Can anyone tell me, is there any option to customize wifi direct channels? I need to customize it not only between ch1, ch6 and ch11, but also in another channels selected by me. How can I do that?
In order to change the channel of the Wifi Direct of your device you need to do the following:
1- Root your phone
2- Download any File manager App: Such as ES File Explorer
3- On ES File Explorer, go to Tools, then turn ON the Root Explorer and click on it then mount RW
4- Using ES File Explorer, go to Device -> Data -> Misc -> Wifi -> p2p_supplicant.conf and change the p2p_oper_channel to whatever channel you want.
5- Turn OFF the Wifi of your phone then turn it ON in order for the change to take place.
You should note that in order for the Wifi direct channel to be the one you did set, the phone needs not to be connected to any Access point when the wifi direct connection starts. Also, usually when phone A connects to phone B via wifi direct, the connection is operating on phone B's channel.
Hope this helps
