#56430 Hello,

I have flashing the ESP OTA working great using Arduino IDE.

I was wondering if I could also flash an Arduino Pro Mini that is connected to the ESP as an i/o expander THROUGH the ESP OTA ?


Somehow have ESP know when to flash itself vs flash the connected pro mini.

Thanks,
Rey

However, that project just uses the ESP for wifi and the Arduino is master.

I'd like to load a firmware file onto the ESP free space and instead of it then overwriting the ESP firmware, it's flashed onto the Arduino.
