I'm a beginner in arduino and nextion and I'd like some explanation...
By just using the serial monitor of the arduino IDE, with my project code, I can only send data to nextion but not the data from the nextion.
However as I test the code of this topic http://support.iteadstudio.com/support/discussions/topics/11000000869
I thought the monitor was displaying everything happening in the serial (after setting the correct baud rate) but it's not that simple.
Excuse my ignorance but could someone explain why I get those results ?
i made the same question but none can answer it :/
