    BME680 + NRF9160 in ZephyrRTOS

    Hello,

    There is a BME680 driver in Zephyr, but no support for the IAQ. So I want to integrate BSEC to nrf9160 using zephyr, but it's cortex M33.
    I couldn't see the cortex-M33 library in BSEC github.
    How can I sort it out?

    Thank you.

    I have found the way to solve this using nrf connect sdk. There was an example for asset_tracker.
    Sorry to interrupt you. 😉

    Hi, I am interested in IAQ from BME688 on NRF9160 ZephyrRTOS, the drivers for BME680 should also work with BME688. 

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

    But the gas values from above saturate at 250. As per the datasheet, this should go up to 500. Whatever I do - putting it close to Alcohol, surrounding it with ethanol, it does not go beyond 250. 

    Any hints?
