Subject: [PATCH 08/13] Bluetooth: Stop ack_timer if ERTM enters in Local Busy or SREJ_SENT
Date: Mon, 31 May 2010 14:02:47 -0300	[thread overview]
Message-ID: <1275325372-5671-8-git-send-email-padovan@profusion.mobi> (raw)
In-Reply-To: <1275325372-5671-7-git-send-email-padovan@profusion.mobi>

The ack_timer is implemation specific, disabling it in such situation
avoids some potencial errors in the ERTM protocol.
