hi,

Thanks for the appreciation.

Unfortunately you can’t really do that, as by that point you will have most likely been disconnected from the module.

cheers

Hi,
I tried to modified function handleWifiSave by connecting wifi inside with connect_status after that check connection before sending web page to the server. when connecting success it showed "Success" on the web page before the auto close window. but when connecting failed, it can't show "Failed" in the web page. maybe you can figure out that situation.

void WiFiManager::handleWifiSave() {
  DEBUG_WM(F("WiFi save"));

  //SAVE/connect here
  _ssid = server->arg("s").c_str();
  _pass = server->arg("p").c_str();

  int connect_status = connectWifi(_ssid, _pass);
  //parameters
  for (int i = 0; i < _paramsCount; i++) {
    if (_params[i] == NULL) {
      break;
    }
    //read parameter
    String value = server->arg(_params[i]->getID()).c_str();
    //store it in array
    value.toCharArray(_params[i]->_value, _params[i]->_length);
    DEBUG_WM(F("Parameter"));
    DEBUG_WM(_params[i]->getID());
    DEBUG_WM(value);
  }

  String page = FPSTR(HTTP_HEAD);
  page.replace("{v}", "Credentials Saved");
  page += FPSTR(HTTP_SCRIPT);
  page += FPSTR(HTTP_STYLE);
  page += _customHeadElement;
  page += FPSTR(HTTP_HEAD_END);
  // page += FPSTR(HTTP_SAVED);
  page += "<h1>";
  if(connect_status == WL_CONNECTED)
  {
      page += "Success";
  }
  else
  {
      page += "Failed";
  }
  page += "</h1>"
  page += FPSTR(HTTP_END);

  server->sendHeader("Content-Length", String(page.length()));
  server->send(200, "text/html", page);

  DEBUG_WM(F("Sent wifi save page"));

  connect = true; //signal ready to connect/reset
}

This is hard to handle but it can be done, the problem is you have to disconnect ap to negotiate sta, and if sta fails then sta+ap is not even possible. So you have to disconnect sta and restart the ap all while having the page refresh properly.

It is definetly on list
