Hi all,

I am having an issue where my script command XMLRPC is being delayed on the first command.

here is some background information:

My program uses a XMLRPC method outside of the script command for some functionality, like actuate/ Home/ settings:

ie:  
xmlRpcDaemonInterface = new XmlRpcMyDaemonInterface(“127.0.0.1”, 33000);  
xmlRpcDaemonInterface.ACTUATE();

For the main program my Cap uses the normal URScript method :

ie:  
writer.appendLine(XMLRPC\_VARIABLE+“= rpc\_factory("xmlrpc","[http://127.0.0.1:33000](http://127.0.0.1:33000)")”);  
writer.appendLine(“ESU.generic\_command()”);

Both of them works as intended. if they are **not used sequentially**.

My problem is that if send the actuate command and then start a program there is a 3 second delay before the command in the script is sent to my daemon. I debugged my cap and it seems to be somewhere in the writer.

How can I reduce the delay time on the first command under this scenario?

Thanks,

Mat. O.
