unity怎么获取蓝牙设备

在Unity中获取蓝牙设备的过程可以分为以下几个步骤:
1. 导入蓝牙插件:在Unity Asset Store中搜索并下载“Bluetooth LE for iOS, Android, and Windows”插件,并导入到您的Unity项目中。
2. 初始化蓝牙:在您的脚本中,使用BluetoothLEHardwareInterface.Initialize()方法初始化蓝牙硬件。
3. 扫描蓝牙设备:使用BluetoothLEHardwareInterface.ScanForPeripherals()方法扫描可用的蓝牙设备,并在找到设备时调用回调函数。
4. 连接蓝牙设备:使用BluetoothLEHardwareInterface.ConnectToPeripheral()方法连接到您选择的蓝牙设备。连接成功后,您可以使用BluetoothLEHardwareInterface.SubscribeCharacteristic()方法订阅蓝牙设备的特征来接收数据。
下面是一个获取蓝牙设备的示例代码:
```
using UnityEngine;
using System.Collections.Generic;
using System;
public class BluetoothManager : MonoBehaviour
{
private List<string> deviceList = new List<string>();
private bool isScanning = false;
void Start()
{
BluetoothLEHardwareInterface.Initialize(true, false, () => {
Debug.Log("Bluetooth initialized");
}, (error) => {
Debug.Log("Error: " + error);
});
}
public void Scan()
{
if (!isScanning)
{
isScanning = true;
deviceList.Clear();
BluetoothLEHardwareInterface.ScanForPeripheralsWithServices(null, (address, name) => {
if (!deviceList.Contains(address))
{
deviceList.Add(address);
Debug.Log("Found device: " + name + " (" + address + ")");
}
}, (address, name, rssi, advertisingInfo) => {
});
}
}
public void Connect(string address)
{
BluetoothLEHardwareInterface.ConnectToPeripheral(address, null, null, (address, serviceUUID, characteristicUUID) => {
Debug.Log("Connected to device: " + address);
BluetoothLEHardwareInterface.SubscribeCharacteristic(address, serviceUUID, characteristicUUID, null, (address, characteristicUUID, data) => {
Debug.Log("Received data: " + data);
});
});
}
}
```
这是一个简单的蓝牙设备管理器,它可以扫描和连接蓝牙设备,并在接收到数据时打印数据。您可以将此代码添加到您的Unity项目中,并根据需要进行修改。
