  válasz Janos250 #17917 üzenetére

  Már szerkeszteni nem tudtam

  Szeretnék egyet kérdezni, ha tud valaki segíteni ebben.
  Van ebben a könyvtárban webserveres példaprogram.

  Viszont én már az ESP32 ota feltöltéshez is azt használok, ebbe belezavar ha most a kijelzőét is beletenném a programba?

  Ezek első blikkre mindkettőben ott vannak

  MDNS.begin(host);
WebServer server(80);
server.begin();
server.handleClient();
