Increase Serial speed

The standard transmission baudrate is 9600. Is it posible to change this in 115200?
If yes how to do that?

You can go up to 921600 baud. There are two ways to change the baud rate:
First, temporarily (won‘t survive power fail or reboot) by setting the „baud“ system variable to the desired value, for ex. baud=115200
Second, permanently by setting the „bauds“ system variable to the desired value, for ex. bauds=115200. This will make it the new default baud rate and the actual baud rate (in „baud“) will become the same after power cycle or reboot. All this is well documented in the Nextion Instruction Set (scroll down to the paragraph „system variables“) on the Nextion.tech website.

Tanks for the information. But where (place) can I set this bauds=115200?

Many possible paths:

  • connect the display to your PC and send the command from the command line
  • connect the display to your PC, start the Nextion Editor and launch its integrated debugger and send the command from the command pane
  • integrate the command in your hmi project’s startup code (the program.s tab)
  • and, and, and….
