    How do you initialize BME280 for I2C

    Hi, i want to readout the data of my BME280 environment sensor but somehow i don't get any results. I only found, that you have to connect CSB to VDDIO, for I2C to be active and pulled SDO to GND.

    What else do i have to do?

    Thanks for your support! 🙂

    Hello nicoheggli,

    For BME280 I2C hardware connection, you could refer the following diagram froom BME280 datasheet.

    Thanks, I've already made the hardware connections but I still have trouble with initializing the sensor. Which values have to be set for the sensor to be initialized?
