1、 前言

蓝牙模块,是一种集成蓝牙功能的 PCBA 板,用于短距离无线通讯,按功能分为蓝牙数据模块和蓝牙语音模块。蓝牙模块是指集成蓝牙功能的芯片基本电路集合,用于无线网络通讯,大致可分为三大类型:数据传输模块远程控制模块等。一般模块具有半成品的属性,是在芯片的基础上进行过加工,以使后续应用更为简单。

2、 方案概述

Ameya360 蓝牙模块解决方案主要由无线射频模块(Radio):蓝牙最底层,带微带天线,负责数据接收和发送。基带模块(BaseBand):无线介质访问约定。提供同步面向连接的物理链路(SCO)和异步无连接物理链路(ACL),负责跳频和蓝牙数据及信息帧传输,并提供不同层次的纠错功能(FEC 和 CTC)。链路控制模块(LC):蓝牙数据包的编码和解码。链路管理模块(LM):负责创建、修改和发布逻辑链接,更新设备间物理链接参数,进行链路的安全和控制。主机控制器接口(HCI):是软硬件接口部分,由基带控制器、连接管理器、控制和事件寄存器等组成;软件接口提供了下层硬件的统一命令,解释上下层消息和数据的传递。硬件接口包含 UART、SPI 和 USB 等
