My question could sound simple or stupid, but I just want to make things clear. I'm using accelerometer in an app, and I want to know how can I use the new iPhone 5S M7 motion co-processor, at the moment I'm receiving accelerometer data using CoreMotion.framework method - (void)startAccelerometerUpdatesToQueue:(NSOperationQueue *)queue withHandler:(CMAccelerometerHandler)handler;, is it enough? This is an universal approach (good for devices which doesn't have M7 co-processor)? Or I must do something else? Where can I read and learn about how to use the new M7 processor in an app? Thanks.
M7 co-processor will enable applications to be aware of what type of
movement the user is experiencing, such as driving, walking, running
or sleeping. then Application could be the ability to do indoor tracking and mapping.
The Apple M7 co-processor collects, processes and stores sensor data
even if the device is asleep, and applications can retrieve data when
the device is powered up again. This will reduce power draw of the
device and save battery life
