Android 上的蓝牙 - 如何连接到正确的蓝牙设备？

我正在编写一个通过 rfcomm 与外部附件通信的程序。我的问题是我不知道识别我的设备的正确方法是什么。我现在这样做的方式是这样的：

Set<BluetoothDevice> pairedDevices = mBluetoothAdapter
                .getBondedDevices();
        for (BluetoothDevice device : pairedDevices) {
            if (device.getName().equals(MY_DEVICE_NAME)) {
                this.myDevice = device;
                break;
            }
        }

然而，这种方法依赖于设备的名称，这对我来说似乎又脏又糟糕:) 有更好的方法吗？我尝试查看 BluetoothDevice 但似乎没有任何帮助 - 这个名字真的是最好的方法吗？我看到在某些地方人们说我应该使用 UUID，但它用于在我拥有设备后打开设备的套接字：

            _socket = myDevice.createRfcommSocketToServiceRecord(MY_UUID);

有更好的方法吗？

I'm writing a program that speaks with an external accessory over rfcomm.
My problem is that I don't know what the correct way of identifying my device is.
the way I do it now is like this:

Set<BluetoothDevice> pairedDevices = mBluetoothAdapter
                .getBondedDevices();
        for (BluetoothDevice device : pairedDevices) {
            if (device.getName().equals(MY_DEVICE_NAME)) {
                this.myDevice = device;
                break;
            }
        }

This method however relies on the name of the device which to me seems dirty and bad :)
is there a better way to do this?
I tried looking at all the methods of BluetoothDevice but none seemed to help - is the name really the best way to do it?
I saw that in some places people say that I should use UUIDs but that is used to open the socket to the device once I have it:

            _socket = myDevice.createRfcommSocketToServiceRecord(MY_UUID);

is there a better way to do it?

相同种类/功能和/或品牌的设备通常具有相似的名称。例如，所有 Roving Networks 的 RN-41 设备均具有以下名称：

FireFly-XXXX

其中 XXXX 是设备地址的最后 4 位数字。这意味着您可以使用以下内容连接到其中的任何：

        if (device.getName().startsWith("FireFly-")) {
            this.myDevice = device;
            break;
        }

这正是我在我的应用程序中所做的，但尚未找到任何更可靠/一致的方法来执行此操作。一般来说，如果您感兴趣的设备中的名称比上面的示例更复杂，您应该能够使用常规模式。

Devices of the same kind/functionality and/or brand will usually have a similar name. For example, all RN-41 devices from Roving Networks have the following name:

FireFly-XXXX

where XXXX is the last 4 digits of the device's address. That means you can use the following to connect to any of them:

        if (device.getName().startsWith("FireFly-")) {
            this.myDevice = device;
            break;
        }

This is exactly what I do in my app and haven't found any more reliable/consistent way to do it. As a generalization, you should be able to use a regular pattern if the name in the devices you are interested in is any more complex than the example above.
