蓝牙问题

最近调试蓝牙 HID设备，发现蓝牙连接一次就不能再次连接，只能通过修改蓝牙mac地址重新连接，这就出现个问题，每修改一次程序就要修改一次mac地址，设备管理器就会多一个设备几次调试，蓝牙设备如下图所示：

1、使用工具删除

控制台删除法：复制下面程序粘贴到控制台运行。

$Source = @"
   [DllImport("BluetoothAPIs.dll", SetLastError = true, CallingConvention = CallingConvention.StdCall)]
   [return: MarshalAs(UnmanagedType.U4)]
   static extern UInt32 BluetoothRemoveDevice(IntPtr pAddress);

   public static UInt32 Unpair(UInt64 BTAddress) {
      GCHandle pinnedAddr = GCHandle.Alloc(BTAddress, GCHandleType.Pinned);
      IntPtr pAddress     = pinnedAddr.AddrOfPinnedObject();

      UInt32 result       = BluetoothRemoveDevice(pAddress);
      pinnedAddr.Free();
      return result;
   }
"@

Function Get-BTDevice {
    Get-PnpDevice -class Bluetooth |
      ?{$_.HardwareID -match 'DEV_'} |
         select Status, Class, FriendlyName, HardwareID,
            # Extract device address from HardwareID
            @{N='Address';E={[uInt64]('0x{0}' -f $_.HardwareID[0].Substring(12))}}
}
