Bluetooth on a Lenovo G500 stopped listing available connection results

Question

I installed Kubuntu on my Lenovo G500, and the Bluetooth didn't show any device results.

I had to install a bios update(3~4 days ago), so I connected a Windows 10 flashdrive (so i can execute an .exe file..) and on the way, tested the Bluetooth on windows 10 - and it worked!

After the bios update, I went to my Kubuntu, and the Bluetooth was listing available devices! I connected to my headphones and saved the connection, yey - I have no idea how it worked.

So, I decided to connect my headphones today again & wasn't managed to connect although the previous connection was saved and listed.

I decided to search for devices, and again - no bluetooth devices are listed.

Please help.

I have no "Bluetooth on/off" button on my keyboard as far as i know. Most posts mention the F5, But for my pc it's a refresh.
seems like i have Foxconn International, Inc. BCM43142A0 Bluetooth module bluetooth but i cannot find an install for it anywhere.
I tried doing things like disabling and enabling the bluetooth.
I tried resetting the bluetooth sudo service bluetooth restart & systemctl restart bluetooth.service

and did this too:

devwal@devwal-Len:~$ sudo rfkill list
[sudo] password for devwal: 
0: ideapad_wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: ideapad_bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
3: brcmwl-0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
5: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
devwal@devwal-Len:~$ sudo rfkill unblock bluetooth
devwal@devwal-Len:~$ sudo service bluetooth start

non of the above didn't resolve the problem. .

Ohhh after a few hours of googling, I have found the best solution for this kind of problem - one of the outputs of the command dmesg | grep -i bluetooth was:

[22.562560] Bluetooth: hci0: BCM: Patch brcm/BCM43142A0-105b-e065.hcd not found

the file just doesn't exist in the directory: /lib/firmware/brcm

Download the missing file from here.
Restart your machine.

and the Bluetooth should be up and running!

PS: i tried following this solution: https://github.com/jeremyb31/newbtfix-4.15 and it killed my wifi. do not recommend.

It should work without the github, looks like only firmware is needed – Jeremy31 Apr 08 '20 at 20:59

This saved a lot of time, works on Arch too. Thanks! – Uzumaki D. Ichigo Jul 06 '20 at 13:46

This solution helped me. Also this comment in Launchpad.net by TJ helped me identify exactly which hcd file I need to download from the github repo of winterheart. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743336/comments/3 – rineez Aug 09 '20 at 13:03
