Each Bluetooth service on a machine needs a unique identifier, so I decided to give this service the UUID (Universal unique identifier) of 8841 (it could be any four-digit number you choose).
机器上的每台蓝牙设备都需要惟一的标识符，所以我决定将这个服务的UUID(统一惟一标识符)定为8841(可以是任意四位数字)。
Service Discovery Protocol (SDP) is one core protocol of bluetooth protocol stack, an important part of bluetooth system and the base of all user mode.
服务发现协议（SDP）是蓝牙协议体系中的核心协议之一，是蓝牙系统的重要组成部分之一，是所有用户模式的基础。
The Bluetooth SDP(Service Discovery Protocol) according to SIG specification, is designed for motion enviroment, and has no definition of carrying out service calling.
SIG规范中的蓝牙服务发现协议是针对运动环境的，对服务调用的实现也未做出规定。
In the Bluetooth system, the core protocols stack are composed of BaseBand, Link ManagementProtocol, Logical and Link Controller Adaption protocol and Service Discover protocol.
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。
