I apologise if this is clearly indicated somewhere, I couldn't find the answer.
I am wondering if someone could indicate which sensor fusion mode (NDoF or IMUPlus) is used in the MetaBase iOS app when selecting Euler Angles?
You can read the code, it's all open source:
let mode = magnetometer ? MBL_MW_SENSOR_FUSION_MODE_NDOF : MBL_MW_SENSOR_FUSION_MODE_IMU_PLUS
Which means its NDOF if the magnetometer is present.
Very good, thank you Laura
