From fc64361ac15318126c64193929616fc4832071a6 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 22 Oct 2015 09:38:31 +0300 Subject: [PATCH] Bluetooth: Disable auto-connection parameters when unpairing For connection parameters that are left around until a disconnection we should at least clear any auto-connection properties. This way a new Add Device call is required to re-set them after calling Unpair Device.
