Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1560

WiFimanager Branch/Release: 2.0.15-rc.1

Esp8266/Esp32: ESP32

Core Version: ARDUINO IDE 2.0.3 | ESP-IDF 4.4

Problem description

Hi,
i was trying to set a custom hostname for my project and using WiFi.hostname() or WiFi.setHostname didn't work. code compiled succesfully and library worked well; it created the AP and then switched to my wifi network properly. I also tried setting darkmode and the app looked the same way :c. I tried puting the lines with the configuration at different parts of the setup and had no result.

i read a problem from august related to this claiming that it was solved. maybe is a problem with arduino ide, should i only use vs code and arduino as a component? can i use the latest ESP-IDF version (5.0) if i work with arduino as a component (in vs code) or i am anyways limited by arduino?i really want to use this library, can i use it directly from IDF?

i'am really a newby with wifi protocols and i switched to arduino just by beeing uncapable of dealing with wifi directly on the idf without any library to help me.

Module: ESP32 DEV MODULE

  resetCounter++;
  ESP_LOGI(*TagSETUP,"Starting protocols...");
  initGPIO();
  initISR();
// configs start here...
  WiFi.setHostname("My ESP"); //define hostname
  wm.setClass("invert"); // dark theme
  wm.setMinimumSignalQuality(10);
// i tried moving this part above before and after all the functions of the library.
  WiFi.mode(WIFI_STA);
  wm.resetSettings();
  bool res;
  res = wm.autoConnect("1234-Setup","1234setup");
  if(!res){
    ESP_LOGI(*TagSETUP,"Failed to connect to AP.");
  }
  else {
    ESP_LOGI(*TagSETUP,"WiFi Connection established succesfully.");
  }

  ESP_LOGI(*TagSETUP,"Setup ended succesfully.");
}

void loop() {
//i am not looping anything yet...
}
#END

Debug Messages

no debbug messages, code is compiling and working(except those functions)
