From f7520543ab40341edbc2aeee7fef68218be19a0a Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 20 Jan 2011 12:34:39 +0200 Subject: [PATCH] Bluetooth: Add connected/disconnected management events This patch adds connected and disconnected managment events to track the connection status to remote devices. The events map directly to successful connection complete and disconnection complete HCI events for ACL links. Signed-off-by: Johan Hedberg Signed-off-by: Gustavo F.
