Can developers add a switch for bluetooth coexistence?

The problem is that when it's on my bluetooth mouse laggs, but when
I'm insulating the coexistance system pins it works just perfect.

Strange, on http://linuxwireless.org/en/users/Drivers/b43 it says that
"Bluetooth coexistence protection" works.

What do you mean by "insulating the coexistance system pins"? Are
physically changing the connections on your board?

The problem is that I need to turn the coexistence off. I'm using a
piece of paper to prevent coexistence pins from contacting.

I think that loading b43 with 'modprobe b43 btcoex=0' should do what you want.
Have you tried that?

It doesn't work for me.

Did you unload it first? AFAICT, that option should do the same as you are doing
with your piece of paper. If not, you will have to debug it. I don't have the
hardware.

Yes, I unloaded it and rebooted a few times, trying other switches
like hwpctl and their combinations. What kind of debugging output do
you want me to get? But I'm somehow confident that this may not be a
bad hardware problem as "ifconfig wlan1 down" allows my bluetooth
devices to operate normally. And as I can understand ifconfig down
doesn't perform a normal hardware power off.

I successfully replace my piece of paper with "echo on
>/sys/class/bluetooth/hci0/power/control" It looks that the problem
was broken power management.
