From 0b1db38ca26b322296cbd141f3080eccfe1cc3e1 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 28 Oct 2014 22:23:27 +0100 Subject: [PATCH] Bluetooth: Fix check for direct advertising These days we allow simultaneous LE scanning and advertising. Checking for whether advertising is enabled or not is therefore not a reliable way to determine whether directed advertising was used to trigger the connection creation. The appropriate place to check (instead of the hdev context) is the connection role that's stored in the hci_conn. This patch fixes such a check in le_conn_timeout() which could otherwise lead to incorrect HCI commands being sent.
