Bluetooth Low Energy (BLE)

小米手环就是BLE4.0，在android手机上用HMBLEComAssistant.apk可以搜到小米手环。

update,2015-09-25 12:08:41用delphi的BLE例子搜到小米手环了！！

蓝牙GAP、GATT(Generic Attribute Profile)

蓝牙音箱，通过android、iPhone都可以搜索到。

小米蓝牙音箱和小米手环的蓝牙版本完全相同吗？

蓝牙耳机：蓝牙协议：HFP/A2DP/HSP/AVRCP

手环里使用了蓝牙4.0 BLE技术

Discovering Devices

BluetoothLE does not work as the Classic Bluetooth, you do not need to pair the devices. BluetoothLE clients need to discover BluetoothLE servers.

蓝牙版本 V4.0 BLE

一节钮扣电池在静态工作状态可以支持一年。

蓝牙低功耗，也就是早前的Wibree，是蓝牙4.0版本的一个子集，它有着全新的协议栈，可快速建立简单的链接。作为蓝牙1.0 – 3.0版本中蓝牙标准协议的替代方案，它主要面向对功耗需求极低、用纽扣电池供电的应用。芯片设计可有两种：双模、单模和增强的早期版本。早期的Wibree和蓝牙ULP（超低功耗）的名称被废除，取而代之的是后来用于一时的BLE。
