While the Tile has no GPS fix, the red LED will blink with a 50% duty cycle (100ms on,
100ms off). If a GPS fix is acquired and then lost, the red LED will blink with a 2% duty
cycle (100ms on, 4900ms off) after the green LED. While the Tile has a valid GPS fix,
the red LED will not blink at all.
Green During the bootup sequence or shutdown, the green LED will be on. Afterwards, the
green LED will blink with a 2% duty cycle (100ms on, 4900ms off) while the Tile is
powered on
