Thanks a lot for the detailed answer and for making this clear. As far as I understand now, the configuration string I asked about here is used to tell the bsxLite API the sensor's default settings. The user can than decide to : 1. Set up the sensor itself with its default settings for accel&gyro-range, fetch its data and feed it to the bsxLite API as it is. or 2. Use whatever range he wants, fetch the sensor's data and convert it to the sensor's default LSB/dps or LSB/mg range before feeding it to the bsxLite API. I still wonder how to find the default values for the magnometer (bmm150) are. According to the Datasheet the resolution is 0.3 microTesla. Bmm150's api returns 1lsb/microTesla. According to this user this is not a valid input, as he used the "raw" api data, which is 1lsb/(1/16) microTesla, which again is different from the sensors resolution. Cheers!
