The green system LED can be controlled via the downlink command interface.
NOTE:
Any other LED pattern behaviour not described above most likely indicates a low battery.
For example, if steps 1-2 repeat continuously, the battery no longer has enough charge to power
the join procedure.

Reset Button Function
There is a reset button on the device, that can be pushed by a pin, such as a paper clip (see Figure
1-2). The button should not be pushed hard. The reset is instant, i.e. the button does not need to
be kept pushed. The reset restarts the microprocessor. All the FW load and configuration
parameters in the Flash are remembered during the reset.
NOTE
: Shutting down or resetting the Tracker will cause all unsaved user configurations to be
lost. Save your desired configuration to the Tracker flash before powering off or resetting the
Tracker.
3.5
Push Button Function
The Tracker has an externally accessible push button, actuated by pushing against the enclosure
on a designated area. The main objective of the push button is to trigger the Tracker to send an
uplink such that the Tracker (which acts as a Class-A LoRaWAN sensor) will open receive windows
to receive DL commands.
The definition of when a push button event is registered is user configurable. The default
configuration is pushing and releasing the button at least 3 times within 3 seconds. Alternatively,
the button can be configured to register an event by keeping the button pushed for a defined
number of seconds. In either case, when the event is registered, the Tracker sends an uplink. The
uplink can be empty or configured to contain the battery voltage, acceleration vector,
temperature, BLE scan results, or any combination of these.
