Dimming Nextion displays with Arduino

Other Hardware Displays
1

I have to set the brightness of my nextion NX3224TO24, interfaced to the ESP8266 serial port. What is the command to set the dim variable with or without a library?

I answer myself:

Serial.print("dim=25");
Serial.write(0xff);
Serial.write(0xff);
Serial.write(0xff);

dim
dims Nextion
Backlight dim=32, dims=100
Sets the backlight level in percent
min 0, max 100, default 100 or user defined
Note: dim=32 will set the current backlight level to 32%.
using dims=32 will set the current backlight level to 32% and save this to be new power on default backlight level, persisting until changed.
