单片机控制GSM模块实现短信收发。系统采用西门子解析模块tc35i与单片机通信，以AT指令控制TC35模块，涉及TEXT和PDU发送模式-GSM single-chip control module messaging. System analysis module tc35i with Siemens chip communication to the AT command control TC35 module, involving sending TEXT and PDU mode

这是一个通过PC机发指令到串口,单片机接收后通过发射模块,发送到玩具上,玩具解析,得得相应动作,通过调试成功,可以直接使用-This is a PC-issued instructions through the serial port, single-chip receiver module through the launch, sent to the toys, toys resolution, a corresponding action, through the debugging s

单片机控制GSM模块实现短信收发。系统采用西门子解析模块TC35I与单片机通信，以AT指令控制TC35模块。-GSM single-chip control module to send and receive text messages. Siemens Analytical system with single-chip communication module TC35I to AT commands control the TC35 module.

AT 指令通过GSM 串口发送到模块并接收返回指令。GPS 的控制指令也是 通过GSM 串口控制，GPS 串口只负责输出相应的GPS 信息.本文档时针对SIM908的AT指令集做解析。-Serial port to send AT commands to the module via the GSM and receive return instructions. GPS control command is serial control via GSM, GPS serial output
