I bought big amount M5-stick, and additional devices. It was surprise box, 2x2x2 meter box and include "electronics".
I found one PuppyC and Stick. I found it special burner for Puppy+Stick. Now I can see "IIC_puppy" on display. Also I can start M5Flow.
But... all what I try do in M5flow, it ask always "wrong api-key". I try all possible "12345678" etc etc, also I try found any numbers from stick or puppyC. Nothing.
What is this "api-key"? How I can invite it? I try use google also, but.... again, nothing.
