如何在Windows上使用PowerShell脚本连接和断开蓝牙设备

我有一台非常慢、相对便宜的电脑,当我打开它时,我打开了我的蓝牙鼠标,鼠标工作正常几秒钟,然后连接断开,如果我然后重新连接鼠标,它就像它应该的那样工作,直到我再次关闭它。

我有一台非常慢、相对便宜的电脑,当我打开它时,我打开了我的蓝牙鼠标,鼠标工作正常几秒钟,然后连接断开,如果我然后重新连接鼠标,它就像它应该的那样工作,直到我再次关闭它。

我的目标是:我想写一个 PowerShell 脚本,将自动重新连接鼠标,但我不知道它是如何与蓝牙在 PowerShell 中。

尝试这样的事情,请注意,提升权限是必需的:

$device = Get-PnpDevice -class Bluetooth -friendlyname "FriendlyDeviceName"
Disable-PnpDevice -InstanceId $device.InstanceId -Confirm:$false
Start-Sleep -Seconds 10
Enable-PnpDevice -InstanceId $device.InstanceId -Confirm:$false

此脚本禁用设备,并在 10 秒后再次启用它。

试试这个 Powershell 脚本,它会禁用并取消配对蓝牙外设(source)。非常感谢 xzion14!

$Source = @"
   [DllImport("BluetoothAPIs.dll", SetLastError = true, CallingConvention = CallingConvention.StdCall)]

   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;
   }
