Windows (PowerShell)

# 方法1：使用 Get-PnpDevice
Get-PnpDevice -Class Bluetooth | Where-Object {$_.Status -eq "OK"} | 
    Select-Object FriendlyName, DeviceID, Status
# 方法2：查看所有蓝牙设备（包括已配对和连接的）
Get-PnpDevice -Class Bluetooth | 
    Where-Object {$_.InstanceId -like "*DEVICE*"} |
    Select-Object FriendlyName, DeviceID, Status

Windows (CMD/Batch)

@echo off
REM 使用 wmic 命令
wmic path Win32_PnPEntity where "ClassGuid='{e0cbf06c-cd8b-4647-bb8a-263b43f0f974}'" get Name,DeviceID,Status

Linux (Bash)

#!/bin/bash
# 方法1：使用 bluetoothctl
echo "已连接的蓝牙设备："
bluetoothctl devices Connected | cut -d' ' -f3-
# 方法2：使用 hcitool (需要 bluez 工具)
if command -v hcitool &> /dev/null; then
    echo -e "\n通过 hcitool 扫描："
    hcitool con
fi
# 方法3：通过 dbus 获取
echo -e "\n通过 D-Bus 获取："
dbus-send --system --dest=org.bluez --print-reply \
    /org/bluez/hci0 org.freedesktop.DBus.ObjectManager.GetManagedObjects

macOS (Bash)

#!/bin/bash
# 使用 system_profiler
echo "已连接的蓝牙设备："
system_profiler SPBluetoothDataType | grep "Connected:" -A 5 | 
    grep -E "^\s+[A-Za-z]" | sed 's/^[[:space:]]*//'
# 或使用蓝牙命令行工具
/usr/sbin/blued -s 2>/dev/null | grep "Connected"

跨平台 Python 脚本

import subprocess
import platform
import sys
def get_connected_bluetooth():
    system = platform.system().lower()
    if system == "windows":
        return get_windows_bluetooth()
    elif system == "linux":
        return get_linux_bluetooth()
    elif system == "darwin":  # macOS
        return get_macos_bluetooth()
    else:
        print(f"不支持的操作系统: {system}")
        return []
def get_windows_bluetooth():
    try:
        # 使用 PowerShell
        cmd = 'powershell "Get-PnpDevice -Class Bluetooth | Where-Object {$_.Status -eq \'OK\'} | Select-Object FriendlyName"'
        result = subprocess.run(cmd, capture_output=True, text=True, shell=True)
        devices = result.stdout.strip().split('\n')[3:]  # 跳过前3行
        return [d.strip() for d in devices if d.strip()]
    except Exception as e:
        print(f"错误: {e}")
        return []
def get_linux_bluetooth():
    try:
        result = subprocess.run(
            ['bluetoothctl', 'devices', 'Connected'],
            capture_output=True, text=True
        )
        devices = []
        for line in result.stdout.strip().split('\n'):
            if line.startswith('Device'):
                # 格式: Device MAC_ADDRESS Device_Name
                parts = line.split()
                if len(parts) >= 3:
                    devices.append(' '.join(parts[2:]))
        return devices
    except Exception as e:
        print(f"错误: {e}")
        return []
def get_macos_bluetooth():
    try:
        result = subprocess.run(
            ['system_profiler', 'SPBluetoothDataType'],
            capture_output=True, text=True
        )
        output = result.stdout
        devices = []
        lines = output.split('\n')
        is_connected = False
        for i, line in enumerate(lines):
            if 'Connected:' in line:
                is_connected = True
                continue
            if is_connected and line.strip() and not line.startswith(' '):
                is_connected = False
            if is_connected and line.strip() and ':' not in line:
                devices.append(line.strip())
        return devices
    except Exception as e:
        print(f"错误: {e}")
        return []
# 使用示例
if __name__ == "__main__":
    connected_devices = get_connected_bluetooth()
    if connected_devices:
        print("已连接的蓝牙设备：")
        for i, device in enumerate(connected_devices, 1):
            print(f"{i}. {device}")
    else:
        print("未找到已连接的蓝牙设备")

Node.js (需要管理员权限)

const { exec } = require('child_process');
const os = require('os');
function getConnectedBluetooth() {
    return new Promise((resolve, reject) => {
        let cmd;
        const platform = os.platform();
        if (platform === 'win32') {
            cmd = 'powershell "Get-PnpDevice -Class Bluetooth | Where-Object {$_.Status -eq \'OK\'} | Select-Object FriendlyName"';
        } else if (platform === 'linux') {
            cmd = 'bluetoothctl devices Connected';
        } else if (platform === 'darwin') {
            cmd = 'system_profiler SPBluetoothDataType | grep "Connected:" -A 5';
        } else {
            reject(new Error(`不支持的操作系统: ${platform}`));
            return;
        }
        exec(cmd, { encoding: 'utf8' }, (error, stdout, stderr) => {
            if (error) {
                reject(error);
                return;
            }
            resolve(stdout.trim());
        });
    });
}
// 使用示例
getConnectedBluetooth()
    .then(devices => {
        console.log('已连接的蓝牙设备：\n', devices);
    })
    .catch(error => {
        console.error('错误：', error.message);
    });

注意事项

1. Windows：某些命令需要管理员权限
2. Linux：需要安装 bluez 工具包
3. macOS：需要启用蓝牙权限
4. 跨平台：建议使用 Python 脚本，因为它更容易处理不同操作系统

选择最适合你操作系统和需求的脚本即可。
