Hello everyone,
i just wrote a code For Arduino Cloud using VS Code for my nano 33 iot board. While compiling i got error referring to include SNU.h after i included it worked. I just want to know the function of SNU.h .
Please post your sketch and the full error message, using code tags for both
the library loads the update binary over network and applies it. it works as a second stage bootloader preppended to your sketch
