摘要
蓝牙是一种短距离小范围的无线数据与语音通信协议标准。本文先对蓝牙技术进行简要介绍,而后对蓝牙的协议体系结构及各个协议之间的关系进行说明,着重介绍了主机控制器接口(HCI)层及HCI指令和HCI事件的实现机制。最后以Ericsson公司的蓝牙模块ROK101008为例,详细分析了单片机与蓝牙模块的硬件接口和软件接口的实现过程,从两个方面来说明单片机如何控制蓝牙模块,为实现蓝牙模块在嵌入式系统中的应用做铺垫。
Bluetooth is a kind of protocol standard of data and voice wireless communication inshort distance and little range area.This paper give a brief introduction firstly about Bluetoothtechnology,then the protocols of Bluetooth and the relationship of them ,especially HCI layer andthe implementing mechanisms of HCI commands and HCI events .At last ,taking the Bluetooth ModuleROK101008 made in Ericsson Company for example,we analyse in detail the hardware interface and theimplementing process of software interface between MCU and Bluetooth Module for showing how MCUcontrol Bluetooth Module.It will pave the way for Bluetooth Module used in Embedded Systems.
