Make sure you also have Both NL & CR for the serial command sender option. This
means when you send data to the Arduino via the console, it will put a newline/return
at the end.
Using the Test Sketch
The test sketch has a menu interface so you can test out just about everything the
FONA can do. The menu may change slightly as we add more functionality and
update code!
Continue onto the next few sections to see what functionality you can test with the
sketch
Hardware Test
Battery voltage
Lets begin by reading the battery voltage. That's the lipoly battery. This is handy if you
need to track when the battery is low! type b into the command window and hit Send
You'll see a print-out of the battery voltage in mV, so in this case its 3.726V
