Not yet, wm currently shutsdown the ap to attempt the connect (for stability), so maintaining a webservice is a problem.

Thanks for info.

I solved it like this:

void loop() {
if (state == 103) { // state where I turn WM ON via button press
    wifi_config_t conf;
    esp_wifi_get_config(WIFI_IF_STA, &conf);
    apName = String(reinterpret_cast<const char*>(conf.sta.ssid)); // reading SSID from flash which should be empty
    if (apName != NULL) { // if SSID is not empty 
      Serial.println("Registered new SSID: " + apName);
      startTime = millis(); 
      if (WiFi.localIP()[0] > 0) { // if IP address is not 0
        setupWiFiScreenDone(); // call for scrren which shows full IP address
      } else {
        //if we did not get IP address, we have to clear SSID
        WiFi.disconnect(true);
        Serial.println("No IP address, restart WiFi setup.");
        setupWiFiScreenFail(); //information screen, which after timout calls another screen with state 103
      }
    }
  }
}

This works, but I have to enter SSID manualy as I have this issue.
