I’m having the same issue as another user where I can’t get the ESP32-Cam to communicate with the UNO board. They’re solution to the problem was to reflash their ESP32-Cam using https://github.com/sunfounder/ai-camera-firmware This solved their issue and I believe it would solve mine as well but despite looking online I cant figure out how this is done. Any help is appreciated!
Also, this is a replacement ESP32-Cam to my original one that came with the GalaxyRVR
