Side operations

Whatever the operating mode (except OFF mode), the trackers support side operations as shown in the following table:

(1) All side operations can be accrued.

Periodic position message reporting​

The device sends additional positions at the periodic_pos_period frequency. This feature is disabled when its associated configuration parameter is set to 0.

This periodic position reporting uses the geoloc_method geolocation strategy.

Note
  1. If the selected geoloc_method uses GPS or LPGPS, the position is sent at the end of gps_timeout or agps_timeout delay (even if the acquisition is finished before)
  2. A periodic position cannot be interrupted by a regular acquisition (triggered by the operational mode).

Position on Demand​

The tracker position can be requested via LoRaWAN™ downlink message. In this case, the geoloc_method strategy is used.

Note

This action has precedence over the main operational mode. So, if a position acquisition is already in progress, the operation is stopped, and the demand is serviced.

Alert position​

Alert position can only be done with tracker having a button or a reed switch acting like a button.

After the button press(es) for the Alert position is done, (button action is configured in button_mapping parameter) the tracker automatically starts a position acquisition using the geoloc_method strategy. As previously stated, If the position acquisition is in progress, the operation is stopped, and the demand is serviced.

Between 2 button sequences, a delay of 60 seconds must be respected. If this delay is not respected the second sequence won't be considered.

The LoRaWAN™ position messages are tagged with the alert flag and the position on demand flag.

Periodic activity reporting​

The tracker can report periodically its activity (motion detection). The reporting frequency is controlled by the parameter periodic_activity_period. When this parameter is set to 0, this feature is disabled.

The associated LoRaWAN™ uplink message will contain the history of the activity split in six-time windows equals to 1/6 of the configured period (periodic_activity_period).

Note

motion_sensitivity parameter should have a value between 100 and 200.

Scan collection​

A scan collection is a WIFI or a BLE extra scan used to sense the environment around the tracker, which is done after the usual geolocation and reported via LoRaWAN™ just after the position.

Angle detection​

Angle detection is a side operation, that triggers an event when the tracker angular position reaches a configured critical angle between a reference gravity vector and the current measured vector.

This feature uses the on-board accelerometer, also used for motion detection.

BLE geozoning​

The BLE geozoning is a side operation, which periodically scans BLE beacons and reacts according to the type of beacons detected.

Note

If the BLE geozoning feature is activated and the collection_scan_type parameter is set to BLE, then the BLE collection message is not sent after a position. Only the BLE geozoning collection message is sent.

BLE Beaconing​

The purpose of this feature is to configure the tracker as a BLE beacon. The supported beaconing types are:
