Ubuntu doesn't have driver for Broadcom BCM43142 Bluetooth Adapter

[Igor Zubarev]

Hello!

I have laptop Sony VAIO SVF15A1S9R with Ubuntu 19.10. Unfortunately my bluetooth doesn't work.
I digged some info and found that driver for my Broadcom BCM43142 Bluetooth Adapter does't exist in /lib/firmware/brcm. Please fix it. See my output:

find /lib/firmware/brcm -name '*4314*'
/lib/firmware/brcm/brcmfmac43143.bin
/lib/firmware/brcm/brcmfmac43143-sdio.bin

Hi,
can you try to install the proprietary driver from "software and updates" (if available)
Thanks

[Kai-Heng Feng (kaihengfeng)]

The firmware is proprietary so Ubuntu can't ship it.

This can be an alternative:

Hello.

It seems I solved my problem by typing in terminal:

$ sudo apt install firmware-b43-installer

[Igor Zubarev (igor.zubarev)]

Before it I already installed the proprietary driver from "software and updates" and it helped for Wi-Fi only, not Bluetooth

My Problem was just a naming issue :-

$ dmesg | grep -i 'bluetooth'

if you are facing some naming problem,the output of above command should be somthing like this ->

Bluetooth hci0: Direct firmware load for brcm/BCM43142A0-0489-e062.hcd failed with error -2
Bluetooth: hci0: BCM: Patch brcm/BCM43142A0-0489-e062.hcd not found

The Problem here is in this folder : /lib/firmware/brcm

$ ls /lib/firmware/brcm/*.hcd

The above command gives output of some *.hcd file (in my case BCM.hcd).
But my kernal is looking for BCM43142A0-0489-e062.hcd.
All you need to do is make a copy and rename.

$ cp /lib/firmware/brcm/BCM.hcd /lib/firmware/brcm/BCM43142A0-0489-e062.hcd (in my case)

Restart the PC and will see the frimware is loaded.

BAM!!
Now you can see bluetooh is working.
Done.
