FastDDS ShapesDemo Can not Communicate with DDS Blockset ShapesDemo

20 views (last 30 days)
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">
<topic>
<name>Circle</name>
<dataType>ShapeType</dataType>
<kind>WITH_KEY</kind>
</topic>
</publisher>
<subscriber profile_name="shapesdemo_DataReader_Sub_DataReader_Reader">

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
