AAD accelerometer features message

Automatic activity detection accelerometer features messages store the accelerometer statistics the device uses to detect activities automatically.

Fields

timestampDateTime
Moment the message refers to, in UTC. FIT stores it as seconds since the FIT epoch (December 31, 1989, 00:00:00 UTC); decoders usually expose it as a regular date.
timeUint16s
Length of the interval.
energyTotalUint32
Total accelerometer energy over the interval.
zeroCrossCntUint16
Number of zero crossings over the interval.
instanceUint8
Instance of the zero crossing algorithm.
timeAboveThresholdFloat64s
Time the accelerometer energy was above the threshold.
mesgNumString
Global message number identifying the kind of message. Decoders use it to know which profile to apply to the data.
