Get SSID and PASSWORD for current connect WIFI

[expertup]

I make WIFI mesh network. After connect to WIFI I want to get SSID and passord for connect to painlessMesh network.

After enter data in config page, the functions wifiManager.getConfiguredSTASSID() and wifiManager.getConfiguredSTAPassword() working and return entered data, but after restart module these function return nothing.

How to is possible get SSID and password from current connection?

void setup() {
  Serial.begin(115200);
  
  AsyncWiFiManager wifiManager(&server,&dns);

  wifiManager.autoConnect("AutoConnectAP");

  mesh.setDebugMsgTypes( ERROR | STARTUP | CONNECTION );  // set before init() so that you can see startup messages

  // Channel set to 6. Make sure to use the same channel for your mesh and for you other
  // network (STATION_SSID)
  mesh.init( MESH_PREFIX, MESH_PASSWORD, MESH_PORT, WIFI_AP_STA, 6, 1 );
  mesh.onReceive(&receivedCallback);

  Serial.println("My SSID is " + wifiManager.getConfiguredSTASSID());
  
  mesh.stationManual(wifiManager.getConfiguredSTASSID(), wifiManager.getConfiguredSTAPassword());
  //mesh.setHostname(HOSTNAME);

  mesh.setRoot(false);
  mesh.setContainsRoot(true);

  myAPIP = IPAddress(mesh.getAPIP());
  Serial.println("My AP IP is " + myAPIP.toString());

  //Async webserver
  server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
    request->send(200, "text/html", "<form>Text to Broadcast<br><input type='text' name='BROADCAST'><br><br><input type='submit' value='Submit'></form>");
    if (request->hasArg("BROADCAST")){
      String msg = request->arg("BROADCAST");
      mesh.sendBroadcast(msg);
    }
  });
  server.begin();

}

Put these lines in setup() after wifiManager.autoConnect:

Serial.print("SSID: ");
Serial.println(WiFi.SSID());
Serial.print("psk: ");
Serial.println(WiFi.psk());

I will try this resolve
