unity 在win10平台 添加一个搜索蓝牙的C#代码

在Unity中搜索蓝牙需要使用Windows Runtime API,具体代码如下:
```csharp
using System;
using System.Collections.Generic;
using UnityEngine;
using Windows.Devices.Bluetooth;
using Windows.Devices.Enumeration;
public class BluetoothController : MonoBehaviour
{
private BluetoothLEDevice _device;
private DeviceWatcher _watcher;
private List<DeviceInformation> _deviceList = new List<DeviceInformation>();
void Start()
{
// 初始化设备列表
InitializeDeviceList();
}
void OnDestroy()
{
if (_watcher != null)
{
_watcher.Stop();
_watcher = null;
}
}
public void ScanDevices()
{
// 清空设备列表
_deviceList.Clear();
// 创建设备查找器
_watcher = DeviceInformation.CreateWatcher(
BluetoothLEDevice.GetDeviceSelectorFromPairingState(false),
new string[] { "System.Devices.Aep.DeviceAddress", "System.Devices.Aep.IsConnected" },
DeviceInformationKind.AssociationEndpoint);
// 注册设备查找事件
_watcher.Added += OnDeviceAdded;
_watcher.Removed += OnDeviceRemoved;
_watcher.Updated += OnDeviceUpdated;
_watcher.EnumerationCompleted += OnEnumerationCompleted;
// 开始查找设备
_watcher.Start();
}
private async void InitializeDeviceList()
{
// 获取所有已配对的蓝牙设备
var devices = await DeviceInformation.FindAllAsync(BluetoothDevice.GetDeviceSelectorFromPairingState(true));
foreach (var device in devices)
{
_deviceList.Add(device);
}
}
private void OnDeviceAdded(DeviceWatcher sender, DeviceInformation deviceInfo)
{
_deviceList.Add(deviceInfo);
}
private void OnDeviceRemoved(DeviceWatcher sender, DeviceInformationUpdate deviceInfoUpdate)
{
var device = _deviceList.Find(d => d.Id == deviceInfoUpdate.Id);
if (device != null)
{
_deviceList.Remove(device);
}
}
private void OnDeviceUpdated(DeviceWatcher sender, DeviceInformationUpdate deviceInfoUpdate)
{
// TODO: 更新设备信息
}
private void OnEnumerationCompleted(DeviceWatcher sender, object args)
{
// 停止设备查找
_watcher.Stop();
_watcher = null;
// TODO: 设备查找完成
}
}
```
使用时,只需要调用`ScanDevices`方法即可开始搜索蓝牙设备。在`InitializeDeviceList`方法中可以获取已配对的蓝牙设备列表,方便后续连接设备。
