Industrial Tracker Reference Guide FW 1.8 V0.2
4 FUNCTIONING
4.1 Main operatng modes
4.1.1
Overview
The tracker supports up to fve diferent operatonal modes: Standby, Moton tracking, Permanent
tracking, Start/End tracking, Actvity tracking.
The mode is confgurable using confguratons parameters
For more details, please refer to the folloting chapter:
Parameters for operatonal modes
Along to the main operatng mode, the tracker can perform extra operatons knotn as side
operatons.
Notes
1i The LoRa transmission periods may not be respected due to the duty cycle nettork
constraint.
2i Event messages can also be sent depending on the confguraton of bits 6, 8 and 9 of the
config_flags
parameter. (see table in secton
4.1.2
Standby mode
The tracker sends periodically short LoRa messages, called heartbeat, at the confgured frequency
(
lora_period
). The device positons can be obtained in this mode by using the side operatons
secton).
4.1.3
Moton traciing mode
The tracker provides positons at the
ul_period
frequency only then the device is moving. The
positons are given by the geolocaton strategy defned by
geoloc_sensor parameter
.
When the device is not moving, the positon message is replaced by the heartbeat message
transmited at the
lora_period
frequency.
The end of moton is detected then the device has not moved during a
motion_duration
delay.
4.1.4
Permanent traciing mode
The device reports its positons at the
ul_period
frequency regardless the moton. It uses the
geoloc_sensor
geolocaton technology.
Heartbeat messages are sent if there are no uplink message during
lora_period
seconds.
Note
Regular positons can also be obtained using standby mode + side operaton
periodic positon
.
to have an example of confguraton.
