Hello Hello doppio-R,
By default, CO2 and VOC was not in output list for this example. You could modify the following code to enable CO2 and VOC output.
#define NUM_USED_OUTPUTS 10
static bsec_library_return_t bme680_bsec_update_subscription(float sample_rate) { ... requested_virtual_sensors[8].sensor_id = BSEC_OUTPUT_CO2_EQUIVALENT; requested_virtual_sensors[8].sample_rate = sample_rate; requested_virtual_sensors[9].sensor_id = BSEC_OUTPUT_BREATH_VOC_EQUIVALENT; requested_virtual_sensors[9].sample_rate = sample_rate; ... }
