Hallo Foni,
Danke für den Hinweis, habe ich nicht finden können. Es ist das originale Beispiel aus der Arduino IDE, ich habe lediglich die Define für die Kamera geändert.
Ein neues WLAN habe ich nicht gefunden, habe ich natürlich gleich geprüft.
Was ich nicht so ganz verstehe ist, dass das Beispiel "Einfacher Webserver", also ohne Kamera problemlos läuft.
Das ist der originale code:
#include "esp_camera.h"
#include <WiFi.h>
//
// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
// Ensure ESP32 Wrover Module or other board with PSRAM is selected
// Partial images will be transmitted if image exceeds buffer size
//
// You must select partition scheme from the board menu that has at least 3MB APP space.
// Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
// seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well
