Qualcomm Atheros Bluetooth 4.0 (04CA 3014) is not detected

vinyanalista · April 21, 2017, 5:26pm

I have an Acer Aspire E15 laptop (model number E5-573-54ZV) that came with Windows 10 and a built-in Bluetooth 4.0 adapter. While using Windows, I’m able to use the Bluetooth adapter.

I’ve installed openSUSE Leap 42.2 in dual boot. While using openSUSE, the Bluetooth adapter is the only piece of hardware that does not work. It seems like it is not even detected.

A report made using AIDA64 for Windows shows:

04CA 3014    Qualcomm Atheros Bluetooth 4.0

It appears in the USB devices section, so it is attached to the USB bus.

Someone made it work on Linux Mint: https://forums.linuxmint.com/viewtopic.php?t=217091

How can I make that Bluetooth adapter work on openSUSE?

Thank you in advance!

Some commands and their outputs:

Some notes about my USB devices:

Microsoft Corp. Nano Transceiver v1.0 for Bluetooth (045e:0745) is the transceiver for my Microsoft Wireless Desktop 800 (wireless keyboard + mouse combo). I use it at home.
I also have a third network adapter, TP-Link Archer T4U, which is a wireless dual band (802.11n/ac 2.4GHz/5GHz) USB adapter, I didn’t find it in the above outputs, I have installed it following the instructions here and here, if I run ifconfig it shows as wlan1

What I have tried so far…

Googling, I have found this kernel patch: https://patchwork.kernel.org/patch/8789671/

If I have understood that page correctly, it has been applied upstream to the kernel 4.5 release.

As openSUSE Leap 42.2 uses kernel 4.4.x, I installed the latest kernel release available from:

http://download.opensuse.org/repositories/Kernel:/stable/standard

Today, 4.10.11, as you can see in the uname output. Doing that didn’t make the Bluetooth adapter work.

Is Bluetooth blocked:

/usr/sbin/rfkill list all

That is the TP-Link:

Bus 001 Device 004: ID 2357:010d

vinyanalista · April 21, 2017, 7:39pm

I think it is not:


# /usr/sbin/rfkill list all
0: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: phy1: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Are phy0 and phy1 equivalent to wlan0 and wlan1? What is this acer-wireless?

That is the TP-Link:

Bus 001 Device 004: ID 2357:010d

Hmm now I see:

You are right, because rtl8812au is the name of the driver. Thank you!

Please post:

/sbin/lspci -nnk | grep -iA3 net

to see the ID and the Driver.

Thank you for the directions. I’ve read the section Bluetooth can’t find any devices and followed its instructions. Let me quote them here.

Some laptops have an Atheros AR9565 Wifi/Bluetooth controller built in:

# lsusb
...
Bus 001 Device 005: ID 04ca:3014 Lite-On Technology Corp. Qualcoom Atheros Bluetooth
...

Wifi works fine, the bluetooth controller is recognized but no bluetooth devices are found. The problem is that as of Linux 4.3.3 this devices is not listed in ath9k.ko which loads the firmware files and patches into the Atheros bluetooth controllers.

Indeed, my laptop has that controller. But it’s important to note that, in my case, that controller is not even recognized, as lsusb does not show it. Going on…

Quick and dirty fix, patching this USB ID into the modules (from: [Solved]Upgrade to kernel 3.15.1 causes bluetooth to fail / Kernel & Hardware / Arch Linux Forums):

Here is what I did (from [Solved]Upgrade to kernel 3.15.1 causes bluetooth to fail / Kernel & Hardware / Arch Linux Forums):


# cd /lib/modules/`uname -r`/kernel/drivers/bluetooth/
# cp ath3k.ko ath3k.ko.backup
# cp btusb.ko btusb.ko.backup
# sed -e 's/\xf3\x0c\x05\x30/\xf3\x0c\x05\xe0/g' ath3k.ko > at.ko
# sed -e 's/\xf3\x0c\x05\x30/\xf3\x0c\x05\xe0/g' btusb.ko > bt.ko
# mv at.ko ath3k.ko
# mv bt.ko btusb.ko
# rmmod ath3k
# rmmod btusb
# modprobe btusb
# modprobe ath3k

You will still need to copy two firmware files (AthrBT_0x31010100.dfu and ramps_0x31010100_40.dfu) under /lib/firmware/ar3k.

Curiously, they seem to be already there:

After following all the procedure until the end, lsusb still does not show my Bluetooth adapter. I’m going to reboot my laptop to see if anything changes.

vinyanalista · April 22, 2017, 3:38pm

Nothing changed…

I see the Kernel:stable OBS repo released a new kernel, version 4.10.12. I’m not going to install it because that would require me to repeat everything (install the driver for TP-Link Archer T4U, install the kernel modules for VMware Workstation Player and follow the procedure described on Bluetooth can’t find any devices).

I’m going to stay with the kernel 4.10.11-vanilla for a while:

# uname -a
Linux viny-notebook 4.10.11-1.gbd70196-vanilla #1 SMP PREEMPT Tue Apr 18 05:55:31 UTC 2017 (bd70196) x86_64 x86_64 x86_64 GNU/Linux

What should I try next?

