From aa8af46e90869686e1a2707d0803ea9445a643a3 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 14 Oct 2013 21:15:26 +0300 Subject: [PATCH] Bluetooth: Fix updating scan mode in set_bredr() Now that the connectable setting is also applicable for the LE side it's possible that the HCI_CONNECTABLE flag is already set when changing the BR/EDR setting from false to true while the controller is powered. In this situation we need to update the BR/EDR scan mode to reflect the setting. Additionally, since HCI_CONNECTABLE also applies to LE we must not clear the HCI_CONNECTABLE flag when disabling bredr.
