Checking the Working Status of the Module

To check the working status of the module, first check to see the NMEA sentence
output through TX using various application tools. For example, you may use the
Windows tool HyperTerminal, or you may use another GNSS application program.
Secondly, if there is no NMEA output at the TX pin, this indicates that the module is
currently not working. Please double check your schematic design. The following is a
list of possible items to check:
Item 1: VCC
The voltage should be kept between 1.71V to 1.89 V (typical: 1.8 V).
Item 2: TX0
The TX0 pin of the module outputs normal GNSS NMEA information.
