蓝牙4.0与旧蓝牙 [英] Bluetooth 4.0 with older Bluetooth

问题描述

我试图实现使用蓝牙4.0模块的应用程序，我不知道，如果使用该应用程序与iPhone 3GS包含一个简单的蓝牙2.1 + EDR模块，将会使我充分利用低能量的在我的4.0模块。
谢谢你的答案

i'm trying to implement an application using a Bluetooth 4.0 module, and I wonder if using this application with an Iphone 3GS containing a simple Bluetooth 2.1 EDR module is going to enable me take advantage of the the low energy in my 4.0 module. Thank you for your answers

推荐答案

蓝牙4.0标准，其中既包括传统的蓝牙基本速率/增强型数据速率（BR / EDR）和蓝牙低功耗（BLE或蓝牙智能，这是一个营销的名称）。

Bluetooth 4.0 is the standard, which includes both classical Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and Bluetooth Low Energy (BLE, or Bluetooth Smart, which is a marketing name).

兼容性取决于设备和蓝牙芯片例如在它是一个BR / EDR只有芯片（蓝牙3.0），一个只BLE芯片或双模芯片既能BR / EDR和BLE的。双模式芯片可以（至4.1，至少）只在任BR / EDR或BLE模式操作为任何给定的连接。

Compatibility depends on the the device and Bluetooth chip e.g. is it a BR/EDR only chip (Bluetooth 3.0), a BLE only chip or a dual-mode chip capable of both BR/EDR and BLE. A dual-mode chip can (until 4.1, at least) only operates in either BR/EDR or BLE mode for any given connection.

一个双模式芯片，认证为蓝牙4.0，可以而且应该能够连接到蓝牙2.1芯片，BR / EDR模式。

A dual mode chip, certified as Bluetooth 4.0, can and should be able to connect to a Bluetooth 2.1 chip, in BR/EDR mode.

一个蓝牙BLE（Bluetooth Smart功能）芯片将无法

A Bluetooth BLE (Bluetooth Smart) chip will not be able to.

首先，你必须清楚地确定你的蓝牙4.0模块只能够BLE的。

First, you must clearly determine if your Bluetooth 4.0 module is only capable of BLE.
