From: Adrian Chadd To: sandeep suresh Cc: Ath9k-devel , Linux Wireless List Content-Type: text/plain; charset=UTF-8 Sender: linux-wireless-owner@vger.kernel.org List-ID: Hi! I don't know if you can do simulaneous wlan and BT RX - especially since WLAN RX sometimes requires ACKs to be sent. :) But for multicast, sure. You'd have to check the NIC schematic and antenna switch programming to see if you can do simultaneous wlan RX (with no TXing, eg RTS/CTS, ACK, etc) whilst also doing BT RX. As for BT_ACTIVE -> powersave; I don't think you can get interrupts based on that, but you can poll the gpio pin yourself and then tell the driver to not transmit and/or enter sleep state. Entering sleep state requires that you send some frame anyway to tell the AP you're going to sleep. -a
