I am aware that the BSEC library offers two sample rates by default - LP (every 3 seconds) and ULP (every 5 minutes). It also seems that - if the sensor is not read at sufficient frequency (e.g. the sensor is configured for LP mode but only read every 10 seconds) - the IAQ values are not updated. (IAQ accuracy remains at 0 and IAQ value and CO2 equivalent never change.) But I am working with a firmware in which the MCU is put to sleep for >> 5 minutes. Can BSEC_SAMPLE_RATE_ULP_MEASUREMENT_ON_DEMAND be used to overcome this minimum sample rate? (I have experimented with this mode briefly, but the call to updateSubscription() returns a BSEC_E_SU_WRONGDATARATE error - and I get the impression that this is not the use case that this mode is provided for.) I am currently using the Arduino BSEC library version 1, but am willing to switch to the BSEC2 library if necessary. I have prior experience with the lower-level C library also, and am willing to work with that again - but perhaps not if the library is simply not designed to work with sample intervals greater than 5 or 10 minutes. P.S. The goal is to allow the device running this firmware to sleep for 30 minutes at a time.
