From c9ecc48e2f3577a73dcd830d8b67ecc48e224465 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Thu, 15 Mar 2012 16:52:08 -0300 Subject: [PATCH] Bluetooth: LE support for MGMT stop discovery This patch adds LE support to MGMT stop discovery command. So, now we are able to cancel LE discovery procedures (LE-only and interleaved).
