Can FastDDS communicate with RTIDDS?

hello，I have been using DDS deployed on the Speedgoat for communication recently, and the DDS Blockset documentation says that Simulink Real-Time only supports Eprosima's FastDDS, but we need to communicate with RTIDDS on the Speedgoat. When I tested communication between two computers running Simulink (not Simulink Real-Time) and found that FastDDS can communicate with each other, RTIDDS can also communicate with each other, but FastDDS and RTIDDS cannot communicate, and there is an error when communicating between the Speedgoat and RTIDDS.

"but FastDDS and RTIDDS cannot communicate, and there is an error when communicating between the Speedgoat and RTIDDS."

Can you share what is the error exactly?

Hi @坚袆,

Cross communication between FastDDS(in Speedgoat) and RTI(any other network connected system) is possible without much change. You needs to only maintain to match the Domain, Publishers/Subscriber information, Packet definition and data types between the program.

If it does not resolve the issue, please share reproduction steps and error message that you are encountering.

Thank you for your reply，there was a problem with my parameter settings before, but I've fixed it now.
