我目前正在开发一个应用程序，我需要扫描通过Bluetooth classic安装了我的应用程序的移动设备。我知道蓝牙LE的扫描方法接受 APPLICATION_UUID 。如果有人知道BT Classic的方法请分享，提前谢谢。

似乎BT Classic没有这样的方法，但你可以过滤＆＃34;扫描＆＃34;设备Device Class：

BroadcastReceiver mReceiver = new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();

            if(action.equals(BluetoothDevice.ACTION_FOUND)){
                BluetoothDevice btDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

                if(btDevice .getBluetoothClass().getDeviceClass() == BluetoothClass.Device.<your_class>) {
                    // do your magic with filtered device
                }
            }

您还可以检查多个设备类：

int deviceClass = btDevice .getBluetoothClass().getDeviceClass()

if (deviceClass == Device.AUDIO_VIDEO_WEARABLE_HEADSET
                        || deviceClass == Device.AUDIO_VIDEO_CAR_AUDIO
                        || deviceClass == Device.AUDIO_VIDEO_HANDSFREE
                        and so on.

Bluetooth Classic：仅扫描特定设备
