Hallo Sara,
ich habe das gleiche Problem mit diesem Projekt…
Ich habe den Code erfolgreich hochgeladen.
Ich erhalte diese Meldung:

Kamera bereit! Verwenden Sie „10.100.102.205“ zum Verbinden
Verbindung zum WLAN wird hergestellt…
SPIFFS erfolgreich gemountet
IP-Adresse: 10.100.102.205

aber wenn ich versuche, ein Foto aufzunehmen, erhalte ich diese Meldung: „

Hi.
Downgrade your ESP32 board to version 3.0.7.

I get the infamous

assert failed: tcp_alloc /IDF/components/lwip/lwip/src/core/tcp.c:1851 (Required to lock TCPIP core functionality!)

error, with the latest packages installed.

My board is branded GERUI, but it’s like the AI thinker board. The code compiles fine.

Thanks, Lh

Thank You for nice example.
The sketch code slightly outdated.
Please, remove #include and replace “request->send_P” with “request->send”.
It works!
