From 41c90c186a3b51207cb1f2583fbadec3c76e4730 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 23 Feb 2014 20:25:55 -0800 Subject: [PATCH] Bluetooth: Use privacy mode for non-connectable advertising When enabling non-connectable advertising, there is no need to advertise with a public address or static address. In case LE privacy has not been enabled a unresolvable private address will be used.
