win10 蓝牙无法删除 完美解决方案

问题描述

win10 蓝牙设备显示已配对，但是无法连接，且无法删除，在设备管理器界面卸载蓝牙设备和卸载驱动无效，重启后又全部回来了。

解决方案

下面提供两种方法，可以都试一下，亲测有效

方法一

1. 下载 修复工具，一路默认选项完成安装。防止链接失效，附上 百度网盘链接
2. 打开 Powershell，命令行输入 btpair -u，回车执行
3. 等待会，就可以去设置把蓝牙设备删除了

方法二

1. 打开 Powershell，命令行输入执行下面的代码

$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))}}
}

################## Execution Begins Here ################

$BTR       = Add-Type -MemberDefinition $Source -Name "BTRemover"  -Namespace "BStuff" -PassThru
$BTDevices = @(Get-BTDevice) # Force array if null or single item
Do {
   If ($BTDevices.Count) {
      "`n******** Bluetooth Devices ********`n" | Write-Host
      For ($i=0; $i -lt $BTDevices.Count; $i++) {
         ('{0,5} - {1}' -f ($i+1), $BTDevices[$i].FriendlyName) | Write-Host
      }
      $selected = Read-Host "`nSelect a device to remove (0 to Exit)"
      If ([int]$selected -in 1..$BTDevices.Count) {
         'Removing device: {0}' -f $BTDevices[$Selected-1].FriendlyName | Write-Host
         $Result = $BTR::Unpair($BTDevices[$Selected-1].Address)
         If (!$Result) {"Device removed successfully." | Write-Host}
         Else {"Sorry, an error occured." | Write-Host}
      }
   }
   Else {
      "`n********* No devices foundd ********" | Write-Host
   }
} While (($BTDevices = @(Get-BTDevice)) -and [int]$selected)

2. 执行完后，选择你要删除的设备，然后就可以去设置里把蓝牙设备删除了
