I'm currently working on a project where I have connected an ATmega microcontroller to an ESP32 board using UART communication. The communication between the two devices is working fine, but now I want to update the firmware on the ATmega using the ESP32's Wi-Fi capabilities.
I'm unsure about the best approach to update the ATmega firmware over Wi-Fi using the ESP32 as a bridge. I would greatly appreciate any guidance or suggestions on how to achieve this.I haven't found a comprehensive guide or tutorial specifically addressing this scenario. Any advice, code snippets, or references to relevant documentation would be extremely helpful.
