This part describes available callbacks that you can use to subscribe to certain events that can be necessary for your project

Events

  • Location update
  • Tracking started
  • Tracking stopped
  • Speed threshold violation
  • New events
  • Deprecated events (High-frequency events)
  • Collision (High-frequency events)

Setting up

High-frequency events

In iOS/Android, you can directly receive data about recorded events in a single format with the server.
The description of the classes is contained in the public class DTEventPoint on iOS, and Android in data class Event
