Android开发——蓝牙配对自动设置PIN

注册广播

针对指定广播形式，对指定的广播做捕获操作。

  <!-- 增加一个配对码广播监听 -->
        <receiver android:name="com.winstar.minid.bletest.BluetoothReceiver">
            <intent-filter >
                <!-- 捕捉配对请求 -->
                <action android:name="android.bluetooth.device.action.PAIRING_REQUEST"/>
            </intent-filter>
            
        </receiver>
