截止的Andr​​oid 4.3，与蓝牙低耗能支持Android设备只能充当一个中央设备。由于被赋予在的Andr​​oid 4.3蓝牙LE 文档：

Till Android 4.3, an Android device with Bluetooth Low Energy support could only act as a central device. As is given in the Android 4.3 Bluetooth LE docs:

的Andr​​oid 4.3（API等级18）引入了内置的蓝牙低能耗平台，支持在核心作用，然后提供的API，应用程序可以用它来发现设备，查询服务，和读/写特点。

Android 4.3 (API Level 18) introduces built-in platform support for Bluetooth Low Energy in the central role and provides APIs that apps can use to discover devices, query for services, and read/write characteristics.

通过引进的Andr​​oid 4.4奇巧，可它也表现为外围设备吗？我找不到任何文档。如果没有，那么我们不得不等待的Andr​​oid 4.5获取Android设备上的BTLE外设模式？或者有没有在Android设备可充当外围设备的任何替代办法？

With the introduction of Android 4.4 KitKat, can it also behave as a peripheral device now? I couldn't find any documentation of that. If not, then do we have to wait for Android 4.5 for getting the BTLE peripheral mode on Android device? Or is there any alternative way in which an Android device can be made to act as a peripheral device?

通过查看完整的API不同，总之答案：NO

By looking at the full api difference, the answer in short : NO

要添加外围支持角色，现在你必须让你的手脏定制的操作系统级别的Bluedroid堆栈，或者试试你的运气在XDA开发者，看是否有人已经这样做过。我不知道在硬件层面目前Android手机的支持外设的角色，虽然。

To add peripheral role support now you have to get your hands dirty to customize the Bluedroid stack in the OS level, or try your luck on XDA developers to see if anyone has done this before. I am not sure the current Android phone support peripheral role at hardware level,though .
