我正在尝试在 C# 中开发一个应用程序,它充当 Android 手机的服务器。我在 C# 中将 32feet.net 用于蓝牙,我有一个在 android 中运行的服务器,它只是向服务器发送一个套接字。在 pc 中运行的服务器需要监听连接并显示连接状态。所有这些都是我项目的基础。服务器代码如图所示:
namespace testserver
{
class Program
{
static void Main(string[] args)
{
BluetoothClient bc = new BluetoothClient();
BluetoothDeviceInfo[] dev;
BluetoothDeviceInfo td=null;
Guid id = new Guid("{00112233-4455-6677-8899-aabbccddeeff}");
// Console.WriteLine(id.ToString());
// Console.Read();
dev = bc.DiscoverDevices();
foreach (BluetoothDeviceInfo d in dev)
{
if (d.DeviceName == "ST21i")//my phone name
{
td=d;
break;
}
}
try
{
BluetoothAddress addr = td.DeviceAddress;
BluetoothListener bl = new BluetoothListener(addr, id);
bl.Start();
if (bl.AcceptSocket() != null)
Console.WriteLine("Success");
}
catch (Exception e)
{
Console.WriteLine("Exception : "+e.Message);
Console.Read();
}
}
}
}
这是我的安卓代码:
public class MainActivity extends Activity {
BluetoothAdapter adapter;
BluetoothDevice bd;
BluetoothSocket sock;
OutputStream ostr;
int REQUEST_ENABLE_BT;
String str="5C:AC:4C:DD:CC:0D";
private static final UUID id=UUID.fromString("00112233-4455-6677-8899- aabbccddeeff");
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
adapter=BluetoothAdapter.getDefaultAdapter();
if (!adapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "clicked button", Toast.LENGTH_LONG).show();
try
{
bd=adapter.getRemoteDevice(str); Toast.makeText(getApplicationContext(),"Server is running at "+bd.getName().toString()+"...", Toast.LENGTH_LONG).show();
sock=bd.createInsecureRfcommSocketToServiceRecord(id); sock.connect();
ostr=sock.getOutputStream();
ostr.write(0);
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(),e.getMessage(), Toast.LENGTH_LONG).show();
}
}
});
}
}
我的问题是:
1)在 pc 中我遇到异常,请求的地址在其上下文中无效(因此服务器无法运行) 2)在电话中,服务发现失败(因为服务器不可用)
如何更正服务器并运行程序?
