Ok, what about

sudo rfkill list

? If you see any tooths listed, run

sudo rfkill unblock bluetooth

Either way, run:

sudo systemctl enable bluetooth

Then log out and in - test if you can connect Bluetoof

#17

still no go :frowning:

do you think this line in the results i got from the command earlier might be the issue?

Yes, that would do it... Somehow I missed seeing that earlier...
Try downloading this patch:

Look toward the portion beneath "history" to see a Download button. Hit that.

Then open terminal and run:
sudo cp BCM43142A0-0a5c-21d7.hcd /lib/firmware/brcm/BCM43142A0-0a5c-21d7.hcd

sudo modprobe -r btusb

sudo modprobe btusb

#19

cp: cannot stat 'BCM43142A0-0a5c-21d7.hcd': No such file or directory

#20

Yes, lol. It's almost 11pm here... Second time in one thread I did not notice a detail.

#22

no worries. Thank you for helping. should i change both file names? cause its returning a command not found error

#23

Ok I just downloaded the file to be sure:

sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd

You may need to run it from your Downloads folder. Open terminal, then Change Directory to Downloads

cd ~/Downloads

Then

sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd

sudo modprobe -r btusb

sudo modprobe btus

lee@lee-HP:~/Downloads$ sudo modprobe -r btusb
lee@lee-HP:~/Downloads$ sudo modprobe btus
modprobe: FATAL: Module btus not found in directory /lib/modules/5.4.0-80-generic

#25

Can you run

sudo depmod

then try to modprobe btus again?

#26

still got that error :frowning:

lee@lee-HP:~/Downloads$ sudo depmod
lee@lee-HP:~/Downloads$ sudo modprobe btus
modprobe: FATAL: Module btus not found in directory /lib/modules/5.4.0-80-generic

#27

That is strange... I am running Zorin 16 with Kernel 5.11 and it shows up in my system.
Try:

sudo apt-get install -y linux-modules-extra-5.4.0-80-generic

Relay the output and if successful, log out and in, test Bluetooth...

should i still do this again?

#32

Nah... If it's working, it's working. Not sure why the modprode error, but... Why question fate (unless you don't like the fate dealt)?

Hey, @LeeYael28 You are not the only one who have this kind of annoying thing. I am also a laptop user and found lack of driver support for a Laptop.

If you ask me I would recommend you to buy a new Bluetooth Dongle or if you already have then go with dongle. Cause Laptop Bluetooth adapter is not detectable for Linux PC. I am using a Dual Boot of Windows 10 and Zorin OS. But in windows 10 it's completely working (Bluetooth Adapter).

Don't worry you don't have to switch on any other Linux because none of them will help you at all.

But if you really want to use your Bluetooth of your Laptop. I have a solution of that.. But might be hard to switch to that OS..

Yeah, It's Manjaro KDE Edition. I don't know why but there I found my Bluetooth to be searchable even if I was not using Bluetooth Dongle.

And also I used it to connect my headset.

Hope You Got The Thing What You Are Actually Looking For.. :slight_smile:
