[Bug 1311289] Re: 168c:0032 [TravelMate B113-E] Has issues with bluetooth


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.
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

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
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...

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

Status in linux package in Ubuntu:

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.
  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.
