iOS 设备 &蓝牙 [英] iOS Device & Bluetooth

问题描述

有谁知道外接蓝牙设备和 iPhone/iPad(4S 以上)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).

我读到 BT3.0 中增强的数据速率为 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 的最大数据量是多少?

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

谢谢各位！

推荐答案

iPhone/iPad 是蓝牙 4.0数据速率取决于所涉及设备的版本.典型的经典蓝牙数据速率是理论上的 2.0 或 3.0 Mbps 空中比特率.Will 将转化为大约 1.5-2.0 Mbps 的应用级吞吐量.您可以在 iPhone/iPad 上获得此费率(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 作为蓝牙堆栈/配置文件的底层 mac 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(在 LE 模式下)主要用于需要非常低功耗的传感器设备，因此数据速率不是 LE 的重点(但一年的电池寿命是)，应用程序的最大数据速率约为 300 Kbps.(当您有大量数据要发送时，不应使用 LE - 请改用蓝牙经典)，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.
