Bluetooth got error code 43

Hi, when you reinstalled Win 10, what was your build before you reinstalled (e.g. 1709,1809, 1903) and afterwards?I.e. did the major build change? If it it did it's quite likely the build of your driver changed. Again:I.e. look for an older build of your bluetooth driver and try that.
Your laptop seems to date from around 2011 so you are in unspecified territory- no guarantees that Win 10 will work, or as it continues to be updated, will continue to work. It has some drivers for Win 8.1: BIOS latest is 2018.

It would be worth checking your BIOS version (though I'd guess that's unrelated to your bluetooth driver issue).
The driver version there is
Qualcomm Atheros QCA9000 Series Bluetooth 4.0+HS Driver 8.0.1.232
- which doesn't seem to line up with your quoted

Sorry, I don't know exactly.
Is there a comprehensive website for driver download?

1) - You can just install an older driver, or,
2) - In Device Manager, right click the BT device, click Properties, and on the Driver tab click "Roll Back Driver". If it is grayed out as in the example below you can not roll back to a previous driver. In that case option one should work.



That said, I'm not sure going back to an older driver will solve the issue, but...

The roll Back Driver is gray.
What do I do? Isn't there a way?

I have suggested

a. You try the one for Windows 8.1 and I have given you a URL.
b. You search for one

Have you done either?


I have explained quite specifically that because you clean installed, you will have received a driver then. There will be no roll-back option unless there was then an update to that driver- which would be unlikely. Because there has been no update, there is only one driver in question. Therefore there is no driver to roll back to.

All this is repetition of what has been said before. Hope that's now clear.

I prefer to buy a Bluetooth dongle instead of installing windows 8.1

dalchina said:

No, I don't mean installing 8.1 and never suggested that - you use the driver that is listed as compatible with and available for Windows 8.1- which has a good chance of still working in Win 10. I.e. an older driver. You may be able to do some research and find a later one from the manufacturer of the device.

I gave you the link from your manufacturer a long time back...

God bless you bro.
I installed that and my problem is solve now.
Thank you so much
