From e04fde60efabe27afdbe041e3e5a09ec752ec9d2 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 23 Jun 2014 11:40:04 +0200 Subject: [PATCH] Bluetooth: Store current LE connection parameters in hci_conn struct The LE connection parameters are needed later on to be able to decide if it is required to trigger connection update procedures. So when the connection has been established successfully, store the current used parameters in hci_conn struct.
