WiFi.softAPmacAddress();

This function does not return MAC address of the client, but the MAC of the AP.

Here is a working example. The reporting is haphazard and requires a pause between requests.

Update : I found this code here : viewtopic.php?f=32&t=5669&start=4 it reports the connected clients IPs and MAC addresses. All together it looks like this :

Code: Select all

/* configuration  wifi */
const char *ssid = "COblaster";

ESP8266WebServer server(80);

void handleRoot() {
  server.send(200, "text/html", "<h1>You are connected</h1>");
  //String addy = server.client().remoteIP().toString();
  //Serial.println(addy);
}

void setup() {
  delay(1000);
  Serial.begin(115200);
  Serial.println();
  Serial.print("Configuring access point...");
  WiFi.softAP(ssid);
  IPAddress myIP = WiFi.softAPIP();
  Serial.print("AP IP address: ");
  Serial.println(myIP);
  server.on("/", handleRoot);
  server.begin();
  Serial.println("HTTP server started"); 
}
 
void loop() {
  server.handleClient();   
  delay(5000);
  client_status();
  delay(4000);
}

void client_status()  /// This works, ty sohialsadiq!


{

unsigned char number_client;
struct station_info *stat_info;

struct ip_addr *IPaddress;
IPAddress address;
int i=1;

number_client= wifi_softap_get_station_num(); // Count of stations which are connected to ESP8266 soft-AP
stat_info = wifi_softap_get_station_info();

Serial.print(" Total connected_client are = ");
Serial.println(number_client);

while (stat_info != NULL) {

IPaddress = &stat_info->ip;
address = IPaddress->addr;

Serial.print("client= ");

Serial.print(i);
Serial.print(" ip adress is = ");
Serial.print((address));
Serial.print(" with mac adress is = ");

Serial.print(stat_info->bssid[0],HEX);
Serial.print(stat_info->bssid[1],HEX);
Serial.print(stat_info->bssid[2],HEX);
Serial.print(stat_info->bssid[3],HEX);
Serial.print(stat_info->bssid[4],HEX);
Serial.print(stat_info->bssid[5],HEX);

stat_info = STAILQ_NEXT(stat_info, next);
i++;
Serial.println();

}
delay(500);
}



The above code gets mac address only if the ESP8266 is acting as Access Point but if it is working as web server connected to lan then it doesn't give mac address
