From 04fb7d9066dd9173ef0d4ccea8fe3bb59bd94605 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 30 Jun 2014 12:34:36 +0200 Subject: [PATCH] Bluetooth: Provide defaults for LE connection latency and timeout Store the connection latency and supervision timeout default values with all the other controller defaults. And when needed use them for new connections.
