Octave as a client in a server-client configuration

[cblou]

Hi,

I am using a motion tracking software ( TIY <https://code.google.com/p/tiy/> 
) to obtain the position of a robot. I need to use octave to control the
robot. The tracking software works as a server/client over a network and it
sends a string containing the information position I need.

The following code is the information I have on the server configuration,
from an XML file

        <multicast_port>30000</multicast_port>
        <multicast_adress>"239.255.0.1"</multicast_adress>
        <listen_address>"0.0.0.0"</listen_address>
        <client_update_intervall_ms>1</client_update_intervall_ms> //  Link to 
the
code
<https://code.google.com/p/tiy/source/browse/trunk/src/config_run_parameters.xml>
  

I also have an example server written in C++ that outputs the information to
a console.  Here is the relevant code of the client:

        // Start Client
    boost::asio::io_service io_service;
        
    tiy::MulticastClient multicast_client(io_service,
        boost::asio::ip::address::from_string(listen_address),
        boost::asio::ip::address::from_string(multicast_adress),
        multicast_port_short,
        do_debugging);
        
        // Run Update Loop
        std::string data_string;

        for(int i = 0; true; i++)
        {                       
                if (multicast_client.getReceivedString(data_string))
                {
                         //////////////// DO WHAT YOU WANT ////////////////
                        std::cout << "Received: " << data_string << std::endl;  
                
                }
                
        
boost::this_thread::sleep(boost::posix_time::milliseconds(client_update_intervall_ms));
 
        } // Complete code available at  here
<https://code.google.com/p/tiy/source/browse/trunk/src/client.cpp>  . 

I want to implement the client in Octave but I have little experience with
networks. I have been looking at MPI and octave-daemon for quite a while but
I cannot find an example similar to what I need.

Thank you very much,

Charles
