我有Radius网络的蓝牙按钮。内置 - "添加蓝牙设备"每次都找到它。
我需要api或堆栈,我可以用来从我的应用程序做。我在c#中这样做。图书馆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)));
要连接到第一个可用设备,请执行以下操作:
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
}
要将数据发送到设备并读回数据,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
这适用于所有RFCOMM(普通)蓝牙设备,如果您的设备使用蓝牙低功耗,请使用相应的GATT类。
