    We will recommend BMI270 for TWS use case.

    Hi Vincent,

    You said that BMI270 is for the wrist use cases. Sorry, but could you explain why you recommend the BMI270 for TWS?

    Yes, from the feature setting, BMI270 provide all wrist interrupt features. 

    But in sensor parameter,  BMI270 as our latest IMU provide high accelration parameters and also improved gyro parameters.   and overall power consumption is only 685uA for full operation mode (A+G). 

    This means in TWS general use case,  BMI270 can also fit into. 

    In the other hand,  we can also recommend BMA456 with triple tap for TWS use case.

    Both TWS use case are not considering the high bandwidth for bone detection.
