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:

Adding visibility to @carkrueger 's comment below

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.

Hi all!

I'm use BT 5.0 adapter with HWID USB\VID_0BDA&PID_8771&REV_0200 (RTL 8761b?) on Windows 8.1
I'm tried many diferent versions of drivers (including downloaded by Windows) and all have one problem - Play/Pause button don't work normal nowhere except Windows Media Player. AIMP, Chrome (Youtub) react on Next/Previous Track only but not on Play/Pause. I tried on 2 headphones: Mi True Wireless EBs Basic S and Defender FreeMotion B525.

May be somebody know how to fix it or it driver bug and unsolvable?

Thanks

I've been using the Asus USB-BT500 driver with success in Windows 10. I think it is worth a try.

https://drive.google.com/file/d/1G_CX27WlVNIp70uMs0_QUeYDRGOrSgDT/view?usp=sharing

been using this driver with good luck so far.

If anyone can help it's appreciated.

I have a Mpow BH456A Bluetooth adapter listed RTL8671B.

I tried almost everything but after installation from Win 10 to Win 11 this device not work.
I tried a lot of different version drivers without success, old and newer.
I tried the last drivers in the last post too, but nothing.

The issue is: i can't find any bluetooth devices.

I know it's a driver issue, but how is it possible fix it??

Thanks a lot.

Yes i did them. All of them. I can't find any devices from my usb bluetooth adapter.

The issue is: i can't find any bluetooth devices.

In device manager: View -> Hidden Devices

In device manager: View -> Hidden Devices

Hi there, thank you for your reply.

Like you can see in the images attached I did it, and there are some hidden devices. I screenshoted one of the hidden device and it says error code 45 but is obvious i think. The other not hidden is recognixed without problem but... I can't find devices when i try to look for another bluetooth device to pair. Maybe i explained bad before.

I tried different driver versions, @bandit8623 too, but without success.

Update.

For windows 11 there is not drivers for my bluetooth adapter MPOW BH456A. It's sad. Thank you so much at all

Thank you; I think this version was less jittery than earlier ones, therefore improved experience .

For edimax bt 5 dongles: Windows will automatically install the edimax drivers but it connects and disconnects my headphones immediately. If i replace the firmware file in c:\windows with the one from the generic driver on the windows update site, it then works perfectly. Strangely if I install the generic driver, the same disconnection issue happens. So it needs a combination of the edimax driver with the updated firmware from the generic driver to work perfectly :)

I had the same issue and this solution worked like a charm.

For a TP-Link UB500 5.0 (usb\vid_2357&pid_0604):
I am currently using ASUS BT500 1.6.1015.3020 driver, with no problems. Hope this helps someone

That's the one I am using too. Never had a problem since installing it.

The firmware rtl8761b_mp_chip_bt40_fw_asic_rom_patch_new.dat included can probably also be installed in Linux as /lib/firmware/rtl_bt/rtl8761bu_fw.bin.* (after being compressed with xz or zstd or the like, to match your existing firmware distribution), and supply some of the same benefits there.

Whether or not a given VID/PID works out of the box on Linux depends on two factors, whether they've been added to the kernel, and whether the firmware is correct. This thread would seem to indicate there may be a problem with the 8761BU (USB) firmware that currently ships, which is from November of 2021: https://www.spinics.net/lists/linux-bluetooth/msg103399.html

I just wanted to say thanks for the driver...it's a little bit of kickass and it saved me a ton of searching time!

Cheers!

Here is the bluetooth 5.3 driver for our RTL8671b.
it has to be installed manually by force because the vid pid doesn't match. But everything works fine, I checked on 3 different bluetooths that have different vid pid but have the same RTL8671b chip.

You can give another link, this one doesn't work.

Thanks for the driver. Now device manager shows Realtek Bluetooth 5.3 Adapter and hci 12.56518 / lmp12.45992, my Easy Idea 5.0 adapter is based on Realtek RTL8761BUV chip, works now on 5.3 driver. However, it didn't solve my problem. I'm trying to launch the Anker Soundcore Note i (bt 5.2) headset, but there is still hope.

Sorry to read about it. I have Redmi Buds 3 Pro headphones, Edifer 820 NB+, Realme Buds T100, and they all work, at least on SBC (I didn’t check more specifically), since AAC and APTX support is only in the latest versions of Windows 10 and 11, and LDAC still not officially supported. If your headphones connect but do not play sound, there may be a problem with the codecs. All my headphones connected to bluetooth 5.0 - 5.3 working fine, I checked on different devices and different bluetooth dongles 5.x , maybe on lower versions, I did not check.
Or, may be your phones not support multipoint and first you must unpair it from one device to connect it to another

Sorry for my english and a lot of letters. In general, after checking in the store, it worked fine with a smartphone (headphones support sbc and aac).
I brought it home, I connect it to the PC, they are not visible. I installed the native Chinese driver 1.6.1015.3010 - it does not work. Turned off the smartphone and tried to connect the headphones - DEFINED AND CONNECTED. Then, after disconnecting, they did not connect again. There were separate attempts to connect, but not to the end. Further, it gets worse and worse, installing different drivers did not help. Now only headphones are detected, but not connected.
Everything else is connected to the PC - nokia 101, xiaomi phone and even smart watches(all delete). It remains to wait for the full discharge of the headphones and boxing, maybe that will work out. Or, in extreme cases, reinstalling the system (now it costs win10 21h2 enterprise LTSC with the latest updates)

Did you try unpair (not just disconnect) headphones from phone and then pair them to pc ?
Becose if headphones not support multipoint you can connect it only one device.
Did you try to do hard reset headphones and then connect to pc without connecting them to phone first?
In some case deleting headphones driver from windows including hidden drivers also can help.

Did you try unpair (not just disconnect) headphones from phone and then pair them to pc ?

Yes, I completely disconnected the headphones from the smartphone and deleted all the drivers, even turned off the phone. Of course I rebooted the box many times, deleted hidden devices in the manager, deleted all the drivers, different ways, only the driver from Microsoft remained. Most likely, something is broken in windows.

Yes, it can be. In some case only re-instaling windows can help.

Thank you for your concern and participation.
