bme68x_set_heatr_conf() function issue

[steven_bsec]

Hi,

I use STM32 to read bme688 IAQ.I write software as below example.

If I call the bme68x_set_heatr_conf() function, the IAQ is always 25 and the humidity is always 100%, but the temperature and air pressure are normal. If I don't call this function, both IAQ and humidity are normal. what is the reason?

If the function bme68x_set_heatr_conf() is not called, will the result be inaccurate?

Hi steven_bsec,

The original code works. Have you modified anything in "BSEC_2.0.6.1_Generic_Release_04302021" package?

[steven_bsec]

I no modified BSEC_2.0.6.1_Generic_Release_04302021 package.The file I use is as below.

I want to confirm two questions:
1. What are the possible reasons? Can't the sensor reach heatr_temp?
2.What is the effect of not calling the bme68x_set_heatr_conf() function

It mean that the bme688 needs to be heated to 320 degrees Celsius?

Hi steven_bsec,

Example code used this function to configure sensor with parameters. This function is needed.

but when i call bme68x_set_heatr_conf  ,the AQI  does not change and humidity is too high .
