Bug Description

I am using an Acer E 15. I am not sure how to find out the specifications of my bluetooth device. I found nothing with lsusb or lspci. The only thing i found was that:

dmesg | grep bluetooth
[ 12.314809] bluetooth hci0: Direct firmware load for brcm/BCM43142A0-04ca-2009.hcd failed with error -2

Until Ubuntu 14.10 the bluetooth device was not recognized at all. Since the update to Ubuntu 15.04 i can activate it through Gnome system settings and make it visible. But it will not be found by any device and will not find any itself.

Unfortunatly acer does not offer a BIOS Update image, only a Bios update windows application (exe). The support only tells me that they don't support linux even though I don't need Linux support but only the bios update image!

Would it be possible for you to test the latest upstream kernel? Refer to . Please test the latest v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This bug exists because firmware brcm/BCM43142A0-04ca-2009.hcd is not found in Ubuntu. Please add it.

Amr Ibrahim is right. I downloaded the missing file from and renamed it to /lib/firmware/brcm/BCM.hcd. Now bluetooth works fine. Can't this file be added to Ubuntu so that not everyone needs to do this manually? Or is it a licence issue?

Btw, this seems to be a duplicate of

Unless Broadcom release its bluetooth firmware with compatible license with linux-firmware, we can't do much here.

summary: - Bluetooth doesn't find any device
+ Bluetooth firmware missing for BCM43142A0-04ca-2009

Kai-Heng Feng, as per Broadcom, they provide firmware via Windows update:

Hence, why not have a package in Ubuntu that scripts pulling the relevant file from Windows update, extracts the relevant bits, and moves it into the proper location?

This is nothing more than automating what folks already do to WORKAROUND this issue, without forcing everyone to hold their breath waiting for a license from Broadcom.
