Other Parts Discussed in Thread: WL1271

Hi All,

I tried to implement Wifi Direct feature in my imx6 board with wl1271 chipset running on Android 4.3 and took reference from this link.

But when I tried to enable wifi from UI, I am getting following errors

E/wpa_supplicant( 3413): Could not read interface p2p0 flags: No such device
E/wpa_supplicant( 3413): p2p0: Failed to initialize driver interface

Have anyone tried to implement Wifi Direct Feature in Android 4.3 ?

Hi Teddy,

Have you created the p2p0 interface via the below command?
iw phy `ls /sys/class/ieee80211/` interface add p2p0 type managed

I think you can try adding it to your init.rc file.

Hi Gigi,

I am using the wl12xx driver version ol_R5.SP7.01. Does this version supports p2p by default or I need to change any configuration?

Hi Teddy,

Yes, the R5.SP7 supports WiFi Direct. Please see: http://processors.wiki.ti.com/index.php/WL127x_WLAN_and_Bluetooth_Demos for the demo guide.

Hi Gigi,
Does loading the wl12xx_module creates p2p0 interface?

Hi Teddy,

No, it doesn't. You have to create it yourself.

Hi Joseph,
While trying to test p2p0 interface using p2p commands under wpa_cli , I got the following error.

Did I miss something in my p2p configuration?

Hi Teddy,

I am not familiar with this issue... Possibly some issue with the interface...
