我使用蓝牙连接了Windows Phone 8和使用蓝牙的arudino
这适用于Windows Phone 8但是当我将应用程序重新定位到Windows Phone Silverlight 8.1时,我收到Debugger.Break并继续,我得到异常"调用目标引发异常&#34 ;
我用过代码:
PeerFinder.AlternateIdentities["Bluetooth:Paired"] = "";
var pairedDevices = await PeerFinder.FindAllPeersAsync();
if (pairedDevices.Count == 0)
{
Debug.WriteLine("No paired devices were found.");
}
else
{
foreach (var pairedDevice in pairedDevices)
{
if (pairedDevice.DisplayName == DeviceName.Text)
{
connectionManager.Connect(pairedDevice.HostName);
ConnectAppToDeviceButton.Content = "Connected";
DeviceName.IsReadOnly = true;
ConnectAppToDeviceButton.IsEnabled = false;
continue;
}
}
}
其中connect函数定义为:
public async void Connect(HostName deviceHostName)
{
if (socket != null)
{
await socket.ConnectAsync(deviceHostName, "1");
dataReader = new DataReader(socket.InputStream);
dataReadWorker.RunWorkerAsync();
dataWriter = new DataWriter(socket.OutputStream);
}
}
请帮助我。

您是否尝试过使用Windows.Devices.Bluetooth.Rfcomm命名空间?它几乎是为Windows 8.1蓝牙通信而制作的。
<m2:DeviceCapability Name="bluetooth.rfcomm">
<m2:Device Id="any">
<m2:Function Type="serviceId:00001101-0000-1000-8000-00805F9B34FB"/>
</m2:Device>
</m2:DeviceCapability>
选择设备:这是您必须解析正在使用的设备的Guid的地方。之后,您使用解析的Guid查找提供该服务的每个设备。 (我使用了SerialPort Guid)
Guid RfcommChatServiceUuid = Guid.Parse("00001101-0000-1000-8000-00805F9B34FB");
await DeviceInformation.FindAllAsync(RfcommDeviceService.GetDeviceSelector(RfcommServiceId.FromUuid(RfcommChatServiceUuid)));
连接:DeviceInformation返回DeviceInformation列表。使用chatserviceInfo.Id,您可以创建一个新的RfcommDeviceService。 (在这种情况下,它被称为“服务”)
StreamSocket _socket;
RfcommDeviceService service = await RfcommDeviceService.FromIdAsync(chatserviceInfo1._id);
await _socket.ConnectAsync(service.ConnectionHostName, service.ConnectionServiceName);
断开:
this._socket.Dispose();
this._socket = null;
