IAQ from BME688 on NRF9160 ZephyrRTOS

[DDVi]

Hi, Zephyr already has support for BME680. We are interested in IAQ from BME688 on NRF9160 ZephyrRTOS, and have been using this:

https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/sensor/bme680/bme680.c#L383

But the values saturate at 250. Shouldn't it go up to 500? It would go up to 250 in rather benign situations and flatten there. I have tried putting it close to Alcohol, surrounding it with ethanol but can only get a flat line at 250. 

Many thanks for any hints?

Hi wassfila,

You could refer the integration guide and ensure you migrate BME68x software to your platform correctly.
