UART communication pair of M5Stack’s’


I implemented UART communication between M5Stack and M5Stack.
That works by really simple codes.

This is sending something over UART.

This is receiving things coming over UART.

If you say “communication with M5Stack and M5Stack”, it’s easier connecting with “using WiFi”, of course. But on this time, I’m intentionally using UART. Actually there are bunch of cases “cannot use WiFi” because of heavy interference, less infrastructure or any educational cases (eq. ease of understanding)

I hope that it could fit in any case which I don’t know 😉
