I have a problem with netxtion communication. Everything worked just fine but today there was a communication problem.
arduino to nextion data is not going but when i touch and triggered attachPop, is working and print serial. I Change the serial port but get same result.
When i test on nextion editor simulator, this work is just fine. Simulator change the label and values, and simulator send to arduino.
Nextion > Arduino data SENT
Arduino > Nextion data ERROR
Arduino > Simulator SENT
Simulator > Arduino SENT
Do I make a mistake in the arduino?
PS: Used itead nextion arduino library.
