摘　　要：主要研究蓝牙核心协议,采用主机-主控制器连接模型,利用单片机通过UART传输层控制蓝牙模块,在单片机中嵌入HCI协议,自动完成无线连接。利用AT89C2051单片机构成串行鼠标,将鼠标编码数据经蓝牙系统传输给计算机,实现无线鼠标功能。降低了成本,适用于更多的工业控制设备。在硬件的实现上,选用爱立信生产的蓝牙模块ROK101008,价位较低,性能可靠,蓝牙主芯片选用具有51内核的单片机,带有两个UART口的C8051F023,简化了电路,增加了整体电路的可靠性。The core protocol of Bluetooth was analyzed. With a host computer and host controller connection model, the Bluetooth module was controlled by a microcomputer through UART transport layer, thereby the HCI protocol was embedded in the microcomputer and the wireless connection could be automatically achieved. The series mouse was composed of an AT89C2051 microcomputer and the mouse codes were transferred to a computer by the Bluetooth system, thereby formed a wireless system. The Bluetooth module was Ericsson ROK101008 with low price and high reliability; the main Bluetooth chip was the C8051F023 who had 51 cores and two UART interfaces. The system is simple, cheap, and reliable.
