From 3f7a56c4ff438f4727439cb048034f56320dd228 Mon Sep 17 00:00:00 2001 From: Mat Martineau Date: Tue, 23 Oct 2012 15:24:23 -0700 Subject: [PATCH] Bluetooth: Start channel move when socket option is changed Channel moves are triggered by changes to the BT_CHANNEL_POLICY sockopt when an ERTM or streaming-mode channel is connected. Moves are only started if enable_hs is true.
