From e1171e8d9c50c38a9adba72bb23949d9b975335c Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 19 Oct 2012 20:57:45 +0300 Subject: Bluetooth: Add initial support for LE-only controllers This patch splits off most the HCI init sequence commands from a fixed set into a conditional one that is sent once the HCI_Read_Local_Features and HCI_Read_Local_Version_Information commands complete. This is necessary since many of the current fixed commands are not allowed for LE-only controllers.
