Hi! I have been using Kubuntu as mi principal operative system on my personal notebook for more than a year. I never had any kind of problems, but recently, I bought an SSD and installed Kubuntu 20 (I used to have Kubuntu18). When I dissassembled the computer, I found out that the network adapter was a BCM943142HM card. Apparently, it also has bluettoth, and I wanted to know how to use it. When i try to scan bluetooth devices from my pc, nothing happens, as if the bluetooth wasn't working. I have tried with bluetoothctl, in konsole, but it seems that the real problem is that the drivers for bluetooth are not installed. I checked for the wi-fi drivers, the preinstalled are for a BCM43142, and they work just fine, but i have not found the drivers for the whole module (with bluetooth included). Can someone help me solve this issue? Or maybe I just can't use the bluetooth? Any help would be thankfully accepted, but if not, I would want to know where to ask for a solution. Thanks!

Assuming you talk about Kubuntu 20.04? The part after the dot is important...

Is the controller actually seen when you run lspci in the konsole?

Hi, thanks for replying. Yes, I'm sorry, I was talking about Kubuntu 20.04. KDE Plasma version is 5.18.5 and KDE Frameworks version is 5.68.0. Also Kernel version is 5.4.0-52-generic. This is what i get running "lspci" and also "dmesg | grep -i blue" (apparently this should say something about bluetooth and drivers). The drivers look as they are for a BCM43142 model. https://ibb.co/D5g57SZ

it apparently tries to load a driver but can't find it (error code -2), did you check the manufacturers support pages?

Yes, I did, but i couldn't find anything. The only results were some drivers for Windows, but nothing for Linux. This is a photo of the board: https://ibb.co/z8N5dRG

Do you have the general Broadcom driver installed? The package should be called bcmwl-kernel-source. Once this is installed, restart your computer and see if that helped.

Yes, I have those drivers already installed. I tried in konsole and in there it said that i already had them, and also recommended to run "apt-autoremove" to remove some unnecessary packages. I did that, rebooted but nothing seems to work.

Then I am really at loss here.

FWIW: please do not check the "Accept this answer" box, else the topic is marked as solved
