This is the data sent by a device to the Tracking API. The data must be accompanied by a valid access token to both authenticate the device and authorize the data storage.
Telemetry can contain GPS position, WLAN, Bluetooth or cell measurements along with a
payload of sensor measurements and a
timestamp specifying the time at which these measurements were taken. The received telemetry is evaluated against the associated geofences, rules and sensor rules. Events produced as a result of the rules evaluations will be recorded in the Tracking backend.
