Bluetooth RFCOMM connection: read serial data from com port in Windows 7
提问by gavinmh
I am working with the Android Bluetooth Chat sample application. I am trying to read serial data from the Android device in Windows 7.
我正在使用 Android 蓝牙聊天示例应用程序。我正在尝试从 Windows 7 中的 Android 设备读取串行数据。
I have been able to pair the Android device to the Bluetooth adapter on my laptop. I replaced the UUID in the sample application with the following per some other discussions:
我已经能够将 Android 设备与笔记本电脑上的蓝牙适配器配对。根据其他一些讨论，我用以下内容替换了示例应用程序中的 UUID：
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
When I run the Android application I am able to connect to the laptop. In the "Hardware" properties of my Android device there is a "Device Function" entry called "Standards Serial over Bluetooth link (COM10)". When I attempt to connect CoolTerm to COM10 I receive "error 1168" (there is no additional description for the error).
当我运行 Android 应用程序时，我能够连接到笔记本电脑。在我的 Android 设备的“硬件”属性中，有一个名为“蓝牙链接标准串行 (COM10)”的“设备功能”条目。当我尝试将 CoolTerm 连接到 COM10 时，我收到“错误 1168”（没有对该错误的额外描述）。
Am I misunderstanding something about the process of sending serial data via Bluetooth to a Windows com port?
我是否误解了通过蓝牙将串行数据发送到 Windows com 端口的过程？

Be sure that you are selecting the correctCOM. In my last Android application that required SPP (Serial Port Profile) Bluetooth communication, when Windows 7 paired I had several COM's open up.
确保您选择了正确的COM。在我上一个需要 SPP（串行端口配置文件）蓝牙通信的 Android 应用程序中，当 Windows 7 配对时，我打开了几个 COM。
If COM10 is not working, verify that it is the "incoming" COM (or maybe it's outgoing, I can't remember b/c it's been a few months).
如果 COM10 不工作，请确认它是“传入”COM（或者它可能是传出的，我不记得 b/c 已经几个月了）。

You have to use the proper Bluetooth API from your Windows application to call and connect to your Android device, that is:
您必须使用 Windows 应用程序中正确的蓝牙 API 来调用并连接到您的 Android 设备，即：
- do an 'Inquiry' of all nearby devices, discoverable and exposing an SPP service/profile (SPP=Serial Profile Protocole). This profile has the aforementioned GUID {00001101-0000-1000-8000-00805F9B34FB}
- once all found, select the one you're searching for (either by Name or MacAdress)
- at this point, you can do a 'Discovery' of its Services and check out that it has the proper service exposed (SPP or RFCOMM)
- then connect to it, using the Bluetooth socket API...
- 对附近的所有设备进行“查询”，可发现并公开 SPP 服务/配置文件（SPP=串行配置文件协议）。此配置文件具有上述 GUID {00001101-0000-1000-8000-00805F9B34FB}
- 全部找到后，选择您要搜索的那个（按名称或 MacAdress）
- 此时，您可以对其服务进行“发现”并检查它是否公开了适当的服务（SPP 或 RFCOMM）
- 然后使用蓝牙套接字 API 连接到它...
