Realtek bluetooth usb adapter RTL8671b

Readme.md

The CD that came with the device listed RTL8671B, but it's not on Realtek's website. Instead the manual points you to:

If you look here: https://www.catalog.update.microsoft.com/Search.aspx?q=realtek+bluetooth+1.6.1015 You will find now: 1.6.1015.3014 from 11.01.2021

Direct download link: http://download.windowsupdate.com/c/msdownload/update/driver/drvs/2021/02/0d13721d-7aa7-47cf-887a-f53bcd228a5e_04c173bad44cec04d528d260392958dc6e5bcec3.cab

Direct download and the popup window for 1.6.1015.3014 didn't initially work. I ended up needing to right click the link and select Save target as. For it to work for me on Windows 10, I unzipped the cab file into a folder and then used Device Manager to look at that folder. Worked like a charm.

https://www.catalog.update.microsoft.com/Search.aspx?q=Bluetooth%205.4%20driver%201.9.1051.3014 This is Bluetooth 5.4 driver for Realtek 8761b version: 1.9.1051.3014 HCI 12.56518 LMP 12.45992

It turns out that if you install the 5.4 drivers for version 5.3 , it should be a little better?

Thanks everyone, I successfully updated my drivers (on Win11) for this bluetooth dongle: mpow bh456a

Sadly, the seller is not responding to my mails, nor drivers are available on their website. I'm posting this so people can find it more easily.
