From 8c84b83076b5062f59b6167cdda90d9e5124aa71 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 16 Jan 2009 08:17:51 +0100 Subject: Bluetooth: Pause RFCOMM TX when encryption drops A role switch with devices following the Bluetooth pre-2.1 standards or without Encryption Pause and Resume support is not possible if encryption is enabled. Most newer headsets require the role switch, but also require that the connection is encrypted. For connections with a high security mode setting, the link will be immediately dropped. When the connection uses medium security mode setting, then a grace period is introduced where the TX is halted and the remote device gets a change to re-enable encryption after the role switch. If not re-enabled the link will be dropped.
