Delay between arduino and nextion display

[PerryBebbington]

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…
