This just happened to me too NUC5I5RYH. Updated to latest Bluetooth driver from Intel's site. So Bluetooth is enabled in Device manager, but is totally missing from Devices and system tray. Discovered problem when logitech bluetooth keyboard stopped working.
Even though you mentioned you already try to install the Bluetooth drivers again, please try the following:
If that one does not work please try the following:
Just to make sure, the BIOS version that you have is it 0042?
Did you try to pair the Bluetooth mouse from scratch?
The Intel® driver update is not always that accurate when it comes to drivers updates, that is why we recommend to install the drivers manually, on this link you will be able to see all the drivers for the NUC:
Please let me know the results of trying the steps above.
Any questions, please let me know.
Thanks for reply, but it didn't help. Actually I already have this version of Bluetooth drivers.
For the second driver you sent me link to, it upgraded successfully, but nothing happened with Bluetooth. As for other drivers, all install successfully if manually, but update utility don't think so. And when I go to see driver version in device manager, it also says they are not updated.
I hope it can not be that Bluetooth is somehow physically not working?
Do you have the option to use a different Bluetooth mouse?
Did you try to install this chipset driver?
Is the BIOS version on the NUC 0042?
Any further questions, please let me know.
I don't have another Bluetooth mouse, but I have Bluetooth headphones, and they also not working because Bluetooth settings and devices completely missing.
Yes, my BIOS version is 0042.
I tried installing this Chipset driver many times but it didn't really installing. According to the logs, installation is reverting to repair somehow.
Very interesting. When I was playing Watch Dogs 2 suddenly all stopped, music started lagging, and no reaction to mouse or keyboard. When I rebooted, Bluetooth somehow returned.
I'm also a user of the NUK6i7KYK2 and yesterday evening, my bluetooth suddenly stop working exactly as described by Necros4. Like him, I tried to desactivate and reactivate BT (toggle switch in Win10) and then, the bluetooth menu completely dissapears from Windows 10 !
I losted my BT mouse (Logitech) and BT keyboard (microsoft).
I tried removing and reinstalling the last Intel BT driver version (19.11.1639.0649) + reboot without retreiving the BT feature from windows 10
I also tried to install last ".inf" version from Intel server without inprovement on the issue...
My Bios is last (up to date) version too. I couldn't understand why this issue occurs since I've been using BT from several months (each day use) without any issue until yesterday.
Please advise what I can do to retreive the input devices of my PC
Yes, very interesting indeed.
It is great to hear that the Bluetooth feature is working fine again.
Please let me know if you need further assistance on this matter.
To JohnHWman and Hdowin :
If you tried the steps provided on this thread and the issue persists, then the next step to do will be to un-install and re-install Windows from scratch, make sure to back up the important information before you do that.
If the problem persists after that, could you please submit a new thread? This is because we might need to start an investigation on your specific case and every scenario is different even if the same product is being used,
So, even if your problem is the same, by starting a new thread, we can actually get a better scenario of the problem, and also we will be able to provide a better and more accurate solution in order to fix the NUC or in case it needs to be replaced.
Let me apologize for any inconvenience.
FYI, I've finaly decided to follow Amy's 6 steps suggestion on the thread : Re: NUC6i7KYK Bluetooth yellow bang dated on 4 oct. 2016 08:22 and after Windows 10 restart, I've recovered the BT feature within Windows 10
--> I've completely uninstalled the Intel BT driver version (19.11.1639.0649) for the BT devices list !
I checked my Microsoft BT keyboard and it was working fine again ! Not my Logitech MX master...
Then, I've lauched the Peripheral device manager and openned the BT branch to remove my Logitech MX Master mouse item yellow error, then do repairing it through the Windows BT devices manager and my two BT peripherals were online again and working fine !!
I did NOT re-installed the Intel "BT_19.11.1639_64_Win10" driver but all is working fine without it
I assume that something is going wrong with this Intel 19.11.1639.0649 device driver version I suggest to search on this path for Intel software team !
With kind regards
