From c25dfc610b983f74f05b3c12d9ad4ff4af6cd858 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 6 Oct 2013 02:08:36 -0700 Subject: [PATCH] Bluetooth: Use random address if public address is not available For single mode LE-only controllers, it is possible that they come without a public address. If a public address is not available, then use the random address for connection establishment and scanning.
