Figure 8 LED Location
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.
