Subject: Enhance BT On scenario in power off
X-Git-Tag: accepted/tizen/unified/20180816.134643~5
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fconnectivity%2Fbluetooth-frwk.git;a=commitdiff_plain;h=aa9b3271329649a3289501711e53d39fe38318b6

Enhance BT On scenario in power off

[Problem] BT is not turned on when flight mode is unset during power
 off. This is not usual case but it happens sometimes in wearable model.
 Specific case is described in "Checking Method".
[Cause & Measure] If BT on is requested during power off, just update
 vconf of bt state. So that in next boot, BT is turned on.
[Checking Method] BT On -> Cool down (LimitAction) / Flight mode on ->
 BT Off -> Cool down (ShutDown) -> Flight mode off -> BT On, but it's not done
 -> Power off -> Power On -> BT should be turned on
