C# 适用于surface pro 3 windows 8.1的蓝牙api

我有一个来自Radius网络的蓝牙按钮。内置的“添加蓝牙设备”每次都会找到它

我需要的api或堆栈，我可以用来做从我的应用程序。我用c#做这件事。库32英尺不兼容

要枚举连接到设备的RFCOMM蓝牙设备，请执行以下操作：

var DEVICE_ID = new Guid("{00000000-0000-0000-0000-000000000000}"); //Enter your device's RFCOMM service id (try to find it on manufactorer's website
var services = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(
        RfcommDeviceService.GetDeviceSelector(
            RfcommServiceId.FromUuid(DEVICE_ID)));

if (services.Count > 0) 
{
   var service = await RfcommDeviceService.FromIdAsync(services[0].Id);
   //Open a socket to the bluetooth device for communication. Use the socket to communicate using the device's API
   var socket = new StreamSocket();
   await socket.ConnectAsync(service.ConnectionHostName, service.ConnectionServiceName, SocketProtectionLevel
                .BluetoothEncryptionAllowNullAuthentication); //Substitue real BluetoothEncryption
}

要连接到第一个可用设备，请执行以下操作：

var DEVICE_ID = new Guid("{00000000-0000-0000-0000-000000000000}"); //Enter your device's RFCOMM service id (try to find it on manufactorer's website
var services = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(
        RfcommDeviceService.GetDeviceSelector(
            RfcommServiceId.FromUuid(DEVICE_ID)));

if (services.Count > 0) 
{
   var service = await RfcommDeviceService.FromIdAsync(services[0].Id);
   //Open a socket to the bluetooth device for communication. Use the socket to communicate using the device's API
   var socket = new StreamSocket();
   await socket.ConnectAsync(service.ConnectionHostName, service.ConnectionServiceName, SocketProtectionLevel
                .BluetoothEncryptionAllowNullAuthentication); //Substitue real BluetoothEncryption
}

要向设备发送数据并读回数据，请执行以下操作：

var BYTE_NUM = 64 as UInt32; //Read this many bytes
IInputStream input = socket.InputStream;
IOutputStream output = socket.OutputStream;
var inputBuffer = new Buffer();
var operation = input.ReadAsync(inputBuffer, BYTE_NUM, InputStreamOptions.none);
while (!operation.Completed) Thread.Sleep(200);
inputBuffer = operation.GetResults();
var resultReader = DataReader.FromBuffer(inputBuffer);
byte[] result = new byte[BYTE_NUM];
resultReader.ReadBytes(result);
resultReader.Dispose();
//Do something with the bytes retrieved. If the Bluetooth device has an api, it will likely specify what bytes will be sent from the device
//Now time to give some data to the device
byte[] outputData = Encoding.ASCII.GetBytes("Hello, Bluetooth Device. Here's some data! LALALALALA");
IBuffer outputBuffer = outputData.AsBuffer(); //Neat method, remember to include System.Runtime.InteropServices.WindowsRuntime
operation = output.WriteAsync(outputBuffer);
while (!operation.Completed) Thread.Sleep(200);
await output.FlushAsync(); //Now the data has really been written

这将适用于所有RFCOMM（正常）蓝牙设备，如果您的设备使用蓝牙低能量，请使用相应的GATT类。

同样，您似乎是uwp。我想在uwp之外解决这个问题
