19 CODEC Coder DECoder 编解码器 A device that converts analog to digital, and digital to analog for transmission over a digital communications system.
20 COF Ciphering Offset 加密补偿 component An architecture element denoting an identifiable set of software that performs a well-defined purpose.
181 connect to service connect to service The establishment of a connection to a service. If not already done, this includes establishment of a physical link, link and channel as well.
182 connectable devices connectable devices 可连接设备 Any device within range that will respond to paging from an initiator device. 在允许范围内的蓝牙设备，可以响应寻呼信息，并且建立连接。
183 connectable mode connectable mode A device that responds to paging (an attempt to establish a communication link) is said to be in connectable mode. The opposite of connectable mode is non-connectable mode. Connected device A device that is currently connected to the (LocDev. Connection A connection between two peer applications or higher layer protocols mapped onto a channel. Connectionless packet A packet of data is broadcast over the network without targeting a specific recipient to receive the packet. Connecting A phase in the communication between devices when a connection between them is being established. (Connecting phase follows after the link establishment phase is completed.) connectivity A domain of interconnected components that adhere to a defined set of connection rules. The set of rules is termed Connectivity Architecture. Connector An architectural element denoting a path for control or information flow between components.
184 CP Call Processing
185 CP Capability Provider 能力提供者 "A Capability Provider is a module within the local device that provides a service to other modules. Protocol stack modules (RFCOMM, L2CAP) are Capability Providers. So are ""application interface modules"" such as OBEX and ESC-AT. In fact, any module that registers a port that other modules can connect to is a Capability Provider." 本地设备的一个模块可以提供服务给其他模块，协议栈模块(RFCOMM, L2CAP)就是个能力提供者。诸如OBEX 和ESC-AT中的应用接口模块（application interface modules）也是个能力提供者。事实上，任何模块只要注册了一个端口，只要以让其他模块连接上去，那么该模块就是个能力提供者。
186 CPU Central Processor Unit The main processing component in a hardware device.
21 CRC Cyclic Redundancy Check 循环冗余校验 这是个添加到数据包中的16位码，用来判断payload数据传送得是否正确，带有CRC数据的payloads仅能由DM, DH 或者DV 包来携带。该CRC码由CRC-CCITT多项式生成，0x11021 (hex)。
187 CTC Computer Test Commands 公用交换电话网，即普通的电话网
188 CTP Cordless Telephone Profile 无绳电话应用
22 CVSDM Continuous Variable Slope Delta Modulation 连续可变斜率增量调制
23 DAC Device Access Code 设备访问码 用于寻呼状态、寻呼扫描和寻呼响应子状态，其代码来自于设备的蓝牙设备地址（BD_ADDR）。
366 DC Bias Direct Current Bias 直流补偿
24 DCE Data Communication Equipment 数据通信设备
25 DCE Data Circuit-Terminating Equipment 数据电路端连接设备 In serial communications, DCE refers to a device between the communication endpoints whose sole task is to facilitate the communications process; typically a modem
26 DCI Default Check Initialization 缺省的检查初始值 在蓝牙技术中，DCI定义为0x00 (16进制)。
269 DCID Destination Channel Identifier 目的信道标识 对于 L2CAP传送来说，是作为设备的本地终点使用的。它代表接收消息的设备的信道终点。它仅仅是个设备的本地名。参见SCID。
190 DD API Device Driver API
270 destination destination 目标蓝牙设备 用来接收另外一个蓝牙设备的动作。发送动作的设备称为源蓝牙设备（source）。目标蓝牙设备通常是已建立好的连接的一部分，但也有例外。（例如在inquiry / page 过程中）。
191 Device Discovery Device Discovery 设备发现 The mechanism to request and receive the Bluetooth address, clock, class of device, used page scan mode, and names of devices. 设备发现。一种请求和接收蓝牙地址，时钟，设备类别等的机制。
192 Device Layer Device Layer The group of protocols that handles the hardware in a Bluetooth device. The device layer handles components such as the display, keypad, and RF communications.
