public final class RscMeasurement
- Object
- RscMeasurement
A decoded Running Speed and Cadence Measurement, characteristic
0x2A53.
Wire format
A flags byte – bit 0 stride length present, bit 1 total distance
present, bit 2 running rather than walking – then a uint16 speed and
a uint8 cadence, then the optional fields.
Cadence is in steps per minute, not strides
The profile transmits steps, so a runner at a typical 90 strides
per minute reports 180. Foot pods differ in which they display, and
halving the value to get strides is a decision for your UI, not
something this parser does silently. getStrideRatePerMinute() is
provided for when you want the other convention explicitly.
Speed arrives in 1/256 m/s and total distance in tenths of a metre.
Methods
public static RscMeasurement parse(byte[] value) | Decodes a 0x2A53 value. |
public double getSpeedMetersPerSecond() | Instantaneous speed in metres per second. |
public int getCadenceStepsPerMinute() | Cadence in steps per minute, as transmitted. |
public double getStrideRatePerMinute() | Cadence expressed in strides per minute – half the step rate. |
public double getStrideLengthMeters() | Stride length in metres, or Double.NaN when absent. |
public double getTotalDistanceMeters() | Cumulative distance in metres since the pod powered on, or Double.NaN when absent. |
public boolean isRunning() | true when the pod classified the motion as running rather than walking. |
public String toString() | Returns a string representation of the object. |

Method details
parse
public static RscMeasurement parse(byte[] value)Decodes a
0x2A53 value. Returns null for a malformed or
truncated payload; never throws.getSpeedMetersPerSecond
public double getSpeedMetersPerSecond()Instantaneous speed in metres per second.
getCadenceStepsPerMinute
public int getCadenceStepsPerMinute()Cadence in steps per minute, as transmitted.
getStrideRatePerMinute
public double getStrideRatePerMinute()Cadence expressed in strides per minute – half the step rate.
Provided so the conversion is explicit at the call site rather than
guessed.
getStrideLengthMeters
public double getStrideLengthMeters()Stride length in metres, or
Double.NaN when absent.getTotalDistanceMeters
public double getTotalDistanceMeters()Cumulative distance in metres since the pod powered on, or
Double.NaN when absent.isRunning
public boolean isRunning()true when the pod classified the motion as running rather than
walking.toString
public String toString()Returns a string representation of the object. In general, the toString method returns a string that “textually represents” this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@’, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + ‘@’ + Integer.toHexString(hashCode())
