From d04aef4cccf203fdfd1716e9ba458060cbab0928 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Fri, 27 Jul 2012 19:32:56 -0300 Subject: Bluetooth: Refactor LE connection into its own function The code that handles LE connection is already quite separated from the rest of the connection procedure, so we can easily put it into its own.
