SelfSyncEvent message
Event messages record everything that happens at a given moment of an activity: the timer starting and stopping, laps, alerts (heart rate, speed, power…), gear changes, rider position changes, radar threats, dive alerts and so on. The event and eventType fields tell what happened; the other fields hold the data specific to that kind of event.
Fields
