I resumed my experiments with 2-wire co-existence with AR9287 in WiFi AP mode. I was able to see that WLAN_STATUS signal being suppressed when BT_ACTIVE is enabled. I used a 100ms On and 100ms Off (Period = 200ms; 50% dc) for BT_ACTIVE. Just want to confirm the following before ensuring that I am seeing the expected behavior: ? 1. As I am running the WiFi AP with co-existence, other WiFi clients are connected to my AP. by means of diagnsosis (I have enabled diagnosis with modprobe ath9k btcoex_enabled=1 diag=0xffffffff), how can I find out if any WiFi clients are loosing connection and re-connecting back to AP. ? 2. How can I come to know if any of the beacons in WiFi AP mode are getting missed? Diagnosis messages that I can look at. ? 3. As diagnosis is enabled I see the following....is this a concern as there is disable and enable of IER? <7>ath: disable IER <7>ath: AR_IMR 0x918104b0 IER 0x1 <7>ath: tx queue 2 (4bfc09c4), link ffde09c4 <7>ath: enable IER <7>ath: Enable TXE on queue: 2 <7>ath: disable IER <7>ath: AR_IMR 0x918104b0 IER 0x1 ? 4. How can I come to know if the ath9k drivers are getting reset and reinitializing? ? Thanks & Regards Sandeep Suresh. ________________________________ From: Adrian Chadd To: sandeep suresh Cc: ath9k-devel ; linux-wireless at vger.kernel.org Sent: Thursday, 18 April 2013 7:46 PM Subject: Re: [ath9k-devel] AR9287 ; 2-wire coexistence expected behavior On 18 April 2013 03:34, sandeep suresh wrote: > Hello Mr.Adrian, >? ?

If there's some strong signal in the air that exceeds the CCA threshold but isn't a decodable wifi signal, rx_clear is cleared.
