sim-modem

Easy library for interfacing with mobile modems. Tested with Simcom SIM7600G-H on Raspberry PI Zero W. The commands could be different for other modems.

Installation

pip install sim-modem

Usage

from sim_modem import Modem

modem = Modem('/dev/ttyUSB2')

signal_quality = modem.get_signal_quality()
print(signal_quality)

modem.send_sms('[phone]', 'Hello World!')

API

Modem (Class)

Main class for interfacing with the modem. Each method raise an exception if the modem returns an error. If the command is successful, the function returns the response from the modem.

Modem(        
    address, # Address of the device tty (e.g. "/dev/ttyUSB2")
    baudrate=460800, # Baudrate of the device. Default: 460800
    timeout=5, # Timeout for the serial connection. Default: 5
    at_cmd_delay=0.1, # Delay between AT commands. Default: 0.1
    debug=False # Log commands and responses from modem, test command support before executing them. Default: False
)
