Return-Path: From: Arman Uguray To: linux-bluetooth@vger.kernel.org Cc: Arman Uguray Subject: [PATCH BlueZ 2/3] shared/gatt-server: Introduce shared/gatt-server. Date: Fri, 3 Oct 2014 15:39:10 -0700 Message-Id: <1412375951-13940-3-git-send-email-armansito@chromium.org> In-Reply-To: <1412375951-13940-1-git-send-email-armansito@chromium.org> References: <1412375951-13940-1-git-send-email-armansito@chromium.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch introduces bt_gatt_server which will implement the server-side of the ATT protocol over a bt_att structure and construct responses based on a gatt_db structure. --- Makefile.am | 1 + src/shared/gatt-server.c | 155 +++++++++++++++++++++++++++++++++++++++++++++++ src/shared/gatt-server.h | 47 ++++++++++++++ 3 files changed, 203 insertions(+) create mode 100644 src/shared/gatt-server.c create mode 100644 src/shared/gatt-server.h diff --git a/Makefile.am b/Makefile.am index 1a1a43f..2dfea28 100644 --- a/Makefile.am +++ b/Makefile.am @@ -114,6 +114,7 @@ shared_sources = src/shared/io.h src/shared/timeout.h \ src/shared/att.h src/shared/att.c \ src/shared/gatt-helpers.h src/shared/gatt-helpers.c \ src/shared/gatt-client.h src/shared/gatt-client.c \ + src/shared/gatt-server.h src/shared/gatt-server.c \ src/shared/gatt-db.h src/shared/gatt-db.c \ src/shared/gap.h src/shared/gap.c diff --git a/src/shared/gatt-server.c b/src/shared/gatt-server.c new file mode 100644 index 0000000..8e32def --- /dev/null +++ b/src/shared/gatt-server.c @@ -0,0 +1,155 @@ +/* + * + * BlueZ - Bluetooth protocol stack for Linux + * + * Copyright (C) 2014 Google Inc. + * + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
