there is no feature to measure the RSSI between peers in Wifi-direct, so how to get RSSI between them.

actually i go under API for WIFI to see how they measure WIFI RSSI So i see that they send Command as parameter to native method, but i can't catch this command!!!

in this method wifi_send_command in wifi.c from this link.

as i know Android is under linux, the iwconfig is linux command to get the wireless information interface, if i used it can i get the Wifi direct information ? or it is just return the access points network information?

anyone have any idea about this ?

You can get this information inside wpa_cli. Open wpa_cli in wifi-direct interface and do a scan and scan_results as below.

adb shell wpa_cli -i<wifi-direct interface name> -p<socket path> scan
adb shell wpa_cli -i<wifi-direct interface name> -p<socket path> scan_results

You will get small info about connected peer(device address, channel,rssi etc). Hope this works!

wpa_cli is a command line interface for the wpa_supplicant which you are running in android. It will be in /system/bin by default(i hope so). This is just like scanning peers(not wifi-direct searching) and getting scan results. RSSI will be there in the scan results info. –  Rilwan Mar 5 '13 at 9:34
