[ath9k-devel] AR9287 ; 2-wire coexistence expected behavior

[sandeep suresh <sandeep.suresh@yahoo.co.in>]

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

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!)
