Enthernet Code
I need a circuit to download the firmware inside esp32 and the pin used.
@youcef_ali connect a USB-to-Serial converter to the ESP32's RX (GPIO3), TX (GPIO1), GND, and 3.3V pins. Hold GPIO0 (BOOT) low and press the reset button to enter flash mode. Then, use a tool like esptool.py to upload the firmware.
