From d9483943601ba7095af42a159faacf7746a74bc9 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 23 Feb 2014 19:42:24 +0200 Subject: [PATCH] Bluetooth: Use hci_update_random_address() for initiating LE scan When we start LE scanning we need to update the local random address if necessary. This patch updates the code to use hci_update_random_address() for setting the own_address_type scan parameter and updating the local random address if necessary.
