Return-Path: From: Anderson Briglia To: linux-bluetooth@vger.kernel.org Cc: Anderson Briglia Subject: [PATCH 2/2] Bluetooth: Implement LE Set Scan Enable cmd Date: Mon, 23 Aug 2010 15:30:15 -0400 Message-Id: <1282591815-26934-2-git-send-email-anderson.briglia@openbossa.org> In-Reply-To: <1282591815-26934-1-git-send-email-anderson.briglia@openbossa.org> References: <1282591815-26934-1-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.
