对蓝牙系统核心协议栈的研究和实现

The research and realization of kernel protocols stack for Bluetooth

蓝牙是用于短距离内无线数字设备之间进行数据通信的一组协议的集合。包括基带协议、链路管理协议、逻辑链路控制和适应协议以及设备发现协议 ,组成了蓝牙系统的核心协议栈。作者提出一种客户 /服务器模型 ,并对客户端和服务端之间的信道连接进行了详细的讨论 ,包括客户端发起连接请求时的物理信道建立、服务端对连接请求的确认以及逻辑数据信道的建立等。最后 。

Bluetooth is an aggregate of protocols used to digital communication between wireless digital services in short distance. In the Bluetooth system, the core protocols stack are composed of BaseBand, Link ManagementProtocol, Logical and Link Controller Adaption Protocol and Service Discover Protocol. In the paper, a model composed of client and server will be brought forward and discussed in details. The discussion includes connection requesting from client, the establishment of wireless physical channel, the affirm of server to client's request and the establishment of logical data channel etc. Finaly, this paper gives the characteristic of the model.
