python-gsmmodem-new

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.

FAQ

List all modem ports

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

> ls /dev/ttyUSB*

Device or resource busy error

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 .
