I'm trying to connect linux and android via Wifi Direct, especially Odroid-C1 and Galaxy S7. By using wpa_supplicant and wpa_cli, I successed make wifi direct connection, So Android shows Wifi Direct Connected as you can see below.(in the red rectangle)
The question is HOW CAN I DO SOMETHING like file transfer, even send PINGs!
In the wifi direct between two linux systems, each IP address can easily set, so I could use FTP or SSH. But the android, it is hard to know it's IP address, and almost every wifi direct app does not working.
Does anyone have clue about this situation??
