FastDDS ShapesDemo Can not Communicate with DDS Blockset ShapesDemo

I followed the steps illustrated in DDS Blockset ShapeExample.mlx file and have build the shapesdemo.exe successfully. I first start the eProsima FastDDS Shapes Demo Application and set the Square Publisher and Circle Subscriber. When I run the shapesdemo.exe in MATLAB Command Windows, it quickly finished running and there is no display in FastDDS Shapes Demo Application.

I have also encountered this problem.Finally, the problem was solved by modifying the XML file.

shapesdemo_1.xml content:

<?xml version="1.0" encoding="UTF-8"?>
<dds>
    <profiles>
        <participant profile_name="shapesdemo_Library_shapesdemo_ShapesDomainLibrary_ShapesDomain_0">
            <domainId>0</domainId>
            <rtps>
                <builtin>
                    <discovery_config>
                        <leaseDuration>
                            <sec>DURATION_INFINITY</sec>
                        </leaseDuration>
                    </discovery_config>
                </builtin>
            </rtps>
        </participant>
        <publisher profile_name="shapesdemo_DataWriter_Pub_DataWriter_Writer">

@Allan Thanks a lot for your answer!

What is the stop time for the Simuilnk model? Set it to "inf" and regenerate code.

Hello @Mark McBroom, thanks for your answer. I have set the stop time to inf, but it still has no display in matlab command window. Howerver, I configured shapesdemo model with RTI Connext DDS, it works correctly.

The image illustrated as follows is the runing result of FastDDS configuration
