From 4debf37ded8be1c8126d45aa4c1473b39afb2f77 Mon Sep 17 00:00:00 2001 From: Sudha Bheemanna Date: Thu, 8 Sep 2016 11:21:06 +0530 Subject: [PATCH] Bluetooth: Set filter policy for LE connection This patch sets the filter policy to a default value 0x01 during LE auto connection if the destination address is not set. And it updates the destination address once the LE connection complete event is recieved during LE auto connection. And for it checks valid destination address before cancelling LE connection when connection timeout occurs.
