I'm not sure whether this is because I've already collected test data (which I have flagged, and won't use), or if it's a bug. Thanks for your help!

But then we found that some parameters do only provide zero values, regardless of the sample we put in the clip, including the calibration sheets.

External sensor integration

By Andriy Herts, Nataliia Herts

Hello, folks! I have been using MultiSpeQ for several years. I tried to integrate into firmware external sensors.

API address
