How to use
1. Connect the UART GPS NEO-6M module to a serial module. FT232 is applied as
the serial module in this document.
The connection between the GPS module and the serial module is listed as the
table below.

* PPS should be connected to the clock pulse output (CPOUT) of a MCU. However, this pin is
unconnected, in the case that the GPS module is connected to a computer.
2. Connect the serial module to the computer.
3. Start the serial debugging assistant, and set the serial port as below:
Select the corresponding serial port in the PortNo option. In this example,
COM8 is selected.
Baud rate: 9600(default).
8 data bits, 1 stop bit, no parity and no flow control.
4. After finishing the settings, you can see the serial debugging assistant will show
many data in its window, as the figure shows below.
The data shown in the figure above means that the connection is established
successfully, but it is unable to perform positioning.
In this case, please place the GPS module to the balcony or near the window, or
outdoors for testing, because GPS is less stable in searching signal indoors.
1. After waiting for a while, if the serial debugging assistant lists similar data in its
window as the figure shows below, it means GPS has performed positioning. And
you can see that the LED on the module, which remains on when GPS is unable
to perform the positioning, is flickering now.
