Yes! Thanks a lot! :-)

Sorry!
For some reason I completely overlooked that you wanted to connect two devices together.

So the answer is yes! Get a Grove cable:

Remove/cut the the red (+5v) wire and setup the UARTs on both devices with "crossover" pin-config.
I.e.:

Device A UARTx Tx=32 Rx=26 Device B UARTx Tx=26 Rx=32

or vice versa.

I'm not sure what you mean by "using interrupt", but you could (with same cable) define say pin 32 as output on device A and the same pin as an input defined to an interrupt on Device B and then perhaps the opposite with Pin 26

@kmk68 RS485 communication would would work, is designed for this sort of thing, but also cheaper

Ok, Solved.
On cleared Arduino IDE, I install no M5Stack library, but "Unified M5Stack".
And ONLY M5Stack boards.
And other my modules ESP32 - WROOM, MH ET mini kit, Wemos D1 I can
programing as "M5Stack ESP32" and its work without any other ESP32
boards and libraries.
