要在C#中从蓝牙设备获取数据,你需要使用.NET Framework提供的Bluetooth API。以下是一个简单的代码示例:
```csharp
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO.Ports;
using InTheHand.Net.Sockets;
using InTheHand.Net.Bluetooth;
namespace BluetoothDemo
{
class Program
{
static void Main(string[] args)
{
// 获取本机蓝牙设备列表
BluetoothClient client = new BluetoothClient();
BluetoothDeviceInfo[] devices = client.DiscoverDevices();
// 选择要连接的设备
BluetoothDeviceInfo device = null;
foreach (BluetoothDeviceInfo d in devices)
{
if (d.DeviceName == "MyDeviceName")
{
device = d;
break;
}
}
if (device != null)
{
// 连接设备
BluetoothClient client2 = new BluetoothClient();
BluetoothEndPoint ep = new BluetoothEndPoint(device.DeviceAddress, BluetoothService.SerialPort);
BluetoothClient client3 = new BluetoothClient();
client3.Connect(ep);
// 打开串口通信
SerialPort serialPort = new SerialPort();
serialPort.PortName = "COM1"; // 选择一个未使用的串口号
serialPort.BaudRate = 9600;
serialPort.Parity = Parity.None;
serialPort.DataBits = 8;
serialPort.StopBits = StopBits.One;
serialPort.Open();
// 从蓝牙设备读取数据并输出到控制台
while (true)
{
if (serialPort.BytesToRead > 0)
{
Console.Write((char)serialPort.ReadByte());
}
}
// 关闭串口通信
serialPort.Close();
}
else
{
Console.WriteLine("Device not found.");
}
Console.ReadLine();
}
}
}
```
注意,你需要在项目中引用`InTheHand.Net.Personal.dll`和`InTheHand.Net.Sockets.dll`。此外,你需要将`MyDeviceName`替换为你要连接的蓝牙设备的名称。
