Well, here is the problem:
I want to send a value from pressing a button on the Nextion tft display, to the arduino.
I can understand I need to use the "get" variable when the button is activated in the Nextion editor.
Then how do I read this value in the arduino code?
Any help will be appreciated.

will not keep repeating
I shouldn't, I am not librarian - was third in Free Chat List
Title is Getting Number Value From Nextion
Swap NexNumber to NexVariable
.getValue(&number) and .setValue(number);
Please review NexVariable.h and NexVariable.cpp in library code
Please review Nextion Instruction Set
In raw char format you need to send
and wait for answer as per Number 0x71 Return Data
0x71 0x00 0x00 0x00 0x00 0xFF 0xFF 0xFF
I hope I wasn't rude either
