    Hi to community,

    First of all, Huge thanks to BOSCH for BNO055, Its awesome and I really enjoy working with it.

    I have been working with different IMUs and AHRS systems for a while, Now that I need to manipulate and edit some in AHRS matrices, which unfortunately I don't have access on BNO055 which is ok and I highly respect the company policy for that, so I decided to use BNO055 raw data to obtain smooth and accurate output with some modifications. 

    So I started to implement a Kalman Based Quaternion Sensor Fusion Algorithm and I came up with some questions and thought the best place to ask is here.

    1.What should I do exactly to obtain a smooth quaternion output?

    2.Which ODR and FS setting should I set for my sensor?

    3.In which frequency should I run my sensor fusion algorithm?

    4.and any other important thing that may help

    Regards,

    Mason

    Hello Mason_Safavi,

    Could you describe your detailed application scenario and requirement?

    Thanks for responding, @
    Here is what I'm trying to achieve: I'm trying to use BNO055 with Adafruit_AHRS library which includes Kalman Based NXP Sensor Fusion Algorithm for obtaining the same BNO055's Smooth Quaternion output.
    But I don't know which exact setting I should set to achieve that.(ODR,FS,Filter Frequency)

    Hello Mason_Safavi,

    If you don't know how to config sensor setting, you could refer BNO055 example code in github.
