Easy Experimentation and Rapid Deployment of DDS Test Applications with Connector Libraries


RTI Connector for Connext® DDS is a quick and easy way to access the power and functionality of RTI Connext DDS from a variety of popular scripting languages. It builds on several powerful capabilities of Connext DDS including XML-Based Application Creation and Dynamic Data.

With RTI Connector, developers can use their favorite scripting languages to tap into the power of Connext DDS to rapidly create prototypes or test scripts using JavaScript, Lua, or Python. The script can then subscribe or publish data directly to the Connext Databus.

Key Features and Benefits of RTI Connector

  • Publish and Subscribe to Data on the Databus. Enables users of scripting languages to tap into the Connext Databus.
  • Eases Technology Integration. Being a part of the JavaScript, Python and Lua ecosystems allows easy integration with other technologies.
  • Quick Development of POCs and tests. Scripting languages are often used to quickly develop demos or proof of concepts (PoCs). RTI Connector can also be used to create test applications.
  • XML-Based Configuration. DDS entities and QoS configurations can be defined in XML, and it enables users to focus on business logic in script languages by decoupling from communication entities.
  • Simplified API. Developers can stay focused on the value of their scripts rather than spending time learning how to use APIs.


RTI Labs Project Type. A DDS-based technology in the form of a library with binding for scripting languages, including Python, JavaScript, Go and Lua.

Maturity level. Experimental.

Support. This is an experimental RTI product. As such, we only offer support through the RTI Community Forum where fellow users and RTI engineers can help you. Additionally, along with your questions, we encourage you to post your feedback on the Community Forum! (we'd love your feedback on RTI Connector!).

Intent. Depending on the customer feedback (although currently it looks good), we’re planning on future development.

Feedback. You can provide feedback via the RTI Community Forum.

Project Version Information. The latest version of RTI Connector is v0.4.0 which is based on RTI Connext DDS v6.0.0.

Which platform(s) is it available on? You can view the full list of platforms here.

Product compatibility. The RTI Connector Library has been built with the latest version of Connext DDS and is fully interoperable with products compatible with RTI Connext DDS 6.0.0. Because of the standard RTPS protocol, this includes RTI products including Connext DDS Micro (limited to the feature set of Micro), RTI DDS Toolkit for LabVIEW, etc.

For additional information on language support and versioning, please view the README doc, located in our GitHub repository.
