用BluetoothAdapter类，你能够在Android设备上查找周边的蓝牙设备然后配对(绑定)，蓝牙通讯是基于唯一地址MAC来相互 传输的，考虑到安全问题Bluetooth通讯时需要先配对。然后开始相互连接，连接后设备将会共享同一个RFCOMM通道以便相互传输数据，目前这些实 现在Android 2.0或更高版本SDK上实现。-With BluetoothAdapter class, you can find surrounding Bluetooth devices on the Android device then pairing (binding), Bluetooth communication is based on the unique address MAC to mutual transmission of pairing Bluetooth communications that take into account security issues. And then begin to connect with each other, connected devices will be shared the same RFCOMM channels to transmit data to each other, these implementations on Android 2.0 or higher version of the SDK.
