通过蓝牙从 android 设备向笔记本电脑发送字符串

Question

我正在从事一个项目，该项目涉及将字符串从 android phone 发送到我的笔记本电脑运行 32 位 windows VM (VMWare Fusion)。在对如何做这样的事情进行了一些搜索之后，我让客户端 (phone) 开始工作，但是对于服务器（笔记本电脑）端，它似乎从来没有收到任何东西。

我正在与 VM 共享蓝牙，并且设备已与主机配对，但当我发送数据时它会连接到主机，但 VM 运行 "server" 似乎从来没有收到。

我从 here 那里得到了接收器的代码，但只是为了澄清，这里是我用于 receiver/server/VM 的代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;

import javax.bluetooth.RemoteDevice;
import javax.bluetooth.UUID;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;
import javax.microedition.io.StreamConnectionNotifier;

public class server {
    // TODO: Update this to use the window, instead of the console
    public void startServer() throws IOException {

        // Create a UUID for SPP
        UUID uuid = new UUID("1101", true);
        //UUID uuid = new UUID("00001101-0000-1000-8000-00805F9B34FB", false);
        // Create the servicve url
        String connectionString = "btspp://localhost:" + uuid + ";name=SpudSPPServer";

        // open server url
        StreamConnectionNotifier streamConnNotifier = (StreamConnectionNotifier) Connector.open(connectionString);

        // Wait for client connection
        System.out.println("\nServer Started. Waiting for clients to connect…");
        StreamConnection connection = streamConnNotifier.acceptAndOpen();

        RemoteDevice dev = RemoteDevice.getRemoteDevice(connection);
        System.out.println("Remote device address: " + dev.getBluetoothAddress());
        System.out.println("Remote device name: " + dev.getFriendlyName(true));

        // read string from spp client
        InputStream inStream = connection.openInputStream();
        BufferedReader bReader = new BufferedReader(new InputStreamReader(inStream));
        String lineRead = bReader.readLine();
        System.out.println(lineRead);

        // send response to spp client
        OutputStream outStream = connection.openOutputStream();
        PrintWriter pWriter = new PrintWriter(new OutputStreamWriter(outStream));
        pWriter.write("Response String from SPP Server\r\n");
        pWriter.flush();
        pWriter.close();

        streamConnNotifier.close();

    }
}

& 在主文件中：

public static void main(String args[]) throws IOException {

    display d  = new display();
    server blueToothServer = new server();
    d.makePanel();
    if (selectFile.fileMissing()) {
        d.feed.setText("File missing, creating new file");
        selectFile.makeFile();
        d.feed.setText("File created! Awaiting data...");
    } else {
        d.feed.setText("File found! Awaiting data...");
        d.MACAddress.setText("MAC Address: " + LocalDevice.getLocalDevice().getBluetoothAddress().replace("-", ":").toUpperCase());
    }

    blueToothServer.startServer();

}

如果您需要客户端的代码 (phone)，我可以 post 如果被问到

搞清楚了，原来是在 VM 端，所以我只是正常安装 windows 而不是 VM，然后修复了它
