iOS设备和蓝牙 [英] iOS Device & Bluetooth

问题描述

是否有人知道外部蓝牙设备与iPhone/iPad(4S及更高版本)之间的最大数据传输速率.

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

我了解到BT3.0中的增强数据传输率为24Mbs-iPhone可以支持吗?

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

使用BT4.0 LTE可能获得的最大数据量是多少?

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

谢谢大家！

推荐答案

iPhone/iPad为蓝牙4.0 数据速率取决于所涉及设备的版本. 通常，经典蓝牙数据速率在空中比特率上理论值为2.0或3.0 Mbps.将转换为大约1.5-2.0 Mbps的应用程序级别吞吐量.您可以在iPhone/iPad上获得此价格(取决于您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)

您提到的BT 3.0 + HS(高速)24 Mbps等是通过使用802.11作为Bluetooth堆栈/配置文件的基础mac来实现的. iPhone/iPad不支持高速.

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(处于LE模式)主要用于需要非常低功耗的传感器设备，因此数据速率并不是LE的重点(但电池寿命是一年)，应用程序的最大数据速率约为300 Kbps. (当您要发送大量数据时，您不应该使用LE-而是使用Bluetooth Classic)，LE已针对小型间歇性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.
