Detailed Description

Represents the most commonly used data available from the ANT+ Stride sensor.

ANT+ sensors send data in multiple packets. The WFFootpodData combines the most commonly used of this data into a single entity. The data represents the latest of each data type sent from the sensor.

Property Documentation

- (float) accumulatedDistance
readwritenonatomicassign

The accumulated distance measurement.

When available, this value is similar to the WFFootpodRawData::distance value, but with a larger roll over value.

- (ULONG) accumulatedStride
readwritenonatomicassign

The accumulated stride count.

When available, this value is similar to the WFFootpodRawData::strideCount value, but with a larger roll over value.

- (float) cadence
readwritenonatomicassign

The measure of strides accumulated in time (strides per minute).

- (float) instantaneousSpeed
readwritenonatomicassign

The instantaneous speed in meters per second.

- (BOOL) isDataStale
readnonatomicassigninherited

TRUE if data is considered stale, otherwise FALSE.

- (float) lastTime
readwritenonatomicassign

The time of the last distance and/or speed computation.

Time starts when SDM is powered ON and continues until it is powered OFF. The integral component of the time data from the sensor is a single byte. Therefore, the time value will roll over after 256 seconds. This should be taken into account when calculating time offsets.

- (WFConnectorSettings*) settings
readnonatomicassigninherited

Gets the persistent settings for the Wahoo API.

- (NSTimeInterval) timestamp
readwritenonatomicassign

The real-time timestamp for data from the sensor (as an offset from the Cocoa reference date).

Time values from the sensors are implemented as an offset in seconds between the time when the sensor is turned on and the time when a data sample is taken. This value is typically a 16-bit unsigned integer in units of 1/1024 second. The rollover is then 64 seconds.

A base real-time value is stored when the first sample from the sensor is received. The timestamp of each subsequent sample is the base time value offset by the time value offset from the sensor. If the time between samples is greater than the rollover time, the base time value is set to the time the first sample after the delay is received.

- (BOOL) timestampOverflow
readwritenonatomicassign

Indicates that the time between data samples from the sensor has exceeded the rollover time (64 seconds).
