I Have my own developed PCB with ESP32S and Ethernet W5500 onboard
Now I need to send picture from CAM to ESP32 by UART and then from ESP32 to local server by Ethernet
Kindly ask you to share ideas or any link for such topic
I’m not familiar with those specific subjects.
Take a look at the following topic for sending pictures via UART: https://forum.arduino.cc/t/transfer-pictures-from-esp32-cam-to-esp32-via-serial/647488/4
I also don’t have any resources using ethernet and the ESP32.
I’m sorry that I can’t help much.
