[Bluez-devel] audio service

Hi all,
I was trying to write simple program for a2dp in C language. This is the
program that I m trying to run......



#include <string.h>
#include <ctype.h>
#include <unistd.h>
#include <glib.h>
#include <dbus/dbus-glib.h>
#include <dbus/dbus-glib-lowlevel.h>
#include <dbus/dbus-glib-bindings.h>

#include <bluetooth/bluetooth.h>

#include "marshal.h"
#include "marshal.c"


GMainLoop *loop;

static void
session_created ()
{
    g_message ("a2dp device created");
}

static void
session_removed (DBusGProxy *proxy, const char *session_object, gpointer
user_data)
{
    g_message ("playing");

}


int
main ()
{


    char* address = "00:19:63:EF:83:17";

    DBusGConnection *dbus_connection;
    DBusGProxy *dbus_proxy;
    GError *error = NULL;
    int ret;
    char *id;
    gchar *object_path = NULL;

    g_type_init ();
    id = (char*) g_malloc0(50);
    dbus_connection = dbus_g_bus_get (DBUS_BUS_SYSTEM, &error);
    if (error) {
        g_warning ("%s", error->message);
        g_clear_error (&error);
    }
    error = NULL;

    dbus_proxy = dbus_g_proxy_new_for_name (dbus_connection, "org.bluez",
"/org/bluez", "org.bluez.Manager");
    dbus_g_object_register_marshaller (marshal_STRING__STRING,
G_TYPE_NONE,
                                                    G_TYPE_STRING,
                                                    G_TYPE_STRING);

    dbus_g_proxy_call (dbus_proxy,
"ActivateService",&error,G_TYPE_STRING,"audio",G_TYPE_INVALID,G_TYPE_STRING,id,G_TYPE_INVALID);
    if(error != NULL){
        g_print("ERROR : %s",error->message);
        //exit(0);
    }
    else
        g_print("id = %s",id);

    error = NULL;

    dbus_proxy = dbus_g_proxy_new_for_name (dbus_connection,id,
                                 "/org/bluez/audio",
                                 "org.bluez.audio.Manager");

    ret = dbus_g_proxy_call (dbus_proxy, "CreateDevice", &error,
                            G_TYPE_STRING, address,
                            G_TYPE_INVALID,
                            DBUS_TYPE_G_OBJECT_PATH, &object_path,
                            G_TYPE_INVALID);
    if (!ret) {
        g_warning ("Error1: %s", error->message);
        g_clear_error (&error);
        return FALSE;
    } else
        g_message ("Object path: %s", object_path);

    dbus_proxy = dbus_g_proxy_new_for_name (dbus_connection,
"org.bluez",
                                 object_path,
                                 "org.bluez.audio.Sink");

    dbus_g_proxy_add_signal (dbus_proxy, "Connected", G_TYPE_INVALID,
G_TYPE_INVALID);
    dbus_g_proxy_connect_signal (dbus_proxy, "Connected", G_CALLBACK
(session_created),
                   NULL, NULL);

    dbus_g_proxy_add_signal (dbus_proxy, "Playing", G_TYPE_INVALID,
G_TYPE_INVALID);
    dbus_g_proxy_connect_signal (dbus_proxy, "Playing", G_CALLBACK
(session_removed),
                       NULL, NULL);


    dbus_g_proxy_call (dbus_proxy, "Connect", &error,
                            G_TYPE_INVALID,
                            G_TYPE_INVALID);
    dbus_g_proxy_call (dbus_proxy, "Play", &error,
                            G_TYPE_INVALID,
                            G_TYPE_INVALID);

    loop = g_main_loop_new (NULL, FALSE);
    g_main_loop_run (loop);


    return 0;
}


But getting these error message while running........

[Invalid UTF-8] id = \xb0\xe1\x04\x08
** (process:6157): WARNING **: Error1: Method "CreateDevice" with signature
"s" on interface "org.bluez.audio.Manager" doesn't exist


PLz help me out......

Thanks in advance.....
