Overview

SIM800 GSM GPRS Add-on V2.0 Message Module Expansion Board for Raspberry Pi

Raspberry PI GSM Add-on V2.0 is customized for Raspberry Pi interface based on SIM800 quad-band GSM/GPRS/BT module. AT commands can be sent via the serial port on Raspberry Pi, thus functions such as dialing and answering calls, sending and receiving messages and surfing on line can be realized. Moreover, the module supports powering-on and resetting via software.

Features

PWR (Power): When there is normal supply to the board, the indicator keeps on.
8STATUS (SIM800 status): When SIM800 works normally, the indicator keeps on.

NET (SIM800 network status): used to indicate network status, the working status of the indicator is as below:

OFF SIM800 does not work
64ms on/800ms off SIM800 does not find network
64ms on/3000ms off SIM800 registers the network
64ms on/300ms off GPRS communicates

Specifications

Quad-Band 850/ 900/ 1800/ 1900 MHz
GPRS multislot class 12
Operation temperature: -40°C to +85 °C
Operation Level: Digital 3.3V DC
Interface: UART
Baud rate: 9600(default)

References

Install the RPI GSM ADD-on V2.3 on the Raspi 3B (Ensure Antenna attached before power up!)
Power Pi and boot up the Pi (assuming you have a SDcard in the Pi)
Open a terminal/console/shell command line

Run these commands:
wget https://www.waveshare.com/w/upload/3/3e/SIM800C-GSM-GPRS-HAT-Demo-Code.zip
mkdir temp
cd temp
unzip /home/pi/SIM800C-GSM-GPRS-HAT-Demo-Code.zip
sudo nano /etc/rc.local

# Add this line just before "exit 0" which will be on the very last line
