Sure Mr. Adrian...that will be of great help.
As AR9287 supports both 2-wire and 3-wire, we thought 3-wire can be used.

Sandeep.

Subject: Re: AR9287; BT Coexistence with 3-wire
I'll have to check this tomorrow.
It depends on what kind of BT chip was put on the AR9287 combo board
that you have. And I don't know whether it uses 2 wire or 3 wire.
There's a whole bunch of functions in the reference driver HAL which
tune the BT coexistence parameters. I'll see if I can dig that up too.
