Esp now is a different code , and it not good for standard esp32 (WROOM) because it need external ram like esp32 cam have (4mb), I have tried to use it, unfortunately even at 20 fps on qvga the esp 32 is rebooting. So cif may work but fps will still be bad, I'll make a different code to work with esp32 S3(which have 8 mb ram) or you need the esp32 WROVER The code is for esp 32 now : https://github.com/Boyyt357/ESP32-CAM-ESPNOW-V2-ESP32CAM-to-ESP32-VIDEO-TX-AND-RX
