168c:0032 [TravelMate B113-E] Has issues with bluetooth

[Wildman]

I have Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01) on Acer TM B113-E notebook.

When I use ath9k with 3.11 kernel then all works fine. WiFi and Bluetooth works as well.
I have problem with bluetooth when install some later kernels(I'm test 3.15rc1 and (3.13 or 3.14)) from http://kernel.ubuntu.com/~kernel-ppa/mainline/
After this installation I have not bluetooth device! When I switch Wi-Fi by acpi key, I can switch only Wi-Fi to on or off state(I saw status by "rfkill list"). Bluetooth device will not reconize for me...
But if I will power off notebook and disconnect battery, then after power on I'm get working Bluetooth.

I could not pay attention to this troubles but now we have Ubuntu 14.04(I tested on Kubuntu 14.04).
After installed Kubuntu 14.04 I have working only Wi-Fi. Power off+disconnect battery and other probes(such as I probe to install non-free firmware) do not have results. System do not recognize BT device... I can not see this device in rfkill list and in KDE's System Settings->Bluetooth...
In 3.11 kernel and later kernel I have problem with bluetooth after sleeping too. Module do not start after resume. I wrote script with manual starting of btusb module and get working BT after resume.

My bluetooth device as per sudo cat /sys/kernel/debug/usb/devices :

I'm tested Kubuntu 14.04 x64 with 3.11.10-03111008-generic, 3.13.0-24-generic, 3.15.0-031500rc2-lowlatency kernels now. And now stay on 3.15rc2.
Nothing changes. I think this is not kernel's problem. May be my BT device do not recognized because upstart-udev and systemd-udev psrts conflicts. How do you think?

Now I have this logs:
dmesg | grep -i blue
[ 5.530076] Bluetooth: Core ver 2.19
[ 5.530119] Bluetooth: HCI device and connection manager initialized
[ 5.530129] Bluetooth: HCI socket layer initialized

[ 5.568256] Bluetooth: RFCOMM socket layer initialized
[ 5.568265] Bluetooth: RFCOMM ver 1.11
And I can see nothing about device...(((

In 13.10 I must manualy use btusb(if it do not loaded after resume) module to work BT. Now this module do not used by default:
#lsmod | grep blue
bluetooth 465597 10 bnep,rfcomm
6lowpan_iphc 18968 1 bluetooth
# modprobe btusb
# lsmod | grep blue
bluetooth 465597 11 bnep,btusb,rfcomm
6lowpan_iphc 18968 1 bluetooth

But after manual module loading nothing changes...(((

[Wildman (sasha-mishchenko)]

I have good news for me with this device on 14.04.
It works at now. But this will start after some movings of notebook's hardware.
I changed Atheros chip to Ralink 3189 chip(this chip do not works with Wi-Fi on later kernels with NetworkManager, but BT was recognized). After this I returned Atheros chip to notebook and my BT device stay available in system. I don't know how to long it will be available, I do not reboot it now. If I will get news then I will post information...

[penalvch (penalvch)]

Wildman, the next step is to bisect from Saucy to Trusty, in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[Wildman (sasha-mishchenko)]

I aerly tested 3.11 kernel in 14.04 and BT did not work.
But from now I may be can not to truly test, because after inserting Ralink card I have working Atheros BT. If I will have troubles with BT in future then I test older kernels...
In old times when I install 14.04 then after restore 13.10, my BT do not work while I deattach my battery.
With 14.04 this method do not work and only after reinstall another card, I can see BT...

[penalvch (penalvch)]

Wildman, as per your Bug Description:
>"I have Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01) on Acer TM B113-E notebook.
When I use ath9k with 3.11 kernel then all works fine. WiFi and Bluetooth works as well."

Is this not actually the case?

[Wildman (sasha-mishchenko)]

Actualy.
Because after using BT mouse WiFi began drop packets and while I use inet conections interface sometimes drops and I must it enable manual...
After some testings I return to 13.10.
But when I return to 13.10, I get problems with wifi interface. It swith out after less 1 min after upping. And Kwallet asks me enter password of WIFI access point.

Problem persist and IMHO this is problem in behavior Ubuntu with ACPI.
I created a copy of installed 14.04 and will test it after left some time (near ones at month). I will report to this topic.

[penalvch (penalvch)]

Wildman, just to be clear, regarding the scope of this bug report "168c:0032 [TravelMate B113-E] Has issues with bluetooth", did bluetooth (not WiFi) work or not work in 13.10?

[Launchpad Janitor (janitor)]

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Wildman (sasha-mishchenko)]

This problem returns to my notebook again, when I upgrade to Kubuntu 16.04 with KDE5
In older systems I can use BT only if acer_wmi module was blacklisted
Now it can works only if this module enabled. ))) with blacklisted module I have no any solutions.
But...
1. After reboot I have only WiFi every time. After sleeping BT is lost too.

