From 2d28cfe7aada495f87bb439151e9bcc86998fb6d Mon Sep 17 00:00:00 2001 From: Jakub Pawlowski Date: Sun, 1 Feb 2015 23:07:54 -0800 Subject: Bluetooth: Add le_scan_restart work for LE scan restarting Currently there is no way to restart le scan, and it's needed in service scan method. The way it work: it disable, and then enable le scan on controller. During the restart, we must remember when the scan was started, and it's duration, to later re-schedule the le_scan_disable work, that was stopped during the stop scan phase.
