摘要
为了克服用手机发送短信时键盘空间的限制、设计了基于MG801A无线收发模块的短信收发系统。该系统由硬件系统和软件系统两部分组成。硬件系统主要由MG801A收发模块及其外围电路组成收发终端,并通过RS232串口与PC机连接:软件部分主要由单片机向模块发送AT(Attention)指令,从而使系统完成短信收发功能。
To overcome the limitation of the small keyboard in a mobile phone, a short messages receiving / sending system was designed, which based on the MG801A module, The system includes hardware system and software system, The MG801A module and its peripheral circuit constitute the rece[ving/sending terminal, and it links with computer by RS232, As software, the application program was designed, and it sends AT(Attention) command to module through Single-chip Microcomputer ,
