Hello
For some reason the example doesn't work, am I doing something wrong?
In this example, there was no overlay file, which I made myself.
I use a sensor: https://www.mikroe.com/lightranger-2-click

};
and prj.conf:

I have also used, for example, the ENS210 sensor from the same manufacturer and it has worked beautifully.
Thank you.
