If you get the following print you are out of the heap memory needed to start the sensor:
(E) (rss_integration) Out of memory
The amount needed depends on the configuration that you have chosen. In general, the memory needed depends on:
* The amount of sensors you are using
* The length that you are sweeping
* The downsampling factor you are using
Before you are submitting an issue and asking, please check if it works by changing one of the settings above. Depending on your MCU, you might need to split your measurements in several measurements instead of a single one. I.e, instead of measuring from 0-2 meters, you might need to make one measurement from 0-1 meter and then another one between 1-2 meters.
