    BSEC 2.0 + BME688 to detect BSEC_OUTPUT_GAS_ESTIMATE_1

    BSEC 2.0 + BME688 to detect BSEC_OUTPUT_GAS_ESTIMATE_1

    Hi, I'm using BSEC 2.0.6.1 and BME688 sensor with a config generated using BME AI Studio. The config is a simple coffee detection algorithm trained using BME AI studio.

    Unfortunately I am having issues using the BSEC 2.0 library. I have implemented my code according the bsec integration guide and the bsec example. 

    Problems:

    1. I am unable to use a sample rate other than BSEC_SAMPLE_RATE_HIGH_PERFORMANCE when calling bsec_update_subscription() with BSEC_OUTPUT_GAS_ESTIMATE_1 enabled.

    2. If BSEC_SAMPLE_RATE_HIGH_PERFORMANCE is used, I am not getting new information for requested outputs that relate to gas measurement. The aqi, gas_percentage and gas_estimate_x values are not changing.

    Questions:

    1. Do you have sample code for using bme-ai solution with bsec2.0? 

    2. What limitations apply to the sample-rates requested using bsec_update_subscription?

    It seems as if others are also facing this issues.

    Thanks,

    Akmal

    Hello AkmalSQ,

    Is there any error or warning code on your side?

    The example code in BSEC2 release package is verified and can be used for start up.

    Please make sure you used the bsec_serialized_configurations_selectivity configure string. And for selectivity solution, when gas estimated is requested, we can only use BSEC_SAMPLE_RATE_HIGH_PERFORMANCE, otherwise gas estimated will not be updated.

    Could you give feedback?
