Can not create a array message correctly

[Alex Bunnett]

Sorry to keep posting about this Problem but I can not find a solution for this problem.

I am unable to send a byte message across the bus correctly!

This is the methods I am creating the message with and reading with.
Can you see any problems?

When I read the message out I get the correct type and length but data is incorrect

Creating....

  message = dbus_message_new_method_call(CLIENT_SEND_NAME, CLIENT_SEND_OBJECT, SEND_INTERFACE_SERVER, "servermessage");

    if(message == NULL)
    {
                        __ALEX("Message NULL cant send");
                        return 0;
    }

    DBusMessageIter iter, sub;
    dbus_message_iter_init_append(message, &iter);

    char buf[2];

    buf[0] = DBUS_TYPE_BYTE;
    buf[1] = '\0';

    dbus_message_iter_open_container(&iter, DBUS_TYPE_ARRAY, buf, &sub);

    if(!dbus_message_iter_append_fixed_array(&sub, DBUS_TYPE_BYTE, &pBuff, len))
    {                   dbus_message_unref(message);
            return 0;
    }
    dbus_message_iter_close_container(&iter, &sub);

    if(!dbus_connection_send(_connection, message, &serial))
    {

                        dbus_message_unref(message);
                        return 0;
    }

    dbus_connection_flush(_connection); // force message to be sent now

Reading.....

DBusMessageIter args1, subiter;

            if (!dbus_message_iter_init(message, &args1))
            {
                        dbus_message_unref(message);
            }
 if ( dbus_message_iter_get_arg_type(&args1) == DBUS_TYPE_ARRAY)
            {
                        int maxlen = 100;
                        uint8_t pBuff1[100];

                        dbus_message_iter_recurse (&args1, &subiter);

                        dbus_message_iter_get_fixed_array(&subiter, &pBuff1, &maxlen); // this is incorrect not what I wrote in
            }

Thanks for your times
