Measuring VL6180X with close distances

Hey,

I am having the VL6180X Satellites sensor for ranging measurements. After connecting it, I receive some measurement values - but they are the wrong ones. The sensor isn't reacting to changes in a distance between 0mm and ~50mm. It keeps showing me the value "4 mm". Beyond that distance of 50 mm, the values start increasing, which is fine.

Is there anything I am forgetting? I have set the Offset to 0 mm. The range-ignore features and the early convergence are disabled (by register 0x02D). I performed the measurements in the darkness.

 

Thanks in advance!
