如何使用蓝牙4.0（BLE）如何使A2DP蓝牙配置文件工作？ 我需要AptX编解码器吗？
[英]How are you able to get an A2DP bluetooth profile to work using bluetooth 4.0 (BLE)? Do I need an AptX codec?
问题描述
I've been reading that BLE only works with a small amount of profiles (based on GATT and other smaller use specific profiles), but I've seen many Bluetooth 4.0 headphones that use A2DP available on the market (examples below). 
我一直在阅读BLE仅适用于少量配置文件（基于GATT和其他较小用途的特定配置文件），但是我已经看到市场上有许多使用A2DP的蓝牙4.0耳机（以下示例）。 However, all of the bluetooth 4.0 headphones have one thing in common…use of the aptX codec. 但是，所有蓝牙4.0耳机的共同点都是……使用aptX编解码器。 What is aptX and is it way to get A2DP to work as a profile using bluetooth 4.0? aptX是什么？使用蓝牙4.0如何使A2DP用作配置文件？ Is there another way anyone knows about to pass audio and remote control commands to a mobile device over BLE? 有没有人知道通过BLE将音频和远程控制命令传递给移动设备的另一种方式？

BLE will not support A2DP. BLE将不支持A2DP。 from the specifications provided on the link, these devices are dual mode(supports both BT Classic and BT LE).APTx is a codec and provides better sound quality than SBC but SBC is mandatory to support in A2DP profile. 从链接上提供的规范来看，这些设备是双模式的（同时支持BT Classic和BT LE）。APTx是一种编解码器，比SBC提供更好的声音质量，但SBC必须在A2DP配置文件中支持。
