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 different languages including scripting languages. It builds on several powerful capabilities of Connext DDS including XML App Creation and Dynamic Data.

RTI Connector provides the ability for users of different languages to tap into the power of Connext DDS. Specifically users of Node.js/JavaScript, Python, Lua or Go. It helps the user write a (JavaScript, Lua, Python) script which can subscribe or publish data to the Connext Databus.

Key Features and Benefits of Connector

  1. Publish and Subscribe to Data on the Databus. Enables users of scripting languages to tap into the Connext Databus.
  2. Eases Technology Integration. Being a part of the Node.js, Python and Lua ecosystems allows easy integration with other technologies
  3. Quick Development of POCs and tests. Scripting languages are often used to quickly develop demos or proof of concepts (PoCs). Connector can also be used to create test applications.
  4. 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.
  5. Simplified API.


RTI Labs Project Type: A DDS-based technology in the form of a library with binding for scripting languages, such as Python, Javascript, 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 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. It is based on RTI Connext DDS 5.3.0. Connector has has its own versioning; currently it is at v.0.3.0.

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 5.3.0. It can thus interoperate with products compatible with RTI Connext DDS 5.3.0. Because of the standard RTPS protocol, this includes RTI products including Connext Micro (limited to the feature set of Micro), Labview Toolkit for Connext DDS, etc. It also includes some of our competitor products.

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

All versions of RTI Connector for Connext DDS are available for download here: https://github.com/rticommunity/rticonnextdds-connector.  Additionally, the launcher of the RTI Connext DDS 5.3.0 Evaluation and Standard bundles has a 'Labs" tab. Clicking this will redirect you here, where you can download Connector.

The RTI Connector common C library is provided for selected architectures here. Scripting language bindings based on the C library and examples for each language are provided in the following links.


Connector’s documentation is located in our GitHub repository. 

Python Connector
To get started with Python Connector, begin by reading the short README about the RTI Connector and proceed by downloading the software from GitHub.

You can follow the "Introduction to DDS using the RTI Connector in Python” presentation put together by Javier Povedano. The full set of examples is located on GitHub (here).

Javascript / Node.js Connector

Start by reading the short README about the RTI Connector and proceed by downloading the software from GitHub. You can also install it with npm; the readme contains the instructions.

Then you can follow the "Introduction to DDS using the RTI Connector in Javascript” presentation by Gianpiero Napoli. The full set of examples can be found on GitHub (here).

Go Connector
