BME688 how to decide the task sleep time of bsec_iot_loop() on a multitasking system

[brianchen]

Hi Bosch team,

My system controls external I/O, and running scan mode for gas estimation of BME688.

The lib is v2.4.0. Checking the integration guide (session 1.3.2), BSEC needs to read sensor every 35 ms ? 

That means in bsec_iot_loop() we can only let the task sleep for <35ms. 

What if we let the task sleep extend to 200 ms? Will this influence the gas estimation accuracy? or cause BSEC unstable? 

Thank you!

Hi brianchen,

Thanks for your inquiry.
If you run the gas scanning mode of BSEC 2.4.0.0, you can only follow the process of the reference code, as it is a requirement of the BSEC algorithm and its architecture cannot be modified.
