From 3581508571b513ed2e66d71f9708d6be907460fd Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Thu, 26 May 2011 16:23:53 -0300 Subject: Bluetooth: Advertising entries lifetime This patch adds a timer to clear 'adv_entries' after three minutes. After some amount of time, the advertising entries cached during the last LE scan should be considered expired and they should be removed from the advertising cache. It was chosen a three minutes timeout as an initial attempt. This value might change in future. Signed-off-by: Andre Guedes Signed-off-by: Gustavo F.
