编写蓝牙检测程序需要根据所使用的编程语言和平台选择合适的库和方法。以下是几种不同编程语言和平台的蓝牙检测程序示例:
1. C 示例程序
```csharp
using System;
using System.Management;
using InTheHand.Net.Bluetooth;
class Program
{
static void Main()
{
try
{
// 获取本地蓝牙适配器
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.DefaultAdapter;
if (bluetoothAdapter == null)
{
Console.WriteLine("未找到蓝牙适配器");
return;
}
// 检查蓝牙是否打开
if (!bluetoothAdapter.IsEnabled)
{
Console.WriteLine("蓝牙未打开");
return;
}
// 获取附近的蓝牙设备
Console.WriteLine("发现以下蓝牙设备:");
foreach (BluetoothDevice device in bluetoothAdapter.GetNearbyDevices())
{
Console.WriteLine(device.DeviceName);
}
}
catch (Exception ex)
{
Console.WriteLine("发生错误:" + ex.Message);
}
}
}
```
2. Python 示例程序
```python
import bluetooth
import time
import sys
def check_bluetooth_status():
"""检查系统蓝牙状态"""
try:
获取本地蓝牙设备
nearby_devices = bluetooth.discover_devices(lookup_names=True)
print(f"发现 {len(nearby_devices)} 个蓝牙设备")
return True
except bluetooth.BluetoothError as e:
print(f"蓝牙初始化失败: {e}")
return False
def scan_devices():
"""扫描周围的蓝牙设备"""
class BluetoothScanner:
def __init__(self):
self.devices = []
def start(self):
try:
bluetooth.set_default_adapter(bluetooth.get_local_adapter())
self.devices = bluetooth.discover_devices(lookup_names=True, duration=10, flush=True)
print("扫描完成")
except bluetooth.BluetoothError as e:
print(f"扫描失败: {e}")
def get_devices(self):
return self.devices
示例使用
if __name__ == "__main__":
if check_bluetooth_status():
scanner = BluetoothScanner()
scanner.start()
devices = scanner.get_devices()
for device in devices:
print(device)
```
