan0
#iw wlan0 set power_save off
4. wlan1 as GO (Group Owner)
Create a new interface called wlan1 which would be configured as a GO(Group Owner)
#iw phy0 interface add wlan1 type managed
Configure Ethernet and IP address of the wlan1 interface
#ifconfig wlan1 hw ether 08:00:28:44:56:83
5. Start the interfaces
Start wlan0 as Station mode (run the WPA supplicant)
#./wpa_supplicant -d -Dnl80211 -c/wlan/wpa_supplicant_station.conf -iwlan0 -B
The wpa_supplicant_station.conf file contents is as follows
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="Cisco_WPA2-TKIP/AES"
psk="abcdefghijklmn*1234567890"
proto=RSN
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
auth_alg=OPEN
}
Get the ip addres for Station from AP
# udhcpc -i wlan0 -b
Start wlan1 in GO mode using the previously created p2p.conf(attached the file) file
#./wpa_supplicant -Dnl80211 -iwlan1 -c /wlan/p2p.conf &
The contents of p2p.conf is as follows
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
device_name=TI_WLAN_P2P
device_type=1-0050F204-1
config_methods=label push_button
# optional, can be useful for monitoring, forces
# wpa_supplicant to use only channel 1 rather than
# 1, 6 and 11:
#p2p_listen_reg_class=81
#p2p_listen_channel=1
p2p_oper_reg_class=81
p2p_oper_channel=1
network={
mode=3
disabled=2
ssid="DIRECT-BN"
key_mgmt=WPA-PSK
proto=RSN
pairwise=CCMP
group=CCMP TKIP
psk="12345678"
}
#./wpa_cli -i wlan1 p2p_group_add persistent=0 freq=2412
With the above steps the Role 1 and Role 2 will be started successfully
1. Start the UDHCPD server
#echo 1 > /proc/sys/net/ipv4/ip_forward
#ifconfig wlan1 10.4.30.39
#udhcpd /wlan/udhcpd.conf
The issue is, after starting P2P GO, may be after 2 to 3mins, the ping operation from any other PC/Laptop which is connected to the same AP as Station(wlan0) fails.
However, if I start the ping from my device to the PC/Laptop, ping operation succeeds and also ping from other side works(which failed before).
We suspect some issue while creating the multi-role interface(wlan1 for P2P GO) is causing the problem.
Any suggestions are welcome
Thanks & Regards,
Girish

BTW, this page seems to describe how to do what you're trying to do.

Did you see it? Maybe you can find some hints on what is going wrong.

Do you mean that before 2 to 3 mins elapse the ping works fine and then
stops working?

Seems to be because the device is sleeping or failing to wake up from
power saving.

Can you send some wl12xx logs so we can see what is going on?
