    BME680 BSEC Samping Rate

    BME680 BSEC Samping Rate

    Hi,

    I am planning to use a BME680 for a desk based "info terminal" which should also show some air quality information. Currently, I am using the BSEC library and everything is fine.However, I've noticed that there are only two sampling rates BSEC_SAMPLE_RATE_LP and BSEC_SAMPLE_RATE_ULP with 3s and 300s sampling time, respectively. Is it possible to use other sampling rates, like 30s or 60s?

    My device will run only when I am at work, so at max 8 to 9 hours each day. During my tests I also noticed that the IAQ accuracy only goes up to 1 after ~200s (for LP mode; 20mins for ULP mode - this is mentioned in the data sheet). WIll the BME680 remember historical low and highs, so it will achieve higher IAQ accuracy values? Otherwise,  my plan to use it on my work desk as an air quality monitor will be useless, I guess.

    Thanks alot,

    Matt

    "I believe it is technically possible to reach ~60s sampling rate by using the ULP+ feature of BSEC"

    I can't find any documentation, how would one go about doing this?
