Bluetooth not working on Ubuntu - Sony Vaio Laptop

Question

This is my first question here on askubuntu.com.

I am an absolute beginner and installed ubuntu dual boot with windows 10. At first, the bluetooth on ubuntu didn't work for some reason, and I did a google search and just did that (mostly askubuntu or quora) and it worked!

Then, bluetooth on my windows 10 stopped working. I tried to install a driver for that but it still didn't work. When I came back to ubuntu, even bluetooth here doesn't work.

Bluetooth Module: BCM43142A0 Broadcom bluetooth adapter

EDIT: demsg shows a bluetooth error

hci0: BCM: Patch brcm/BCM43142A0-0489-e062.hcd not found
[  990.110777] audit: type=1400 audit(1607238711.750:120): apparmor="DENIED" operation="connect" profile="snap.bluez.bluetoothctl" name="/run/dbus/system_bus_socket" pid=7452 comm="bluetoothctl" requested_mask="wr" denied_mask="wr" fsuid=0 ouid=0
[ 1230.006319] Bluetooth: hci0: command 0x1003 tx timeout

I saw somewhere that we will have to manually download and put the .hcd file. I did so, but didn't help.

Can somebody please help me with this?

Does this answer your question? Bluetooth Broadcom 43142 isn't working — Pilot6, Dec 06 '20 at 07:45
No it doesn't. Thanks by the way. I forgot to mention that I tried everything on google. — Abhinav, Dec 06 '20 at 08:09
If you still have brcm/BCM43142A0-0489-e062.hcd not found, then you didn't follow the answer properly. You should have this file. — Pilot6, Dec 06 '20 at 08:28
oh. I too thought the same at first and retried it. But still the same — Abhinav, Dec 06 '20 at 11:43
What do you mean by "still the same". Are you having the same error? Is the file there? — Pilot6, Dec 06 '20 at 12:15

Undo whatever you did on Ubuntu.

Ubuntu is basically missing the bluetooth driver for Broadcom and that's all I think.

Download broadcom-bt-firmware
install it by using:

sudo apt install ./<package-name>.deb

OR

sudo apt install gdebi
sudo gdebi <package-name>.deb

I would recommend using gdebi as it will automatically install all the dependencies too. Although there are no dependencies for the above package but still it is a good practice to use gdebi.

Restart.

There are no dependencies ;-) So there is no need to use gdebi. – Pilot6 Dec 06 '20 at 09:05
I know but it is a good practice to use gdebi. – Mansoor Ahmed Memon Dec 06 '20 at 09:07
Thank you everyone for this, I'll try this and let you know :) – Abhinav Dec 06 '20 at 11:55
It is not a "good practice" to use gdebi. Now apt can install dependencies locally. There is no need in gdebi at all. – Pilot6 Dec 06 '20 at 12:34
Use whatever you want to but, I prefer gdebi. – Mansoor Ahmed Memon Dec 06 '20 at 12:47
Really, I wanna thank you guys a lot! – Abhinav Dec 06 '20 at 13:14
You helped me setup my bluetooth so easily! Thanks a lot. I would be happy to help you in any other way! Please let me know! :) – Abhinav Dec 06 '20 at 13:15
