From 5976e60811723220678ebdb2ea06fbb52fe900bd Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 6 Oct 2013 04:08:14 -0700 Subject: [PATCH] Bluetooth: Use helper function for re-enabling advertising When the all LE connections have been disconneted, then it is up to the host to re-enable advertising at that point. To ensure that the correct advertising parameters are used, force the usage of the common helper to enable advertising. The change just moves the manual enabling of advertising from the event handler into the management core so that the helper can be actually shared.
