Operation, Alarms, and Management
3.1
Configuration
The Tracker supports a full range of OTA configuration options.
Specific technical details are
available in the Tracker TRM [1]. All configuration commands need to be sent OTA during a
Tracker’s DL windows.
3.2
Default Configuration
By default, the Tracker is configured to:
•
Report the battery voltage once per day,
•
Report an empty UL when the push button is pressed 3 times in less than 3 seconds,
•
Report the acceleration vector every time motion is detected, and
•
Scan and report up to 4 discovered BLE devices with the largest RSSIs once every hour.
3.3
LED Behaviour
See Figure 1-2 for the location and identification of the Tracker LEDs. The boot and join LED
procedure is as follows.
1.
Both LEDs will come on briefly when power is first applied.
2.
After a small delay (
< 1
s) the LEDs will turn off and one of them will blink briefly.
a.
If the green system LED blinks, then all health checks on the board passed.
b.
If the red LoRa LED blinks, then one of the health checks failed. Consider replacing
the battery, or moving the sensor to an environment within temperature range.
3.
Immediately after the boot pattern, the join procedure will begin. During this time the
green system LED will blink continuously until the sensor has joined a network.
4.
The red LoRa LED will now blink whenever LoRa activity occurs on the sensor (transmitting
or receiving packets, including the join request packets).
During normal operation,
•
The red LoRa LED will blink whenever LoRa activity occurs on the sensor (transmitting or
receiving packets), and
