摘要
介绍了西门子的GSM无线通信模块TC35i,并提出了由TC35i模块通过搭建外围电路构成一个GSM Modem,PC机通过串口数据线向其发送AT指令,从而实现短消息的发送和接收。详细介绍了TC35i的外围电路设计,给出了实际的电路连接图,并介绍了通过PC机给TC35i写AT指令从而实现收发短消息的过程。
This paper introduces Siemens GSM communication module TC35i,and proposes a SMS GSM modem detailedly which constructed by TC35i and some perpheral circuits,and which communicates with personal computer through serial port. It also introduces the peripheric ciruit design of TC35i,the protel drawing,and the course of writing AT instruction to TC35i to implement receiving and sending messages through PC.
