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?
The original code works. Have you modified anything in "BSEC_18.104.22.168_Generic_Release_04302021" package?
I no modified BSEC_22.214.171.124_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?
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 .
