How to get Access Point MAC adress

Postby GEOLOCWIFI » Thu Nov 17, 2016 6:23 pm

Hi Everyone !

My ESP is in station mode, I can get the RSSI of few APs in my school but I can't get the MAC adress of this APs.
Is there anyone who knows how to get theses informations ?

Thank you!

Are you using the SDK? If yes, here is how you do this:

You can access the MAC address of any AP the moment the ESP8266 connects to it by registering a WiFi event callback:
void wifi_set_event_handler_cb(wifi_event_handler_cb_t cb);

The function could be of the form:

Code: Select all

void wifi_handle_event_cb(System_Event_t *evt) {
os_printf("event %x\n", evt->event);
switch (evt->event)
os_printf("connect to ssid %s, channel %d\n", evt->event_info.connected.ssid, evt->;
os_printf("AP MAC address is  %s\n", evt->event_info.connected.bssid);

case ....

The line
os_printf("AP MAC address is %s\n", evt->event_info.connected.bssid);
will get you the MAC of the currently connected AP in station mode.
