A Python 3 library for driving the Itead RPI SIM800 GSM/GPRS Add-On V2.0 with the Raspberry Pi.

If you are using a Raspberry Pi Model 1 A+/B+, Model 2/3 B or Zero then this add-on board will connect directly to the 40-pin GPIO. If you are using an Model 1 A/B with a 28-pin GPIO connector then you will have to connect the board to the Pi with ribbon cable or dupont connectors as the composite video and audio connectors are in the way. Only the follow seven pins need to be connected:

This library has been tested with Python 3.4.2 running on a Raspberry Pi Model B (Rev.2) with Raspbian Jessie Lite (2016-05-27). It depends on PySerial and Ben Croston's RPi.GPIO which can be installed (if not already) as follows:

$ sudo apt-get update
$ sudo apt-get install python3-rpi.gpio
$ sudo pip3 install pyserial

The file sms.py is both the library and a working example if read/executed:

$ sudo python3 sms.py

Most methods also contain (brief) comments as to there function.

This setup has been tested in the UK using a SIM card from giffgaff with whom we have no relationship, personal or otherwise.
