Is it possible to get mac addresses when scanning networks? ESP32

Question

I need to get the RSSI of the networks and they MAC addresss to a IPS (indoor position system) program. I was able to get ssid, signal strength and security using the sample code, but not mac addresses. I tryed to use this, but itsn't working:

void loop() {
  int n = WiFi.scanNetworks();

  if(n == 0){
    Serial.println("no networks found");
  }
  else{
      for (int i = 0; i < n; ++i) {
        Serial.print(i + 1);
        Serial.print(": ");
        Serial.print(WiFi.SSID(i));
        Serial.print(" (");
        Serial.print(WiFi.RSSI(i));
        Serial.print(")");
        Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?" ":"*");
        Serial.println(WiFi.macAddress(i));
        delay(10);
      }
  }
  delay(10000);
}

@Tarmo's answer is correct, but the Arduino core does provide a simpler interface to getting the AP's access point without having to directly call ESP-IDF functions.

Use the BSSID method to get the MAC address of the base station's wifi radio.

You can call either the BSSID() method to get a pointer to the six byte MAC address or BSSIDstr() to get the MAC address as a string.

So for instance:

        Serial.print(WiFi.BSSIDstr(i));

will print the MAC address as a string.

When you're stuck on this kind of things referring to the library's source code can help you find out more than documentation and tutorials may.
