Hello

I'm beginner with ESP32 and I don't know connect two ESP32 boards using whatever communication protocol E.g SPI, I2C. Someone give me a hand please with these topics. I tried to connect two ESP32 through SPI but it's fail. I think have a mistake in slave code because i don't know configure slave's address for acced with ESP32 master.

Regards.

hi Meca,
Check out this video, for Simplex ESP32 to ESP32.

BTW: the hx711-multi will not compile on Arduino IDE with a ESP32, still searching for a solution.

This is an alternative ESP32 to ESP32 method.
