GSM modem module for Python

python-gsmmodem is a module that allows easy control of a GSM modem attached to the system. It also includes a couple of useful commandline utilities for interacting with a GSM modem.

Its features include:

• simple methods for sending SMS messages, checking signal level, etc
• easy-to-use API for starting and responding to USSD sessions and making voice calls
• handling incoming phone calls and received SMS messages via callback methods
• support for SMS PDU and text mode
• support for tracking SMS status reports
• wraps AT command errors into Python exceptions by default
• modular design; you easily issue your own AT commands to the modem (with error checking), or read/write directly from/to the modem if you prefer
• comprehensive test suite

Bundled utilities:

• GSMTerm: an easy-to-use serial terminal for communicating with an attached GSM modem. It features command completion, built-in help for many AT commands, history, context-aware prompt, etc.
• sendsms.py: a simple command line script to send SMS messages
• identify-modem.py: simple utility to identify attached modem. Can also be used to provide debug information used for development of python-gsmmodem.

There are multiple ways to install python-gsmmodem-stk package:

pip install python-gsmmodem-stk

pip will automatically download and install all dependencies, as required. You can also utilise easy_install in the same manner as using pip above.

If you are utilising python-gsmmodem-stk as part of another project, add it to your install_requires section of your setup.py file and upon your project's installation, it will be pulled in automatically.

Download a python-gsmmodem-stk archive from PyPI, extract it and install the package with command:

python setup.py install

Note that python-gsmmodem-stk package relies on pySerial for serial communications: https://github.com/pyserial/pyserial

Clone from GitHub:

git clone https://github.com/strokovnjaka/python-gsmmodem.git
cd python-gsmmodem/
python setup.py install

To run all unit tests, do:

python setup.py test

Unit test code coverage information may be generated by using coverage. You can execute it directly from setup.py by doing:

python setup.py coverage

This will run all unit tests and report on code coverage statistics.

This package contains Sphinx-based documentation. To manually build or test the documentation locally, do the following:

git clone https://github.com/strokovnjaka/python-gsmmodem.git
cd python-gsmmodem
pip install .[doc]
cd doc
make html

For true isolation, you may wish to run the above commands within a virtualenv, which will help you manage this development installation.

You can simply list all ttyUSB devices before and after pluging the modem in.

ls /dev/ttyUSB*

On Windows, port is from COM1 to COM9, you can check using the 'mode' command in cmd.

Check running processes. The device could be occupied by another program or another instance of gsmmodem which is still running in the background. Run sudo lsof | grep tty, try to locate the problematic process and sudo kill <PID>.
