During the boot and join procedure:
 Both LEDs will come on briefly when power is first applied.
 After a small delay (< 1 second) the LEDs will turn off and one of them will blink briefly.
o If the System (green) LED blinks, then all health checks on the board have passed.
o If the LoRa LED (red) blinks, then one of the health checks has failed. Consider
replacing the battery, or moving the sensor to an environment within the
temperature range.
 Immediately after the delay, the join procedure will begin. During the time the System
LED will blink continuously until the sensor joins a network.
 The LoRa LED will now blink whenever LoRa activity occurs on the sensor (transmitting or
receiving packets).
During normal operation:
 The LoRa LED will blink whenever LoRa activity occurs on the sensor (transmitting or
receiving packets)
 The System LED can be controlled via the downlink command interface.
