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.

The newer file, that is ~720 bytes smaller, doesn't seem to be bt 5.4 any more.

TP-Link has file version 1.9.1051.3016 with same hash as 3015.
