Return-Path: From: Anderson Briglia To: linux-bluetooth@vger.kernel.org Cc: Anderson Briglia Subject: [PATCH v3 2/2] Bluetooth: Implement LE Set Scan Enable cmd Date: Mon, 13 Sep 2010 09:22:02 -0400 Message-Id: <1284384122-8393-2-git-send-email-anderson.briglia@openbossa.org> In-Reply-To: <1284384122-8393-1-git-send-email-anderson.briglia@openbossa.org> References: <1284384122-8393-1-git-send-email-anderson.briglia@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch implements LE Set Scan Enable command for dual mode and Low Energy hci controllers. It also adds new HCI flags in order to indicate the LE Scanning state for userland applications and kernel itself.
