BME688 bsec_do_steps returns value 5

[jadeja14890]

Hello,

We are using BME688 sensor with nrf52840 controller.BSEC library used is having version 2.0.6.1.

We are facing problem with getting output using bsec_do_steps. Configuration file used is "bsec_sel_iaq_18v_4d" and mode set is HIGH PERFORMANCE mode.

Calling bsec_do_steps API at every "bsec_bme_settings.next_call" interval gives return value 5 i.e BSEC_W_DOSTEPS_GASINDEXMISS

Can anyone help why we are facing this issue

Thanks

Hello jadeja14890,

You could see "BST-BME688-Integration-Guide-AN008-06.pdf" under BSEC 2.0.6.1 package, and check step by bstep if you have correct SW integration.
