连接到蓝牙设备/如何设置RFCOMM能力

问题描述

我试图连接到蓝牙设备

我已经配对它，当我搜索它，我发现它：

I have paired it and when I search for it I find it :

private async void Grid_DoubleTapped(object sender, DoubleTappedRoutedEventArgs e)
{
    ListBox1.Items.Clear();
    var devices = await DeviceInformation.FindAllAsync(RfcommDeviceService.GetDeviceSelector(RfcommServiceId.SerialPort));
    var device = devices.FirstOrDefault(c => c.Name.Contains("BMMTCA32"));

    foreach (var element in device.Properties)
    {
        var strMessage = element.Key + (element.Value == null ? "" : " = " + element.Value.ToString());
        ListBox1.Items.Add(strMessage);
    }
}

下面是我的列表框的输出：

Here is the output in my ListBox:

System.ItemNameDisplay = BMMTCA32-01
System.Devices.DeviceInstanceId = BTHENUM\{00001101-0000-1000-8000-00805f9b34fb}_LOCALMFG&0048\8&f358302&0&0012F31DECF3_C00000000
System.Devices.Icon = C:\Windows\System32\DDORes.dll,-2001
{51236583-0C4A-4FE8-B81F-166AEC13F510} 123 = C:\Windows\SYSTEM32\DDORes.dll,-3001
System.Devices.InterfaceEnabled = True
System.Devices.IsDefault = False
System.Devices.PhysicalDeviceLocation

但我的问题是如何连接呢？

But my problem is how to connect to to it?

当我尝试Googeling它我得到这样的答案你设置RFCOMM能力？看到了解一些细节。

When I try Googeling for it I get answers like Did you set the rfcomm capability? see http://msdn.microsoft.com/en-us/library/windows/apps/dn263090.aspx for some details.

但是，当我看着网页我迷路了，因为我没有什么要在清单文件中写入。

But when I look at that page I get lost because I don't what to write in the manifest file.

因此​​，在短期：我如何连接到设备？

so in short: How do I connect to the device?

PS：这是一个Windows平板节目

PS: It is a Windows Tablet program.

推荐答案

所以，你想知道你有什么在清单文件中写入，以及如何连接？

So you want to know what you have to write in the manifest file, as well as how to connect?

清单文件：

   <m2:DeviceCapability Name="bluetooth.rfcomm">
      <m2:Device Id="any">
        <m2:Function Type="serviceId:00001101-0000-1000-8000-00805F9B34FB"/>
      </m2:Device>
    </m2:DeviceCapability>

• 您可以在保持标识的。


• 功能类型既可以是的名称：的SerialPort或在本例中指定的服务ID


• You can keep Id at "any".
• Function type could either be "name:serialPort" or the serviceId specified in the example.

连接：

StreamSocket _socket;
RfcommDeviceService service = await RfcommDeviceService.FromIdAsync(device.id);
await _socket.ConnectAsync(service.ConnectionHostName, service.ConnectionServiceName);

应该可以做的伎俩。

Should be able to do the trick.
