I changed the weight register to reflect the weightage of BT (= 0xFFFF) and WLAN(= 0x0000) ?which was verified after dumping the registers. I will try changing the mode and inform the results. What exactly is the meaning of these modes: a) Legacy rx_clear mode b) Untimed/unslotted mode c) Slotted mode? ? Thanks & regards Sandeep Suresh. ________________________________ From: Adrian Chadd To: sandeep suresh Cc: Sujith Manoharan ; ath9k-devel ; "linux-wireless at vger.kernel.org" Sent: Tuesday, 16 April 2013 10:30 PM Subject: Re: [ath9k-devel] AR9287 ; 2-wire coexistence expected behavior On 15 April 2013 20:55, sandeep suresh wrote: > Hello Mr.Adrian, >? ?

You want 2-wire / legacy rx_clear mode for the _MODE_ field inside AR_BT_COEX_MODE. > ar5416phy.h:#define? ? AR_BT_COEX_WEIGHT? ? ? ? ? 0x8174? ? ? Value is: > 0xa8a8ff55 Double-check your weight values and make sure that they're actually -correct- for having BT stomp wifi in all instances.
