[maemo-developers] trouble to disconnect from WiFi AP

[From: Jan Vachun]

Hi,

In my apllication I'm trying to ensure connection to specific Wifi
network Access Point AP. I'm using osso_iap_connect(....) call to
connect using previously configured profile and it works well when no
wifi connection is currently selected.
When N800 is already connected to another WiFi AP, calling
osso_iap_connect(....) blocks application until WiFi connection is
dropped using Connection manager UI.

calling osso_iap_disconnect(...) with OSSO_IAP_ANY or with realIAP
profile name as parameter returns no error but doesn't disconnect
current WiFi connection.

I have also tried to disconnect through D-BUS using
disconnect_iap_async() in following code, but it didn't work either.

Any hint will be really appreciated.



<--------------- begin of sample code -------------->

void send_message_no_reply(DBusMessage *msg);
int disconnect_iap_async(const char *iap);
DBusConnection *get_connection();

DBusConnection *get_connection()
{
    static DBusConnection *connection = NULL;

    if (connection == NULL) {
        connection = dbus_connection_open(
        DBUS_SYSTEM_BUS_DEFAULT_ADDRESS,
        NULL);

        if (!connection)
            return NULL;

        if (!dbus_bus_register(connection, NULL)) {
            dbus_connection_disconnect(connection);
            dbus_connection_unref(connection);
            connection = NULL;
            return NULL;
        }
    }



    return connection;
}




void send_message_no_reply(DBusMessage *msg)
{
    DBusConnection *conn;

    conn = get_connection();
    dbus_message_set_no_reply(msg, TRUE);
    dbus_connection_send(conn, msg, NULL);
}



int disconnect_iap_async(const char *iap)
{
  DBusMessage *msg;
  msg = dbus_message_new_method_call(
                        ICD_DBUS_SERVICE,
                        ICD_DBUS_PATH,
                        ICD_DBUS_INTERFACE,
                        ICD_DISCONNECT_REQ);
  if (msg == NULL)
        return -1;
  if (!dbus_message_append_args(msg, DBUS_TYPE_STRING, &iap,
DBUS_TYPE_INVALID))
  {
        dbus_message_unref(msg);
        return -1;
  }
  send_message_no_reply(msg);
  dbus_message_unref(msg);
  return 0;
}

<--------------- end of sample code ---------------->
