Right. So we agree your patch should be applied by default to ath9k.
Just as coexistence is enabled by default for Intel wifi. Unless someone
more familiar with ath9k has a (better) reason otherwise...
** Summary changed:
- Enable Bluetooth-Wifi coexistence by default [bluetooth audio and
The user won't probably want to do that:
- The new default reduces the Wifi Speed only while bluetooth is actually
trying to send (which isn't too often if the user isn't currently listening to
Bluetooth audio) and
- If Bluetooth/Wifi coecistence isn't enabled Bluetooth (when trying to send
We should indeed default to the configuration that is reliable. And if
people want to switch to the less reliable, but faster, option then they
still can.

Kai,
I don't have the ath9k hardware, but it sounds like that's a necessary
evil... For Bluetooth users, halving the wifi speed is better than
unreliable Bluetooth.

I'm using the mainline build right now - and I still need to module
parameter in order to have more than 1 minute of bluetooth audio at a
time => We should send this patch.

Daniel,
IIRC, on ath9k WiFi speed drops to halve once BT coexistence is enabled.
Can you try if this is still the case?
If not, we should send a patch to enable it as default.

That probably won't help. The link in comment #5 seems to show the ath9k
source in Linus' tree is still defaulting to btcoex_enable=0
bt_ant_diversity=0.
At least I assume and hope uninitialized static variables in the kernel
means they're reliably zero...?

Please keep this bug about fixing the issue for ath9k wifi only.
So this bug is not a duplicate of bug 405294. This bug is open and
should be fixed in the kernel (package "linux").

I currently run the newest vanilla kernel using an Acer Aspire S7 with
an Intel chipset. Still my patch is needed on my system.

I have no experience in getting things changed in the kernel =>

Also, if all you would like to change is kernel parameters:
options ath9k btcoex_enable=1 bt_ant_diversity=1
then that's a kernel bug/enhancement. Not something that bluez should be
involved in...
It appears those two parameters are uninitialized by default (so default
to zero/off??):
Interestingly, it appears Intel enables bt_coex for their chips by
default:

Thanks for the suggestion. It sounds like this may fix bug 405294 for
some users.
Unfortunately you forgot to attach "bluetooth-audio.conf" mentioned in
your patch.
