From 04837f6447c7f3ef114cda1ad761822dedbff8cf Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 3 Jul 2006 10:02:33 +0200 Subject: [Bluetooth] Add automatic sniff mode support This patch introduces the automatic sniff mode feature. This allows the host to switch idle connections into sniff mode to safe power.