Sauerland · April 22, 2017, 4:39pm

Linux viny-notebook 4.10.11-1.gbd70196-vanilla

Vanilla Kernel is without any Suse Patches, maybe the kernel-default do work??

vinyanalista · April 23, 2017, 3:11pm

Linux kernel 4.4.57 from openSUSE Leap 42.2 was still installed, so I rebooted with it:

# uname -a
Linux viny-notebook 4.4.57-18.3-default #1 SMP Thu Mar 30 06:39:47 UTC 2017 (39c8557) x86_64 x86_64 x86_64 GNU/Linux

TP-Link and VMware worked at first, I had to do nothing about them, but Bluetooth didn’t show up. I repeated the procedure described on Bluetooth can’t find any devices, nothing new. Then I rebooted, nothing new again.

I realized that there are modules for each kernel version (/lib/modules/uname -r/), but only one firmware for the whole system (/lib/firmware/). Right now, I’m using the package kernel-firmware from the Kernel:stable OBS repo. Should I downgrade it to the one provided by the openSUSE Leap 42.2 Update repo?

vinyanalista · April 23, 2017, 3:52pm

Later, I realized the Kernel:stable OBS repo also has a kernel-default package, so I installed it. I also made a clean up here, so now I have just 2 kernels installed (both kernel-default and their respective kernel-default-devel, kernel-devel, kernel-source, kernel-syms):

4.4.57 from the openSUSE Leap 42.2 Update repo; and
4.10.12 from the Kernel:stable repo.

Now I booted with the second one:


# uname -a
Linux viny-notebook 4.10.12-1.g3043bd9-default #1 SMP PREEMPT Fri Apr 21 11:50:25 UTC 2017 (3043bd9) x86_64 x86_64 x86_64 GNU/Linux

I managed to install the driver for TP-Link Archer T4U and the kernel modules for VMware Workstation Player.

The same happened this time with the 4.10.12-default kernel.

vinyanalista · May 20, 2017, 11:27pm

Now I’m just with the kernel 4.4.62 from the Leap 42.2 OSS repo:

# uname -a
Linux viny-notebook 4.4.62-18.6-default #1 SMP Fri Apr 21 16:14:48 UTC 2017 (84f9824) x86_64 x86_64 x86_64 GNU/Linux

I removed all the other kernels. Also, I downgraded everything (including kernel-firmware) to the Leap 42.2 OSS/Update repo.

I noticed a package named bluez-firmware, but installing it didn’t help recognizing my Bluetooth card.

I remembered I have an old and cheap Bluetooth 2.0 USB 2.0 dongle by Noteship. Just as a test, I decided to plug it on my laptop, not sure that test can help. The Bluetooth dongle was recognized and I was able to transfer a file using it. I was not able to stream to a Bluetooth speaker, but I think it’s a limitation of that dongle, as I was not able to stream audio on Windows as well.

Running those commands again, I got:

(as here)

Now I noticed: what happened to Bus 002 Device 003 on lsusb? It seems it was “skipped”. Maybe that’s the Bluetooth adapter we are looking for?

vinyanalista · June 7, 2017, 5:50am

Also, I downloaded the Windows driver for the Bluetooth adapter from the laptop manufacturer’s website: https://www.acer.com/drivers

I noticed it has the files AthrBT_0x31010100.dfu and ramps_0x31010100_40.dfu and the first differ in size from the one at /lib/firmware/ar3k/. So I replaced it and rebooted my laptop. Nothing happened.

Do you have any other idea that may help? I’m thinking about reporting a bug for the Linux kernel. By what I read on the Internet, that Bluetooth adapter should be at least recognized.

Yes, but in my case, my Bluetooth adapter is not even shown:

Now, I realized this:

The system somehow recognizes my Bluetooth adapter. Why it is not set up?

Googling around, I found this: bluetooth controller not showing up in lsusb but showing up in dmesg

What does dmesg mean by found and then disconnect???

vinyanalista · June 9, 2017, 4:17am

I thought: maybe the kernel finds the device, does not know how to handle it and then disconnect it. So, I decided to try to load the btusb and ath3k kernel modules earlier, right at boot time, using initramfs. I followed the instructions here:

Booting a Linux System | Reference | openSUSE Leap 42.2

echo ‘force_drivers+=“ath3k btusb”’ > /etc/dracut.conf.d/01-bluetooth.conf

dracut -f

reboot

Indeed, something has changed, new messages appeared in dmesg:

That is kernel 4.4.70 from the openSUSE Leap 42.2 Update repo, I’m going to try kernel 4.11.4 from the Kernel:stable OBS repo.

vinyanalista · June 9, 2017, 4:26am

Sorry, I misunderstood you! But I think that hci0 was an external USB dongle I had plugged in just as a test:

vinyanalista:

I remembered I have an old and cheap Bluetooth 2.0 USB 2.0 dongle by Noteship. Just as a test, I decided to plug it on my laptop, not sure that test can help. The Bluetooth dongle was recognized and I was able to transfer a file using it. I was not able to stream to a Bluetooth speaker, but I think it’s a limitation of that dongle, as I was not able to stream audio on Windows as well.

Running those commands again, I got:

…
# /usr/sbin/rfkill list all

3: hci0: Bluetooth

    Hard blocked: no
Those last three lines are new.

I already removed that dongle. Now I’m just with my Bluetooth card, which I’m trying to get recognized by the kernel.
