Bme680 bsec iaq accuracy is always 0

[Sridhar]

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"?

Hi,

Yes all the condition I followed in document. Still it is the same issue.

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.
