Hi, I’m using the BME680 with the BSEC library. In the provided examples, the endless loop in the bsec_iot_loop() function is used in the main code to query sensor settings, apply them, and process the measured data. Since my application has other work to do during BME680 measurement, how can I do it if the code is stuck in an infinite loop? Is there another way to get BME680 measurement without running the bsec_iot_loop() ? Thanks. ... View more

Hi, I’m using BME680 with the BSEC library (lite version). The values of IAQ, bVOC and CO2e remain the same all the time. I'm using the bsec_integration.c sample code. Searching in other threads here, I found that the outputs of eCO2 and bVOC are not enabled by default, so it has to be set in the function bme680_bsec_update_subscription(). Into bme680_bsec_update_subscription() I added:     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; And I changed the value of NUM_USED_OUTPUTS and BSEC_MAX_PHYSICAL_SENSOR from 8 to 10. After that, I started getting values of eCO2 and bVOC but those values never change, as we can see in the log below:   P: 87877,000| GAS: 61936,000| T: 17,844| rH: 65,872| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87879,000| GAS: 62165,000| T: 17,844| rH: 65,916| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87877,000| GAS: 62028,000| T: 17,844| rH: 66,028| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87879,000| GAS: 62304,000| T: 17,854| rH: 66,146| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87877,000| GAS: 22818,000| T: 17,864| rH: 66,173| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87881,000| GAS: 12577,000| T: 17,904| rH: 66,358| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87881,000| GAS: 10785,000| T: 17,964| rH: 66,565| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87883,000| GAS: 2768,000 | T: 17,994| rH: 67,229| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87877,000| GAS: 3333,000 | T: 18,054| rH: 67,974| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87879,000| GAS: 3007,000 | T: 18,104| rH: 68,384| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87874,000| GAS: 3468,000 | T: 18,154| rH: 68,729| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499 P: 87879,000| GAS: 6773,000 | T: 18,204| rH: 68,964| IAQ: 25,000| Static IAQ: 25,000| CO2e: 500,000| bVOC: 0,499   Please note that the value of gas is changing but IAQ, bVOC and CO2e remain the same.
