SIM808 Shield Tests

Here you can find some simple tests for the SIM808 shield which is very popular for prototyping projects.

You need a special firmware to use Bluetooth function. I got the files from this websites:

• https://www.itead.cc/wiki/SIM808_GSM/GPRS/GPS_Module
• http://simcom.ee/documents/?dir=SIM808

Instructions for flashing could be found here.

Brand Name: DIYmall

Model Number: FZ1735

With the shield I got this link to get started with the product where you can find some manuals and basic tools.

GPRS Internet Connection

For internet configuration it was enough reading the SIM800 Series_TCPIP_Application Note_V1.02 document.

For configuring an APN which is using username and password it was useful to read this webpage.

Interface with Arduino

Regarding folder rescueRoutine.

Here we built a simple routine triggered by a button. GPS is constantly saving positions and upon button pressure the last position is sent via SMS to a phone number and the module starts to wait for a call.

This was implemented using the DFRobot_SIM808 library that I found here. Also used an Arduino UNO R3 and his hardware serial interface.
