Solved: BSEC BME680 no IAQ output

MJ_kio · ‎04-11-2022

hi @BSTRobin ,

Inputs are exacty the same for WSP8266 Arduino example and for nrf product.
The only diferrecnce is that timestamp for nrf is always the same and for Arduino is passed from input to output.

Hi MJ_kio,

For "The only diferrecnce is that timestamp for nrf is always the same and for Arduino is passed from input to output.", do you mean timestamp under nrf platform always the same value when you read timestamp from nrf platform?

MJ_kio · ‎04-11-2022

hi @BSTRobin ,

Yes, on nrf platform timestamp bsec_outputs[index].time_stamp is always the same, even after multiple measurements, whereases on Arduino example mentioned timestap is equal to timestamp given with measurements.

Hi MJ_kio,

1. I mean your platform's timestamp, not BSEC output timestamp. You cold check if the following time stamp value change or not?
/* time stamp */
int64_t time_stamp = (int64_t)(m_clock->getMillisecondsSinceBoot()) * INT64_C(1000) * INT64_C(1000); // nanoseconds;

2.You can check the function named "bme680_bsec_process_data" which has a switch. Helping me to find where does "bsec_outputs[index].sensors" get assigned? We found such as "case BSEC_OUTPUT_IAQ“ .etc didn't run to assign iaq lead to IAQ output is 0 in the log.

Hi @BSTRobin ,

1. I print timestamp before each measurement, it changes properly. Moreover tieme to sleep is properly calculated, I use it, it uses time stamp as well.

2. I have 5 outputs from function (IAQ is missing)
