When you upload this code you'll have to wait ~29s to get a lock onto any satellites. After that first lock, the backup
battery on the board will provide power to some internal systems that will allow for a
hot start
the next time you
turn on the board. The
hot start
only lasts four hours, but allows you to get a lock within one second. After you get
a lock the serial terminal will start listing longitude and latitude coordinates, as seen below. Make sure to set the
serial monitor to
115200 baud
.
