Communicating DDS Entities with different type bounds

By default, a DataWriter of an unbounded type won’t be able to communicate with a DataReader of a bounded type. DDS includes the max size of a bounded type as part of the data type information (known as TypeCode or TypeObject). Since the data type information is used during the Discovery phase, if ...

Why does only one of my Reader VIs get the new samples?

A normal scenario in RTI Connext DDS is to have a Publisher that generates samples and several Subscribers that receive the generated data. In other words, the expected out-of-the-box behavior is for all Subscribers to get all the data. This is so because each Subscriber has its own DataReader for ...

How can I load a personalized QoS profile in RTI DDS Toolkit for LabVIEW?

QoS profiles provide a way to configure your DDS application, defining most aspects of the DDS paradigm and the underlying communication mechanisms. As part of RTI DDS Toolkit for LabVIEW we provide a set of pre-defined QoS profiles. These profiles solve general use cases such as a Reliable ...
