If your GPS is indoors, you will see the following NON-
fully populated messages. However, they should have
the correct format and the checksum (*XX) at the end.

If the baud rate is incorrect you will NOT see the NMEA
messages but instead the following.
If the GPS baud rate is not close to your SF baud rate
setting, you may not even see this message.
