i tried to write myNex.begin(115200);
but screen can' read anything.

Hello,

This could be due to different baud rates. Arduino has 115200 and Nextion something else, possibly 9600.

In the Preinitialize Event of the first page loaded on Nextion, write:
baud=115200 (this changes the baud rate of Nextion to 115200 only for that HMI file)
or
bauds=115200 (this changes the default baud rate to 115200)

Try to do this and let me know

thanks a lot, works
