Problem BSEC_OUTPUT_GAS_ESTIMATE_1

[steven_bsec]

When enable BSEC_OUTPUT_GAS_ESTIMATE_1,  sample_rate is BSEC_SAMPLE_RATE_SCAN, bsec_update_subscription function return BSEC_E_SU_SAMPLERATELIMITS.

But When disable BSEC_OUTPUT_GAS_ESTIMATE_1, bsec_update_subscription function return BSEC_OK.

Why is that?

Hi steven_bsec,

Did you run with latest BSEC software package https://www.bosch-sensortec.com/software-tools/software/bme688-software?

[steven_bsec]

Yes , I use bsec2-4-0-0_generic_release_23012023. 

Now,  the problem is that when enable BSEC_OUTPUT_STATIC_IAQ with BSEC_SAMPLE_RATE_LP and BSEC_OUTPUT_GAS_ESTIMATE_1 with BSEC_SAMPLE_RATE_SCAN together, bsec_update_subscription return BSEC_E_SU_SAMPLINTVLINTEGERMULT(-16). 

If I want to enable BSEC_OUTPUT_STATIC_IAQ and BSEC_OUTPUT_GAS_ESTIMATE_1 together , what should i do?

Hi steven_bsec,

Currently, the BSEC library supports only one output of IAQ or gas identification, and does not support both of them output in one routine.
