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.
