From f15504788d7b1613ef2ef0a673cfe250c16a6b0d Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 24 Oct 2012 21:12:03 +0300 Subject: [PATCH] Bluetooth: Disallow LE scanning and connecting in peripheral role When an adapter is in the LE peripheral role scanning for other devices or initiating connections to them is not allowed. This patch makes sure that such attempts will result in appropriate error returns.
