From 0493684ed2397e111574f343534d8e4ec440dfa5 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 14 Jul 2008 20:13:48 +0200 Subject: [Bluetooth] Disable disconnect timer during Simple Pairing During the Simple Pairing process the HCI disconnect timer must be disabled. The way to do this is by holding a reference count of the HCI connection. The Simple Pairing process on both sides starts with an IO Capabilities Request and ends with Simple Pairing Complete.
