基于GSM模块实现短信发送

短信的发送需要GSM模块和处理器协作完成,GSM模块与ARM处理器通过串口连接,处理器向串口发送接收AT命令与GSM模块形成通信回路。中文短信的发送采用PDU模式,根据PDU模式标准形成PDU发送包,实现短信发送。本文根据无线电话项目的短信发送模块的实际开发流程编写,本文内容通过测试。

Design of Message Sending with GSM Module

Sending a message needs GSM module and processor to work together. GSM module and ARM processor are connected through the series. AT order set is the communication protocol between the module and controller. Processor receives and sends AT order through series and forms the loop with the GSM module, then realizes the message sending and receiving. Sending message uses PDU mode. This article introduces the flow of actual research on message sending module.
