Return-Path: From: Claudio Takahasi To: linux-bluetooth@vger.kernel.org Cc: claudio.takahasi@openbossa.org Subject: [PATCH BlueZ v2 16/18] gatttool: Add unix socket connect Date: Tue, 21 Jan 2014 10:26:52 -0300 Message-Id: <1390310814-19880-17-git-send-email-claudio.takahasi@openbossa.org> In-Reply-To: <1390310814-19880-1-git-send-email-claudio.takahasi@openbossa.org> References: <1390310814-19880-1-git-send-email-claudio.takahasi@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: This patch adds the initial support for GATT procedures over unix socket transport on command line mode (one-shot command). Temporary solution to allow local GATT procedures testing. --- attrib/gatttool.c | 27 ++++++++++++++++++++------- attrib/gatttool.h | 1 + attrib/utils.c | 54 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 75 insertions(+), 7 deletions(-) diff --git a/attrib/gatttool.c b/attrib/gatttool.c index ebc8123..d701f7b 100644 --- a/attrib/gatttool.c +++ b/attrib/gatttool.c @@ -29,7 +29,6 @@ #include #include #include -#include #include #include @@ -53,6 +52,7 @@ static int opt_end = 0xffff; static int opt_handle = -1; static int opt_mtu = 0; static int opt_psm = 0; +static gboolean opt_local = FALSE; static gboolean opt_primary = FALSE; static gboolean opt_characteristics = FALSE; static gboolean opt_char_read = FALSE; @@ -511,6 +511,8 @@ static GOptionEntry options[] = { "Specify local adapter interface", "hciX" }, { "device", 'b', 0, G_OPTION_ARG_STRING, &opt_dst, "Specify remote Bluetooth address", "MAC" }, + { "local", 'L', 0, G_OPTION_ARG_NONE, &opt_local, + "Use unix socket transport (local communication)", NULL }, { "addr-type", 't', 0, G_OPTION_ARG_STRING, &opt_dst_type, "Set LE address type.
