Hello,

i'm using an BME680 with a STM32L462VE and i have Problems with adding new Virtual Sensor Output Signals.

I always get following status from 

/* Call bsec_update_subscription() to enable/disable the requested virtual sensors */
status = bsec_update_subscription(requested_virtual_sensors, n_requested_virtual_sensors, required_sensor_settings,
&n_required_sensor_settings);

BSEC_E_SU_SAMPLINTVLINTEGERMULT = -16, /*!< The sample_rate of the requested output (virtual) sensor passed to bsec_update_subscription() is not correct */

/* note: Virtual sensors as desired to be added here */
requested_virtual_sensors[0].sensor_id = BSEC_OUTPUT_GAS_ESTIMATE_1;
requested_virtual_sensors[0].sample_rate = sample_rate;
requested_virtual_sensors[1].sensor_id = BSEC_OUTPUT_GAS_ESTIMATE_2;
requested_virtual_sensors[1].sample_rate = sample_rate;
requested_virtual_sensors[2].sensor_id = BSEC_OUTPUT_GAS_ESTIMATE_3;
requested_virtual_sensors[2].sample_rate = sample_rate;
requested_virtual_sensors[3].sensor_id = BSEC_OUTPUT_GAS_ESTIMATE_4;
requested_virtual_sensors[3].sample_rate = sample_rate;
requested_virtual_sensors[4].sensor_id = BSEC_OUTPUT_RAW_PRESSURE;
requested_virtual_sensors[4].sample_rate = sample_rate;
requested_virtual_sensors[5].sensor_id = BSEC_OUTPUT_RAW_TEMPERATURE;
requested_virtual_sensors[5].sample_rate = sample_rate;
requested_virtual_sensors[6].sensor_id = BSEC_OUTPUT_RAW_HUMIDITY;
requested_virtual_sensors[6].sample_rate = sample_rate;
requested_virtual_sensors[7].sensor_id = BSEC_OUTPUT_RAW_GAS;
requested_virtual_sensors[7].sample_rate = sample_rate;
requested_virtual_sensors[8].sensor_id = BSEC_OUTPUT_RAW_GAS_INDEX;
requested_virtual_sensors[8].sample_rate = sample_rate;
requested_virtual_sensors[9].sensor_id = BSEC_OUTPUT_IAQ;
requested_virtual_sensors[9].sample_rate = BSEC_SAMPLE_RATE_ULP;
requested_virtual_sensors[10].sensor_id = BSEC_OUTPUT_STATIC_IAQ;
requested_virtual_sensors[10].sample_rate = BSEC_SAMPLE_RATE_ULP;
requested_virtual_sensors[11].sensor_id = BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_TEMPERATURE;
requested_virtual_sensors[11].sample_rate = BSEC_SAMPLE_RATE_ULP;
requested_virtual_sensors[12].sensor_id = BSEC_OUTPUT_SENSOR_HEAT_COMPENSATED_HUMIDITY;
requested_virtual_sensors[12].sample_rate = BSEC_SAMPLE_RATE_ULP;

i have no idea why.

Hi Reamer, 

Since BSEC_OUTPUT_GAS is for BME688 gas scanning, you have to remove it. 

Please use below one. 

/* note: Virtual sensors as desired to be added here */
requested_virtual_sensors[0].sensor_id = BSEC_OUTPUT_IAQ;
requested_virtual_sensors[0].sample_rate = sample_rate;
requested_virtual_sensors[1].sensor_id = BSEC_OUTPUT_RAW_PRESSURE;
requested_virtual_sensors[1].sample_rate = sample_rate;
requested_virtual_sensors[2].sensor_id = BSEC_OUTPUT_RAW_GAS;
requested_virtual_sensors[2].sample_rate = sample_rate;
requested_virtual_sensors[3].sensor_id = BSEC_OUTPUT_RAW_HUMIDITY;
requested_virtual_sensors[3].sample_rate = sample_rate;
requested_virtual_sensors[4].sensor_id = BSEC_OUTPUT_STATIC_IAQ;
requested_virtual_sensors[4].sample_rate = sample_rate;
requested_virtual_sensors[5].sensor_id = BSEC_OUTPUT_CO2_EQUIVALENT;
requested_virtual_sensors[5].sample_rate = sample_rate;
requested_virtual_sensors[6].sensor_id = BSEC_OUTPUT_BREATH_VOC_EQUIVALENT;
requested_virtual_sensors[6].sample_rate = sample_rate;

Hi Minhwan,

thank you, now it works.
