    After 5 minutes IAQ changes but IAQ accuracy is 0 only still after half an hour.

    When it will also change?

    Hello Sridhar,
    There was a integration guide file after you download BSEC package. Could you check "3.2 IAQ output does not change or accuracy remains 0"?

    Immediately after while(1) in bsec_iot_loop(), printing both timestamp, next_call

    sensor_settings.next_call 52803000000000
    time_stamp 52800000000000000

    sensor_settings.next_call 52806000000000
    time_stamp 52803000000000

    sensor_settings.next_call 52809000000000
    time_stamp 52806000000000000

    sensor_settings.next_call 52803000000000
    time_stamp 52800000000000

    sensor_settings.next_call 52806000000000
    time_stamp 52803000000000

    sensor_settings.next_call 52809000000000
    time_stamp 52806000000000

    sensor_settings.next_call 52812000000000
    time_stamp 52809000000000

    sensor_settings.next_call 52812000000000
    time_stamp 52809000000000

    sensor_settings.next_call 52818000000000
    time_stamp 52815000000000

    I can see everytime it is going through 3000ms. But iaq accuracy is 0 always.
