RTI Connector for Connext DDS

RTI Connector for Connext DDS is a quick and easy way to access the power and functionality of RTI Connext DDS. It is based on XML App Creation and Dynamic Data.

RTI Connector was created by the RTI Research Group to quickly and easily develop demos and proof of concept. We think that it can be useful for anybody that needs a quick way to develop an application communicating over DDS databus. Thanks to the binding with multiple programming languages, you can integrate with tons of other available technologies.

The RTI Connector library is provided in binary form for selected architectures. Language bindings and examples are provided in source format.

For Go Connector, we leveraged cgo to call our C library, but we try to hide that from you using a nice Go wrapper. We tested with Go v1.11, v1.10 and v1.9.

Getting started

Be sure you have Go installed and set your go workspace ($GOPATH). Then run:

$ go get github.com/rticommunity/rticonnextdds-connector-go

Check out the Go Connector repository is cloned properly at the following location. $GOPATH/src/github.com/rticommunity/rticonnextdds-connector-go

Then, take a look at this document to build and run examples!

Platform support

We are building our library for few architectures only. Check them out here. If you need another architecture, please contact your RTI account manager or sales@rti.com.

If you want to check the version of the libraries you can run the following command:

strings librtiddsconnector.so | grep BUILD

Threading model

The RTI Connext DDS Connector Native API do not yet implement any mechanism for thread safety. Originally the Connector native code was built to work with RTI DDS Prototyper and Lua. That was a single threaded loop. We then introduced support for javascript, python, and Go. For now the responsibility of protecting calls to the Connector are left to the user. This may change in the future.


This is an experimental RTI product. As such we do offer support through the RTI Community Forum where fellow users and RTI engineers can help you. We'd love your feedback.


We do not have much documentation yet. But we promise you: if you look at the examples you'll see that is very easy to use.

For an overview of the API, check this page.
