Hello Mr.Adrian,
Thanks for your mail. Request to share more information on this as and when
you discover, Please. As you mentioned below that BT code for coexistence is in
freeBSD, Can you please send me the link so that I can also start digging into
the code base and share to the community on my learnings? This will be a useful
effort.
Thanks & regards
Sandeep

Subject: Re: AR9287 ; 2-wire coexistence expected behavior
Hi!
So, I've just done some further digging.
Yes, AR9285/AR9287 (and AR9380 and later) all support 2-wire and
3-wire bluetooth coexistence.
So I am gathering that the ath9k bluetooth setup code has to mostly do with:
* whether the particular combo wlan NIC has two or three wire
bluetooth coexistence wired up;
* the platform specifics about how to program the MAC bluetooth registers;
* .. and some ancillary stuff like antenna diversity on the AR9285.
I'll have to sit down with an WB195 (AR9285 + BT) and WB197 (AR9287 +
BT) to actually see how the various BT register and GPIO mux
programming works. But the code is there in freebsd and ath9k; it's
just not well documented (yet!)
Adrian
