c6ad4a7927
This patch removes all uses of the adv auto-resume feature in the Bluetooth samples. The auto-resume feature is planned for deprecation. Samples that are not intended to demonstrate a technique to do with re-connection simply do not restart the advertiser, in interest of simplicity. The user is expected to reboot the sample when needed. Signed-off-by: Aleksander Wasaznik <aleksander.wasaznik@nordicsemi.no>
