BME688 Reading Gas zero values

[hrishnspl]

Hello,

I have integrated BME688 sensor with my microcontroller. I have followed all the steps provided in the API code. Whenever I start reading the data I am able to read the Temperature, Pressure, Humidity values but the gas adc reading always comes as zero. I also tried to check the validity of the gas but it is also reading as zero.

Could you please help me in resolving this. Where can I go possibly wrong.

Hi hrishnspl,

You could refer attached BME688 example code which used sensor API on github: https://github.com/BoschSensortec/BME68x-Sensor-API

And check if you migrate example correctly.

Hi,

As mentioned already, we have integrated the same code as mentioned in the github. But the gas resistance is zero. The settings used is same as the one mentioned in the code. We are able to read the temperature, humidity, pressure values correctly.

Also how should we confirm that the MOx sensor is reaching the set target temperature?

Hi hrishnspl,

Can you compare your code with the reference code? The same code cannot get different results.
