Caution
The platforms mentioned above as supported is/are an indication of the
module's software or theoritical compatibility. We only provide software
library or code examples for Arduino platform in most cases. It is not
possible to provide software library / demo code for all possible MCU
platforms. Hence, users have to write their own software library.

Play With Arduino
This sample simply reads from the GPS by using software serial
and sends it back on the serial port.
Hardware
Step 1. Prepare the below stuffs:
Seeeduino V4.2 Base Shield

V4.2-p-2517.html]
Get One Now
[https://www.seeedstudio.com/Base
Shield-V2-p-1378.html]
Step 2. Connect Grove - GPS to port D2 of Grove-Base Shield.
Step 3. Plug Grove - Base Shield into Seeeduino.
Note
If this is the rst time you work with Arduino, we rmly recommend you to
see Getting Started with Arduino
[https://wiki.seeedstudio.com/Getting_Started_with_Arduino/] before the
start.

Software
Step 1. Install u-center [https://www.u-blox.com/en/product/u-
center-windows] software.
Step 2. Copy the code into Arduino IDE and upload. If you do
not know how to upload the code, please check how to upload
code [https://wiki.seeedstudio.com/Upload_Code/].
Note
Please note that the u-center software is for windows only.

Step 3. Open U-center.
Step 4. Click Receiver -> Port and select the COM port that the
Arduino is using.
Step 5. Click Receiver -> Baudrate and make sure 9600 is
selected.
Step 6. Click View -> Text Console and you should get a window
that will stream NMEA data.
Step 7. Open the serial monitor,You can see as show below:

31 for (int i=0; i<count;i++)
32 {
33 buffer[i]=NULL;

We also can view data in Google Earth:
Step 1. Click File -> Database Export -> Google Earth KML
Step 2. This should launch Google Earth with the history that
was captured by u-center.
Step 3. Alternatively, data can be recorded by pressing the red
circle on the toolbar which will then ask where you want to save
the record.
Step 4. When we have captured enough data, click the black
square to stop recording.
Step 5. We can then convert the .ubx le generated to KML by
using uploading the ubx le to GPSVisualizer
[http://www.gpsvisualizer.com/], and the location (Red spot)
would be shown on the map as following:

Attention
Tests would rather be taken outdoors to avoid location inaccuracy caused
by bad signal transmission.
