BSEC with ESP-IDF not getting IAQ

[manuislet]

Hi all,

I have succesfully integrated in ESP-IDF all required files to run BSEC and BME680, however, after many attemps to get AIQ and other calculated data, i only have temperature, humidity and  pressure, other values such as IAQ, IAQ accuracy, VOC... remains at 0 (sometimes 0.25). I am currently loading configuration for "bme680_iaq_33v_3s_4d".

Another question, is there any way to executte bsec on demand? I mean, get temp, IAQ, etc every 5 minutes or so and not executing continuosly (avoid using bsec_iot_loop)

Find attaches my main.c, all other files from Bosch library remains untouched. Also here you can find my project structure.

Extra info:

-BSEC version: 2.4.0.0 generic release

-BME68x sensor API version: 4.4.8

Thanks in advance

Hi manuislet,

It seems that your development environment uses C language, right?

[manuislet]

@BSTRobin yes, im programmig the microcontroller using C. I have added main.c file to first post where you can see BSEC implementation

[manuislet]

@BSTRobin any recomendation?

Hi manuislet,

I upload BSEC2.4.0.0 example code on STM32 for your reference, which run with C language and support to output IAQ and estimate.
