Telemetry

This is the data sent by the device to HERE Tracking. The data must be accompanied by a valid access token to both authenticate and authorize data storage.

Telemetry can contain GPS position, WiFi, Bluetooth or cell measurements along with a payload of sensor measurements and a timestamp specifying the time at which these measurements were taken.

Telemetry recorded in the past can be uploaded to enable recording of offline sensor readings and positions. If historical telemetry is uploaded, it is compared against associated geofences and transitions are recorded but notifications are not generated as they may be significantly out-of-date.
