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 BSTRobin, I get warning code when i call `bsec_sensor_control(time_stamp, &sensor_settings);` in bsec_iot_loop(); My program language is c. I already migrate my platform: using esp32 hal api and BSEC API for esp32s3. There is no delay function in bsec_iot_loop: void bsec_iot_loop(sleep_fct sleep_n, get_timestamp_us_fct get_timestamp_us, output_ready_fct_t output_ready,
state_save_fct state_save, uint32_t save_intvl)

Yes, I already migrate to esp32s3 use libalgobsec.a of esp32s3 and esp32s3 hal api. I use c language.
