iOS设备和放大器;蓝牙 [英] iOS Device & Bluetooth

问题描述

有谁知道外部蓝牙设备和iPhone / iPad的（4S起）。

Does anyone know the maximum data transfer rate between an external Bluetooth device and an iPhone / iPad (4S onwards).

我看了，在BT3.0 enchanced数据分别为24Mbs - 可以在iPhone支持这种

I read that enchanced data rates in BT3.0 were 24Mbs - can the iPhone support this?

什么是采用BT4.0 LTE可能的最大数据？

What is the maximum data possible using BT4.0 LTE?

谢谢你们！

推荐答案

iPhone / iPad的蓝牙4.0
数据速率取决于所涉及的设备的版本。
通常传统蓝牙数据速率是2.0或3.0 Mbps的理论通过空中比特率。将将转化为1.5-2.0左右Mbps的应用程序级的吞吐量。你可以期待在iPhone / iPad的（取决于你使用的配置文件和远程设备）

iPhone / iPad is Bluetooth 4.0 The data rate depends on the version of the devices involved. Typically Classic Bluetooth data rate is 2.0 or 3.0 Mbps theoretical over the air bit rate. Will will translate to around 1.5-2.0 Mbps application level throughput. You can expect this rate on the iPhone / iPad (depending on the profile you use and the remote device)

你所说的是BT 3.0 + HS（高速），24 Mbps的等是通过使用802.11作为蓝牙堆栈/轮廓底层MAC实现。
高速不支持在iPhone / iPad上。

What you have mentioned is for BT 3.0 + HS (High Speed) 24 Mbps etc is achieved by using the 802.11 as the underlying mac for Bluetooth stack / profiles. High Speed is not supported on the iPhone / iPad.

BT 4.0（在LE模式）主要用于需要非常低的功率，所以数据速率是不与LE的焦点（但一​​年的电池寿命）的应用最大数据速率是大约300 Kbps的传感器设备。 （当你有很高的数据要发送，则不应使用LE - 使用蓝牙经典代替），LE是对小间歇的数据传输进行了优化

BT 4.0 (in LE mode) is primarily for sensor devices that need very low power , so data rate is not the focus with LE (but battery life of year is) the application max data rate is around 300 Kbps. (You should not use LE when you have high data to send - use Bluetooth Classic instead), LE is optimized for small intermittent data transfers.
