[ath9k-devel] bluetooth does not work (AR9485).

[Yevgeniy Melnichuk]

Hi everybody,

my notebook is equipped with a AR9485. Wireless LAN works flawlessly, but
bluetooth does not. Scanning shows no devices although my smartphone should
be visible. A second notebook equipped with a intel chip finds the
smartphone. Other way around does not work either. I configure the notebook
with AR9485 to be visible, but it does not show up on my smartphone. Again,
with the other notebook it works.

i have found people with similar problems:
https://answers.launchpad.net/ubuntu/+source/bluez/+question/186364
but i did not found a solution.

the problem is there with kernel 3.2.4 and 3.5.0

am i doing something wrong or is it a (known?) bug.

Thx in advance,
Yevgeniy

I have never used bluetooth before, so i am not sure, where to look for the
information, you ask me for.
How can i tell what firmware i am using?

here is some information, that may help.

    i enable bluetooth with the bluetooth-applet in unity.
    i check with "rfkill list" whether everything is unblocked
    i run bluetooth-wizard from gnome-bluetooth package and start scanning

is this informtion sufficient?

please follow the procedure mentioned in the link
http://wireless.kernel.org/en/users/Drivers/ath3k

if its AR3012 you need to create a dir
like
/lib/firmware/ar3k/
and then put those dfu
For AR3012, you can find the "AthrBT_0x01020200.dfu" and
"ramps_0x01020200_26.dfu" or "ramps_0x01020200_40.dfu" on the
linux-firmware git tree:

[ath9k-devel] bluetooth does not work (AR9485).

[Yevgeniy Melnichuk]

Hi Mohammed,

thx again for the answer.
My mistake was to think AR9485 is responsible for wireless and bluetooth.

i followed the instructions on
http://wireless.kernel.org/en/users/Drivers/ath3k
According to the instructions it is a AR3012.
i had to patch ath3k.c and btusb.c and add my device to the
support/blacklist list.
i copied ar3k folder from the kernel gitr-repository to /lib.
Now i get the following error when loading ath3k:
Bluetooth: Error in firmware loading err = -110,len = 0, size = 4096

what does it mean?

Bye,
Yevgeniy

awesome!  just now figured out for 3012 devices we have to add VID/PID
some thing like this
http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/00062.html

Please send a public patch for this
for bluetooth you will want to send them to Marcel Holtmann and cc the
linux-bluetooth mailing list, maintainers of ath3k
and cc me to0.
i think you go to see the following maintainer too
Gustavo Padovan <gustavo@padovan.org>

pls let me know if you need any help

[ath9k-devel] bluetooth does not work (AR9485).

[Mohammed Shafi]

Hi,

ensure if you are using WLAN + BT, make sure you enable BTCOEX in
.config and as a module param
http://linuxwireless.org/en/users/Drivers/ath9k/btcoex

[ath9k-devel] bluetooth does not work (AR9485).

hi Mohammed,

CONFIG_ATH9K_BTCOEX_SUPPORT is set to Y and it looks like btcoex_enable is
enabled by default, because wlan+bt work together without me changing any
module-parameters.

no . i think you got to do sudo modprobe -v ath9k btcoex_enable=1
this ensures smooth coexistence between wifi and BTcoex..
other wise its a bug!
