    BMA456 Step Counter and Raise-to-wake Optimal ODR

    Hello,

    I am just wondering if the Step Counter for BMA456 has a optimal ODR requirement? My application needs a 25Hz ODR to function correctly, does that mean the step count and Raise-to-wake is unusable?

     

    Cheers,

    William

    Hello William, 

     

    We recommend to use ODR 100hz for step counter, but 25hz technically works. 

    We don't block it. 

    However, 25hz step counter accuracy could be worse than 100hz's. 

    Therefore, you need to test whether 25hz step counter meets your performance requirements. 

    Thanks,

    Thanks for the prompt reply Minhwan! What about raise-to-wake, do you also recommend ~100Hz ODR?

     

    Cheers,

    William

    Hello Wiliam, 

     

    What is the raise to wake? 

    Except tap sensing, all interrupts' feature should work with 100hz ODR 🙂 

    Thanks,
