General Dynamics

All,

I have a question in regards to topic version differences between the publishing application and the subscribing application...

If I add an additional XML element to particular topic in the QOS configuration for the Publisher side (newer version of the topic)  but do not add that same additional element to the QOS Configuration for the Subscriber (current version of the topic)  what happens?

What happens when the Publisher sends a sample with that new element?

Does the DataWriter send that element to the Subscriber?

Hi,

Hi,

I'm using dds_consumer telegraf(inputs.dds_consumer) for consume dds data and trying to insert this data into influxdb2.1 version using telegraf outputs.influxdb_v2 plugin. However, data insertion in influxdb2 is failing with following error.

shapes-telegraf | 2022-04-06T19:55:00Z E! [agent] Error writing to outputs.influxdb_v2: Post http://localhost:8086/api/v2/write?bucket=metrics&org=company: dial tcp 127.0.0.1:8086: connect: connection refused

We have a need to use DynamicData with a custom transport using the modern C++ API.
I was able to generate and run the custom FILE transport example for C++11 but that uses an IDL defined data type, CustomTransport.

I have a HelloWorld publisher and subscriber that use DynamicData that I was hoping to get working with the custom FILE transport instead of the built-ins transports.
I was hoping I might be able to simply use the custom_transportPlugin.cxx and hpp files generated by the custom transport example and change "CustomTransport" to "dds::core::xtypes::DynamicData".

Using the DDS Modern C++ API 6.1.0

I'm trying to use rti::topic::find_topics() to get all the local topics from my local domain participant but I can't get the correct syntax.

The following throws the runtime exception: Can't create an AnyTopic from a native topic. Try a typed Topic<T> instead

    std::vector<dds::topic::AnyTopic> topics;
    uint32_t topicCount = rti::topic::find_topics(participant, std::back_inserter(topics));

While this gives a various compilation errors:

On the RTI Code Generator 2.0 Architecture Overview powerpoint (RTI_rttiddsgen_architecture.pptx), it says on the 6th slide that "The AST is equivalent to the simplified XML generated with rtiddsgen 1".  Does this mean that rtiddsgen 2 (which, as I understand, comes with RTI Connext version 5.1.0) will no longer output the simplified XML?

I can't seem to generate example C# code that doesn't depend upon .net 4.0.  Even the sample code, \rticonnextdds-examples\listeners\cd code, generates an example that gives me the following warnings for the publisher and subscriber code.
