蓝牙核心框架 | bluetooth

Bluetooth core system architecture

蓝牙核心系统由一个 Host，一个Primary Controller 和0个或多个Secondary Controllers组成。

Link Manager, Link Controller and BR/EDR Radio blocks comprise a BR/EDR Controller.
An AMP PAL, AMP MAC, and AMP PHY comprise an AMP Controller.
Link Manager, Link Controller and LE Radio blocks comprise an LE Controller.
L2CAP, SDP and GAP blocks comprise a BR/EDR Host.
L2CAP, SMP, Attribute protocol, GAP and Generic Attribute Profile (GATT) blocks comprise an LE Host.
A BR/EDR/LE Host combines the set of blocks from each respective Host.

蓝牙核心协议有：
* Radio (PHY) protocol
* Link Control (LC) and Link Manager (LM) protocol or Link Layer (LL) protocol
* AMP PAL
* Logical Link Control and Adaptation protocol (L2CAP)
* AMP Manager Protocol

另外，Service Discovery Protocol (SDP)和Attribute Protocol (ATT)是应用层协议。

core architectural blocks

这里介绍核心体系结构的组成部分。

Host Architectural Blocks

BR/EDR and LE 体系有一部分是共用，有一部分是各自实现。

• Channel Manager
• L2CAP Resource Manager
• Security Manager Protocol
• Attribute Protocol
• AMP Manager Protocol
• Generic Attribute Profile
  GATT is used on LE devices for LE profile service discovery.
• Generic Access Profile

BR/EDR/LE Controller Architectural Blocks

BR/EDR and LE 体系有一部分是共用，有一部分是各自实现。

• Device Manager
• Link Manager
  Link Manager Protocol (LMP) in BR/EDR and the Link Layer Protocol (LL) in LE
• Baseband Resource Manager
• Link Controller
• PHY

AMP Controller architectural blocks

• AMP HCI
• AMP PAL
• AMP MAC
• AMP PHY
