    Connect multiple BME688 to a Wio terminal

    Hello,

    I am currently working on a project involving reading data from 3 BME688 sensors, sold by SeeedStudio, connected to a Wio terminal I2C port via a hub.

    I have trouble separating the sensors in my code but most importantly, I would like to access the raw sensor data, not the IAQ or Gas resistance, is is possible with the BME688?

    Sorry if my question is too simple, this is not my specialty.

    Hi ANTY, By setting the SDO pin to high or low level, you can identify two BME688 devices on the same I2C bus, but not the third BME688. You can use SPI bus to select multiple BME688 through CS.
