USB Bluettooth dongle on Linux Mint 20.3

Post by dbyy »

Hello,

recently my Bluettooth problem on my laptop got resolved through a forums posting.
Today I'm dealing with a different system. It's a custom build pc tower with ASUS Prime A320M-K MB and Ryzen 3 CPU.
This system AFAIK does not have a build-in bluettooth system. Therefore I'm using an Bluetooth 5.0 USB dongle but I can't connect my Bluettooth speakers.

I run the following query:

What Kernel are you running?

Quite possible that the dongle isn't supported under the kernel you have. Easy enough to try a newer kernel (e.g. 5.13).

I had similar bluetooth issues and I learned there are two types of chips used in bluetooth dongles. Broadcom and CSR (Cambridge Silicon Radio). I found the dongle that worked best in my Linux Mint was an ASUS BT400 which uses the Broadcom chip. It works flawlessly everytime connecting my Linux desktop pc with my Bose headphones and to my Android mobile phone. I also have a CSR dongle that I could not get working at all in Linux, but it did work in my old Windows pc which I no longer use. So there was nothing wrong with the CSR dongle itself, Linux just didn't like the CSR chip.

Edit: I use the 5.4 kernel, currently 5.4-0-105

-> Kendoori: my kernel is 5.4.0-105

and the Bluetooth dongle has a Realtek bluetooth chip

IMHO, I highly recommend upgrading your kernel to 5.13.x. Make a TimeShift snapshot just to be safe, and you can easily go back if you need/want to.

I just updated the kernel to 5.13.0.39 and tried to connect my Bluetooth speaker via USB dongle again. Failed again.
I guess I'm still missing the right drivers.

Any suggestions?
TIA

BT and Linux can be super finicky. For example, my internal Intel AX210 (a very modern card) did not work with the 5.4 kernel, does work with 5.13, but is flakey connectivity wise. I can confirm that this cheap USB dongle works very well: https://smile.amazon.com/gp/product/B00 ... UTF8&psc=1

This is an area where Windows is unfortunately better compatibility-wise.

Understood and certainly not suggesting you just throw money at it; however, being realistic you MAY not be able to fix it. Just a matter of how much time and energy you are willing to spend on it.

Hello dbyy,

it's obvious that the firmware file rtl_bt/rtl8761a_config.bin is missing, but I can't find it anywhere but only one rtl_bt/rtl8761b_config.bin. I've seen in the Linux Hardware Database, that the same dongle is using the rtl_bt/rtl8761b firmware files (search the dmesg): https://linux-hardware.org/?probe=4ae6eba2f6&log=dmesg

So I suggest, that you copy the rtl_bt/rtl8761b firmware files to /lib/firmware/rtl_bt. I attach both files in a zip-file. Please extraxt them in the Downloads folder and right-click on an empty space and choose open in terminal. Then run the following commands:

Code: Select all

sudo cp rtl8761b_fw.bin /lib/firmware/rtl_bt
sudo cp rtl8761b_config.bin /lib/firmware/rtl_bt
Then reboot, see if it changes something and show again

Code: Select all

dmesg | egrep -i 'blue|firm'

Good news.
After installing those drivers in the designated folder the Bluettooth is now recognizing and using the Bluettooth speakers.
Interestingly only after I moved the USB dongle form a USB hub (I used) to a base USB connector on the front panel.

I will later test the previous configuration (removing the drivers) but use the base USB connector.
I will post the results afterwards.

Thanks for the help.
It's much appreciated.

I completed the test and it appears that not the driver update resolved the problem but the move of the USB Bluetooth dongle form the USB hub to a base USB connector.

Don't blame the driver !!! hehe
Cheers to the experts.

Re: USB Bluettooth dongle on Linux Mint 20.3

I posted this thread a few month ago and it got resolved at that time.

Now a few month later and some updates of Linux mint since then, my Bluetooth is not working again.
Same speakers I was able to connect at that are not working anymore.
Is it possible that some OS updates broke the Bluetooth again?

I'll post the output of lsusb; dmesg | egrep 0i 'blue' below:
