From 037fc415bce5ac7604ac52216ec03d011f81e5b0 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 29 Jun 2014 16:43:27 +0200 Subject: [PATCH] Bluetooth: Use LE connection parameters if known When the LE connection parameters for connection latency and supervision timeout are known, then use then. If they are not know fallback to defaults.
