Win10 蓝牙已配对但无法连接的问题
今天打开笔记本,发现ikbc的dc87键盘的蓝牙怎么也连不上,尝试了在蓝牙设置和设备管理器里删除该设备,后再重新配对,然而无法解决。 sigh… 好吧,决定开始排查问题: 键盘恢复出厂设置,重新请求配对时,win10里的设备列表里已经显示有配对的键盘:HM_KBxairpods能连上电脑,排除了笔记本蓝牙硬件问题键盘能连上手机,排除了键盘蓝牙硬件问题至此,可以判断出是win10系统的问题。问题比较奇葩,我的推断是在win10里没法彻底删除蓝牙设备,其中的现象是我在蓝牙设置删除了HM_KBx后,随后隔几秒钟HM_KBx又出现在列表中,显示的是已配对。 然后找到了这篇救命文章:How to completely remove a Bluetooth device from Win 10? 里面的人也是类似问题,跟着下面的Solution执行一遍,把所有已配对的设备删除之后,再重新配对键盘,fixed! wouldn’t normally necro a thread but i spent two weeks trawling the internet trying to sort this out and this thread is pretty high up on the search rankings, hopefully can help someone. My symptoms: Previously working bluetooth speaker (UE BOOM 2 in my case) stops connectingWindows 10 ‘Bluetooth and other devices’ menu shows the device as PairedPressing connect makes it attempt to connect but fails then it goes back to PairedRemove device hides the device from the menu, but as soon as you turn bluetooth on and off, or restart the computer, the device comes backYou pull your hair out.Solution that worked for me after much, much unsuccessful internet trawling and one system restore: Download this 7 year old command line bluetooth toolset: Bluetooth command line tools - work with bluetooth from the command lineInstall it, make sure you enable the option to “Add Bluetooth Command Line Tools directory to path”Open PowershellPut your device that isn’t working properly into pairing mode WARNING: THE FOLLOWING COMMAND WILL UNPAIR ALL BLUETOOTH DEVICEStype in “btpair -u”Boom, all of a sudden Windows asks me if I want to allow pairing to my device that isn’t workingHit yes, successfully connected againCry tears of joyGod I hope that helps someone else. |
