    BME 680 IAQ stuck at 25 and accuracy always zero on Arduino MKR1000

    BME 680 IAQ stuck at 25 and accuracy always zero on Arduino MKR1000

    Recently I have acquired from Adrafuit two BME680 boards for my Indoor Air Quality Monitor station project. 

    After following the  BSEC-Arduino-library README file, I have compiled the library with success on the Arduino MKR1000 using Platformio.

    However, after running this library for 24 hours, the IAQ, eVOC and eCO2 read values are always the same. The accuracy retrieved by the sensor is stuck at 0, and I don't know how to fix this. I have already tested the two different sensors and nothing has changed.

    To mislead, I have downloaded the official library from https://www.bosch-sensortec.com/ (which is currently on version 1.4.8.0) and I have replaced the compiled libalgobsec.a for the Cortex-M0+ processors, but the problem persists. Temperature, humidity, pressure, and gas values look good so it is just a problem with the internal calibration of the sensor... 

    Any suggestion? Thank you.
