Gammu
An USB Huawei Dcom or GSM module 800l

Hardware

Python 2.7 code to interface a cheap 2G SIM800L to a cheap Raspberry Pi 3

Connections

Hook up the SIM800 to the Pi Zero with a few wires:

SIM800 Pin	Pi Zero Pin
5V	Pin 2 - 5V
GND	Pin 6 - GND
VDD	Pin 4 - 5V
TX	Pin 10 - GPIO15 - RX
RX	Pin 8 - GPIO14 - TX
GND	Pin 14 - GND
RST	Pin -
-	-

Insert your SIM card into the SIM800

Install Gammu (python-gammu and gammu-smsd can be skipped - depending on requirements)

Check python is installed on your computer

python --version
python3 --version

Use command

sudo apt-get update & apt-get upgrade 

sudo apt-get install gammu
sudo apt-get install python-gammu
sudo apt-get install gammu-smsd
sudo apt-get install libgammu-dev

Find port USB device connected to

Connect your DCOM to your Raspberry Pi then:

dmesg | grep tty

[7.578478] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB0
[7.697942] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB1

Config gammu

gammu-config

set port /dev/ttyUSB0

sudo gammu-config

set port /dev/ttyUSB0

Check connected

sudo gammu --identify

Device : /dev/ttyUSB0
Manufacturer : Huawei
Model : E220 (E220)
Firmware : 11.117.03.01.156
IMEI : 3XX19301XXXXXX3
