应用领域：智能家电

方案类型：成品

主控芯片：rtl8761

方案概述

主要应用智能家电进行ble及a2dp音频数据传输，及蓝牙pos机数据传，在用户需要控制蓝牙设备及家电时可以通过手机APP进行控制pos及家电。蓝牙接收器主要实现接收手机APP下发的数据及对设备进行指命令控制。

蓝牙接收器是指能接受传输方式为蓝牙的接收器，一般支撑PC与Mac，现今已经广泛运用于生活中，如我们常用的蓝牙耳机、蓝牙音箱、蓝牙鼠标、蓝牙键盘等都属于蓝牙接收器。

蓝牙适配器一般用在电脑上,用来连接蓝牙设备，具有蓝牙信号的接收和发送功能,可以算是蓝牙接收器的一种;就像网络适配器用来连接网络设备一样;你上面说的蓝牙接收器属于专用设备，一般配套其他设备使用，像GPS蓝牙接收器，可以连在手机使用GPS功能，不同的蓝牙接收器有不同的价钱。

RTL8761ATV

Bluetooth 2.1/3.0/4.0 Controller, UART Interface

General Description

The Realtek RTL8761ATV-CG is a highly integrated single-chip Bluetooth 2.1/3.0/4.0 controller with a UART interface. It combines a BT Protocol Stack (LM, LL, and LE), BT Baseband, modem, and BT RF in a single chip.

The RTL8761ATV Bluetooth controller is compatible with Bluetooth core specification v4.0, and supports dual mode (BR/EDR + AMP + Low Energy Controllers). It is compatible with previous versions, including v2.1 + EDR and v3.0 + HS. For BR/EDR, it supports scatternet topology and allows active links in slave mode and master mode. For Low Energy, it supports multiple states and allows active links in master mode. The links in BR/EDR and LE can be active simultaneously.
