So I only have some advices for you.1. Video needs more throughput, so 7:3 or 8:2 seams better.2. If you use RTSP to transmit video, I guess you can short the switch time to reduce the delay. Just try to set period to 100ms or less for test. I think it will be better. > Date: Fri, 4 Apr 2014 09:55:40 +0800 > From: sandeep.sur...@yahoo.co.in > To: adr...@freebsd.org; ath9k-devel@lists.ath9k.org; linux-wirel...@vger.kernel.org > Subject: [ath9k-devel] Wifi client Bluetooth coexistence; non smooth video streams > > Dear all, > Please help if any one have encountered simillar problems or other guidance on this, Please. > > The following is my set-up: > Linksys Access point. Cisco 802.11g camera connected as a wifi client to Linksys. I have a development board in which i have AR9287 as the Wifi chipset associated as wifi client to linksys. The development board has Bluetooth dongle for streaming audio etc. The development board has a LCD display and I stream the video stream from camera at 640 x 480 resolution, MPEG-4, 10fps (also tried with 15, 30 fps). > > Software: For the Wifi client on the development board, I am using the ath9k driver with btcoex_enable=1. > 2-wire coexistence. I am allowing 40% of the time for Bluetooth an 60% of the time for WiFi. The period is around 200ms. > > Observations: > 1. The video streams are not smooth.
