HP Support Assistant keeps offering driver update for Realtek Bluetooth 4.2 Adapter, then takes it back saying it is dismissed.


I have gotten the following Bluetooth Warning in Event Viewer since I turned this Windows 10 Pavilion Desktop on:

BTHUSB Event ID 34 - The local adapter does not support an important Low Energy controller state to support peripheral mode.  The minimum required supported state mask is 0x2491f7fffff, got 0xffffffff.  Low Energy peripheral role functionality will not be available.


I never could find any info on the problem and just turned Bluetooth off to get rid of the Event Log Warning.


I turned this computer on for first time 1/28/2020 and Windows 10v1909 loaded and it is the only version I have ever had. I turned Bluetooth off in Windows 10 settings about 2/29/2020.  Warnings stopped and I forgot about it.


A few days ago, HPSA offered an update for Realtek Bluetooth Audio Driver for Microsoft Windows.  SoftPaq number: sp100551 Version 


After it apparently successfully installed a greyed out “Realtek Bluetooth Audio Driver for Microsoft Windows” came up in the history and said it was dismissed and when I mouse over this it says, “This update is not available anymore.”


I looked at the update history in HPSA and the same thing happened with the same update in January and February.  I keep thinking an update will fix the Event ID 34 Warning, but the update that is offered apparently no longer exists.


This time HPSA also offered an update for Realtek High Definition (HD) Audio Driver and it also successfully installed.  SoftPaq number: sp103920 Version: 6.0.8923.1.  (This one apparently exists and a greyed out version did not come up in history.)


About 10 minutes later there were three new devices listed under Bluetooth in Device Manager:

Bluetooth Device (RFCOMM Protocol TDI),

Microsoft Bluetooth Enumerator,

Microsoft Bluetooth LE Enumerator. 

I have no idea where they came from. 


Maybe the Realtek HD driver install or maybe because I turned Bluetooth on to see if I still got the Warning Event.  I don’t know.


The original Realtek Bluetooth 4.2 Adapter is also still there.


The minute the three new devices were installed 5/29/2020 1:33:04 a BTHUSB Warning Event 34 appeared in the Event log.  But only one.  So I clicked restart to see if that would cause another warning event.  Yep.  When computer starts or wakes this event is logged.  That was the pattern before.


Can anyone explain all this?  Do I have a working Bluetooth drive?  I have no Bluetooth devices now but I may in the future and want this fixed before my warranty expires.


Any help or explanation would be greatly appreciated.
