Delay between arduino and nextion display

[ynsyildiz]

I send string data from the nextion screen to the arduino.I transfer the incoming data to a variable as int.there is no problem here.when I say send from the screen, it takes 1 second to come to the arduino.if I send 3 4 different data in a row, only 1 accepts the first one I send.
hardware: arduino uno 16mhz
baud rate : 9600 and 115200.
Is this normal or is it because the uno speed is low.
Thank you.

The delay you describe is not usual and is not because of the low baud rate. Without seeing your code no one can really help. Please read and follow the forum guide How to get the best out of this forum, especaially the bit about how to post code in code tags <code/> to make it clear and easy to read.

I have a Nextion tutorial here:

Using Nextion displays with Arduino

Introduction Nextion displays include either a resistive touch panel (RTP) or capacitive touch panel (CTP) and provide an easy way to create a touch screen interface, or human machine interface (HMI) for your project. The displays require a spare serial port to communicate with them. To get the best from them requires an understanding of how to drive them, and what works and doesn't work. The advice here is based on my work with multiple projects using Nextion displays with both PIC and Arduino…
