关于Android的蓝牙发展的两个问题：

有没有一种方法，使蓝牙是始终打开（我会在我的应用程序很长的设备发现阶段）中的Andr​​oid？据我所看到的默认值是一个数，从120秒下降。

是否存在任何开源蓝牙API实现？

Two question on Bluetooth development on Android:

Is there a way to enable Bluetooth to be always on (I might have a long device discovery phase in my application) in Android? As far as I can see the default value is a count down from 120s.

Does it exist any open source Bluetooth API implementations?

Bluetooth implementation is now available in the Android 2.0 API. See this and this.
