Is NDDS 3.x compatible with RTI Connext 4.x or above?

Note: Applies to NDDS 3.x and RTI Connext 4.x and above.

NDDS 3.x and RTI Connext 4.x (and above) are not wire-protocol compatible. Applications built with these 2 products cannot communicate with each other.

The attached 3.x to 4.0 Transition Guide will help you move your application to the 4.0 API. If you are transitioning to a more current release of RTI Connext 4.x or above, please refer to the individual transition guides available in the Documents section of the RTI customer portal.

If you can not migrate 3.x applications and interoperability with 4.x is a must, contact your account manager to explore specific solutions.
