wifi_command() issues a command to the Wi-Fi driver.
Android extends the standard commands listed at /link http://hostap.epitest.fi/wpa_supplicant/devel/ctrl_iface_page.html to include support for sending commands to the driver:
| Command / Command summary | Form of Response | Processing |
| DRIVER START Turn on Wi-Fi Hardware | OK if successful | OK ? true : false |
| DRIVER STOP Turn off Wi-Fi hardware | OK if successful | OK ? true : false |
| DRIVER RSSI Return received signal strength indicator in -db for current AP | <ssid> Rssi xx | %*s %*s d", &rssi |
| DRIVER LINKSPEED Return link speed in MBPS | LinkSpeed xx | %*s d", &linkspd |
| DRIVER MACADDR Return mac address of the station | Macaddr = xx.xx.xx.xx.xx.xx | "%*s = %s", &macadr |
| DRIVER SCAN-ACTIVE Set scan type to active | "OK" if successful | "OK" ? true : false |
| DRIVER SCAN-PASSIVE Set scan type to passive | "OK" if successful | "OK" ? true : false |
See libs/android_runtime/android_net_wifi_Wifi.cpp for more information describing how these and other commands are invoked.
| command | is the string command |
| reply | is a buffer to receive a reply string |
| reply_len | on entry, this is the maximum length of the reply buffer. On exit, the number of bytes in the reply buffer. |

| int wifi_wait_for_event | ( | char * | buf, |
| size_t | len | ||
| ) |

| buf | is the buffer that receives the event |
| len | is the maximum length of the buffer |
