Python实现的短信发送/接收库，支持多种型号的短信猫。主要功能有：

发送短信、检测信号强度

基于回调的来电和短信处理方法

支持短信状态报告追踪

使用Python异常包裹AT命令错误

模块化代码，具有良好的扩展能力

提供了一些简单的调试工具。

示例

短信接收和回复

#!/usr/bin/env python
Demo: handle incoming SMS messages by replying to them
Simple demo app that listens for incoming SMS messages, displays the sender's number
and the messages, then replies to the SMS by saying "thank you"
"""

from __future__ import print_function

import logging

PORT = '/dev/ttyUSB2'
BAUDRATE = 115200
PIN = None # SIM card PIN (if any)

from gsmmodem.modem import GsmModem

def handleSms(sms):
    print(u'== SMS message received ==\nFrom: {0}\nTime: {1}\nMessage:\n{2}\n'.format(sms.number, sms.time, sms.text))
    print('Replying to SMS...')
    sms.reply(u'SMS received: "{0}{1}"'.format(sms.text[:20], '...' if len(sms.text) > 20 else ''))
    print('SMS sent.\n')
    
def main():
    print('Initializing modem...')
    # Uncomment the following line to see what the modem is doing:
    logging.basicConfig(format='%(levelname)s: %(message)s', level=logging.DEBUG)
    modem = GsmModem(PORT, BAUDRATE, smsReceivedCallbackFunc=handleSms)
    modem.smsTextMode = False 
    modem.connect(PIN)
    print('Waiting for SMS message...')    
    try:    
        modem.rxThread.join(2**31) # Specify a (huge) timeout so that it essentially blocks indefinitely, but still receives CTRL+C interrupt signal
    finally:
        modem.close();

if __name__ == '__main__':
    main()
