How to use Configurations for BSEC library?

[Mark-Walen]

I am using esp32s3 with bsec lib v2.4.0.0. develop environment program language is c. I want to use bme680_iaq_33v_300s_4d config. I copied bme680_iaq_33v_300s_4d directory to my project and then include bsec_iaq.h. write config_load function:

uint32_t config_load(uint8_t *config_buffer, uint32_t n_buffer)
{
    memcpy(config_buffer, bsec_config_iaq, n_buffer);
    return n_buffer;
}

 but this do not work. Its  smaple period is not 300 seconds instead 3 seconds.The sample rate I am using is BSEC_SAMPLE_RATE_LP. Should I replace BSEC_SAMPLE_RATE_LP to BSEC_SAMPLE_RATE_ULP?

Hi Mark, 

Yes, you should use BSEC_SAMPLE_RATE_ULP mode, not LP for 300s. 

Also, please make sure that you are using s3 library. 

Here is the right path. 

\BSEC2.4.0.0_Generic_Release_23012023\algo\normal_version\bin\esp\ESP32_s3

Thank you.
