本文记录了一个Android应用与2.0蓝牙模块连接的步骤，包括注册广播接收蓝牙状态，获取并初始化BluetoothAdapter，搜索蓝牙设备，进行配对以及最终建立连接。

因项目需要，做一个与2.0蓝牙模块连接的Demo，在此记录一下

1.先注册个广播，来接收一下蓝牙的状态

MyBroadCastRevciver broadcastReceiver = null;
public void registerBroadcast(){
    broadcastReceiver = new MyBroadCastRevciver();
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(BluetoothDevice.ACTION_FOUND);
    intentFilter.addAction(BluetoothDevice.ACTION_BOND_STATE_CHANGED);
    intentFilter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
    intentFilter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
    registerReceiver(broadcastReceiver, intentFilter);
}


private String mac;
class MyBroadCastRevciver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            switch (intent.getAction()) {
                case BluetoothDevice.ACTION_FOUND:
                    Log.d("TAG", "找到蓝牙");
                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE
