Summary:

The RSC Measurement characteristic (RSC refers to Running Speed and Cadence) is a variable length structure containing a Flags field, an Instantaneous Speed field and an Instantaneous Cadence field and, based on the contents of the Flags field, may contain a Stride Length field and a Total Distance field.
