4. Upload the coding into your Arduino Uno.
5. When done uploading the code, power ON your SIM808 and then press the start button.
6. Open up your serial monitor in Arduino IDE and set it to 9600 baud.
7. It takes a few minutes to get the coordinates but it should output like in the picture below.
Conclusion:
SIM808 GSM GPRS GPS Dev Board IPX SMA with GPS Antenna, can connect using GSM
to mobile service provider to send/receive SMS message and also GPRS GPS function that can
be locate to it exact coordinate receiving signal using GPS/BD antenna from satellite.
Furthermore, SIM808 can also be connected via Bluetooth to any device that support it to relay
any data/information from SIM808 to a third party device for example like a smartphone. To
test all this feature is pretty simple just by using the examples from SIM808 library installed in
Arduino IDE to test each features separately.
