Hi Alexandro, there is a code example under "/home/pi/demo".
You can customize this to your liking. In this script an interruption of the internet connection is tested cyclically as an example.
The watch dog timer will be reset until the internet connection is not possible.
So your task is to adapt this script or to write the image 6 of the variable "RevPiLED" cyclically in your code instead of the script itself.
This writing you omit, as soon as your error condition occurs - That is also already everything.
