Static IAQ Behaves Uncertainly when the IAQ Accuracy set to "1"

[msalmankhan]

Hello Bosch!
I have running multple BME680 sensors which are currently report data, and I found that some sensors have drops their Static IAQ values to "zero" when the IAQ Accuracy is set to "1", is this behaviour is normal , as you can see the Image below, 
I am currently using LP mode of sensors.
After 5 mins the IAQ accuracy is set to "1" for all sensors but some sensors have drop their Static IAQ value to "0".
Thanks

Hi msalmankhan,

1.What is BSEC version you used? And which example code you run、
2.Could you run it for more time and see it again?

This is the version currently i am using marked with red box, I have checked again this time the behaviour is different then already shown in the Static IAQ curves.

Hi msalmankhan,

Suggest you refer attached example code which runs BSEC 1.4.8.0 well on STM32.
