unity 在windows系统搜索蓝牙方法

在Unity中搜索蓝牙设备需要使用C#编写代码。以下是一些基本的步骤：

1. 首先，你需要导入Unity的BluetoothLE插件。这可以通过Unity Asset Store或其他插件商店来获得。

2. 然后，你需要在代码中使用BluetoothLE插件的API来扫描蓝牙设备。这可以通过调用BluetoothLEDeviceManager.StartScan()方法来实现。

3. 在扫描期间，你需要处理BluetoothLEDeviceManager.OnDeviceDiscovered事件，以便在发现新设备时进行处理。

4. 在处理事件时，你可以使用BluetoothLEDeviceManager.GetDeviceByName()或BluetoothLEDeviceManager.GetDeviceByAddress()方法来获取设备引用，然后使用它来执行其他操作，例如连接或读取数据。

下面是一些示例代码，用于在Unity中搜索蓝牙设备：

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.XR.WSA.Input;
using UnityEngine.XR.WSA.WebCam;
using System.Linq;
using System;
using System.Threading.Tasks;
using System.Collections;
using UnityEngine.Networking;
using Unity.Notifications.Android;
using System.Text;

public class BluetoothLE : MonoBehaviour
{
    // Reference to the BluetoothLE device manager
    private BluetoothLEDeviceManager deviceManager;

    // Reference to the text UI element for displaying device information
    public Text deviceInfoText;

    // Reference to the button UI element for starting the scan
    public Button startScanButton;

    // Reference to the button UI element for stopping the scan
    public Button stopScanButton;

    // List of discovered devices
    private List<BluetoothLEDevice> discoveredDevices = new List<BluetoothLEDevice>();

    // Flag indicating whether a scan is currently in progress
    private bool isScanning = false;

    // Called when the script is first enabled
    private void OnEnable()
    {
        // Initialize the device manager
        deviceManager = BluetoothLEDeviceManager.GetManager();

        // Register event handlers
        deviceManager.OnDeviceDiscovered += OnDeviceDiscovered;

        // Disable the stop scan button at start
        stopScanButton.interactable = false;
    }

    // Called when the script is disabled
    private void OnDisable()
    {
        // Unregister event handlers
        deviceManager.OnDeviceDiscovered -= OnDeviceDiscovered;
    }

    // Called when the start scan button is clicked
    public void OnStartScanButtonClick()
    {
        // Clear the list of discovered devices
        discoveredDevices.Clear();

        // Start the scan
        deviceManager.StartScan();

        // Update the UI
        isScanning = true;
        startScanButton.interactable = false;
        stopScanButton.interactable = true;
    }

    // Called when the stop scan button is clicked
    public void OnStopScanButtonClick()
    {
        // Stop the scan
        deviceManager.StopScan();

        // Update the UI
        isScanning = false;
        startScanButton.interactable = true;
        stopScanButton.interactable = false;
    }

    // Called when a device is discovered during a scan
    private void OnDeviceDiscovered(BluetoothLEDevice device)
    {
        // Add the device to the list of discovered devices
        discoveredDevices.Add(device);

        // Update the UI with device information
        StringBuilder sb = new StringBuilder();
        sb.AppendLine("Device discovered:");
        sb.AppendLine("Name: " + device.Name);
        sb.AppendLine("Address: " + device.Address);
        sb.AppendLine("Signal strength: " + device.SignalStrength);
        sb.AppendLine("Service UUIDs: " + string.Join(", ", device.ServiceUUIDs));
        deviceInfoText.text = sb.ToString();
    }
}

这个脚本包括了开始和停止扫描的按钮，并在发现设备时更新UI界面。你可以自定义代码以适应你的需求。
