I give For practical information on working with multiple RMW implementations, see the “Working with multiple RMW implementations” tutorial. After calling write(), Fast DDS takes ownership of the sample and therefore it is no longer safe to make changes to that sample. Is it possible that CycloneDDS can communicate with FastDDS right now？ I saw eboasson answered "NO" by Issue1020, which was published in 2021. . Commercial support is also available; see the support page for You may also want to take a look at other open-source DDS implementations like OpenDDS, but I personally don't think they will fit your needs. 0 intraprocess vs Cyclone DDS 0.