2. Sometimes if I switch to BT(WiFi) On or Off by ACPI key then BT drops and I can not see it by
rfkill list

3. After some switches by ACPI key 'rfkill list' shows me BT & WiFi is on, but WiFi do not work.

4. Only netbook's poweroff and unsupply battery helps me returns to 1 position.

5. Adter some switching by ACPI Key if BT switched to On, then rfkill list shows new idx of BT device:
At first time it shows like:
...
4: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

On new loop of switching it shows like:
...
5: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
...
etc
But BT do not work.

6. If I do not unsupply battery then I can not get working BT and WiFi in any way.

7. I probe to use systemd-rfkill.service but it did not helps me...

[Wildman (sasha-mishchenko)]

Have new small solution. With it I can work, but problem still present.
1. I need "blacklist acer_wmi" in modprobe.conf )))
2. I need "options ath9k btcoex_enable=1" in modprobe.conf
It works better then early. But I can not get WiFi after sleeping. But after reboot I get BT & WiFi working. This is better then nothing.
After sleeping rfkill says about all is on, but WiFi do not up...

[Wildman (sasha-mishchenko)]

I have upgradet kernel to 4.5.3 but this do not helps me...

[penalvch (penalvch)]

Wildman, could you please test the latest mainline kernel (4.7-rc2) and advise to the results?

[Wildman (sasha-mishchenko)]

I tested 4.6.0-rc7-willy kernel maximum. Situation are no changed. Kernel 4.6.1 for yakkety did not start on 16.04.((( I think 4.7rc2 did not start too. I tested it from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Will I test from kernel.org?

[Wildman (sasha-mishchenko)]

 I have some stability at now. ))
If I do not use wifi acpi key then I have Wi-Fi and BT after reboot or sleeping. If I began use it and reboot with BT off then after reboot I can not switch on BT(only WiFi on/off). Dometimes after using wifi key I can select BT & WiFi on, widgets on tray say me - those device is on, but BT do not work(can not connect to paired mouse, or WiFi is on but I can not see any ISSD near me and can not connect to one.
Adter this, in BIOS I have no BT device(!), Only WiFi. I think ACPI module send some information to hardware which switch off it and BIOS can not recognize BT HW...
Only poweroff and battery off saves me. After inserting battery I go to BIOS and can see BT device enabled.

[penalvch (penalvch)]

Wildman, if 4.7-rc2 doesn't allow you to test to this problem, please test successively older kernels until you have the most recent kernel possible allowing a test.

[Wildman (sasha-mishchenko)]

4.7.0rc2 kernel installed(taht's wndering me) but do not helps me too.
4.3.0 are not helps too.
3.16, 3.19(I used on 14.04 it, I used and newer kernels from 14.04 repository and all works fine) can not be installable (can not resolve dependences).
Is not problem in kernel? May be systemd or other functionality send wrong information to hardware and hardware hangs...
Now I am try to compile latest 3.18 from kernel.org.

[penalvch (penalvch)]

wildman, to advise, the mainline kernels are kernel.org kernels.

[Wildman (sasha-mishchenko)]

I know this, but packages on kernel.ubuntu.com has patches and dependences, which can not be used in 16.04...(((
I compile 3.18.35 and have no solution for my problem... ((( 3.16,3.18,3.19 had bad issue: my cursor was clear. It works but I see only onfocus doings.

Some situation(as this) was when I upgrade to 14.04. Which thing helps me I did not remember now. After this All new kernels and new upgrades works fine on 14.04.
If I find solution - I wrote to this feed...

[Wildman (sasha-mishchenko)]

Now I can not resolve this problem.
I use another Wi-Fi+BT card.

But may be my story will be usefull for future work with problem.
I have Acer TM B113-E which complected with Broadcom Corporation BCM43228 Wi-Fi+BT card.
With older kernels(3.11) it works fine. But when I began upgrade kernel, this card works unstable(with Cisco wi-fi routers I have a lot of broken connections, some times connection was droped on another routers too). I purchase Atheros AR9485 and successfully use it until have upgrade to 14.04.
With new OS I can not set up BT to work fine. I probe all methods, but nothing helps me.
If I remember, I put hands down and insert original BCM43228. I did not setup it too and reinsert AR9485. After this series of reinserting Atheros card began works fine!
I think Broadcom card may be wrote some information to BIOS ACPI (or other part of BIOS) and new card began work without troubles.

I probe this method now. But I can not resolve my problem by this manual.
Now I use Broadcom card, which works some stable, but has slow speed(near 1Mb/s). Atheros card had 2.5Mb/s speed on this router. After advanced setuping of my home router, I had increase of speed to 1.5-1.9Mb/s on it.
