Run "hciconfig hci0 lestates" And check the supported states. Also see Core Spec v4.0 page 1096 for more details. Some controllers don't support LE scanning and LE advertising at the same time, so make sure you don't have LE scanning enabled in "A" while trying to re-enable advertising. > 2.

See patches from Andre Guedes around May 31st (which are already upstream).
