Security authentication handshake errors when RTI DDS and Cyclone DDS interoperability

Hello RTI Expert,

    Thanks for your support in advance.

    I am testing the DDS interoperability between RTI DDS and Cyclone DDS with enabling DDS Security feature. Unfortunately, it does not work.

    The scenario is described as follows.

    1. DDS Security files are created (ID CA, Permision CA, Keys, Governance file, Permission file, etc).

    2. Cyclone DDS and RTI DDS use and load these same security files.

    3. Cyclone DDS takes a subscriber role and RTI DDS is as publisher role.

Request reply with .net5

Dear Community,

I'm trying to use the request reply pattern in net5 under Linux (Debian 11 x64).

I see in the User Manual (Part4 Chapter 27) how they supposed to work, and I found cpp examples.

I also found a forum topic explaining the usage for dotnet framwork 4.5 (a dll reference is required from %programfiles%\...), but I can't seem to find neither the Requester nor the Replyer types for .net5.

Can you please help me how to use the request-reply pattern with .net5 (netcore) from under Linux (and possibly from under Windows too).

Thank you!

Multiple data writers

Hi,

I have a question on multiple data writer scenarios:

Assuming there is a topic

struct Foo

{

unint32 a;

unint32 b;

}

Two data writers: A and B can update this topic. They both have to subscribe to the topic too in order to get the update from each other. Is the following scenario possible

1. A publishes a sample (a=10 and b=20)

2. B  gets the sample ( a=10 and b=20)

3. A then publishes another sample ( a=11 and b=20)

ROS2 Action over Routing service

Hello,

i want to route certian topics from a docker network to an outside server, which shall perform a task. For that Ros2 has designed an action, wich i want to use,

For testing (avoiding building an docker image for each new try) i build up a test network with 3 different virtual machines:

VM A: Host Only Network (192.168.64.20/24)
VM B: Host Only Network (192.168.80.20/24)
VM Router: Two Host Only Networks (192.168.64.1/24 AND 192.168.80.24/24) which is the connection of the two networks.

Location of dds_c_buildid.h header file

Hello - I am porting version 2.4.10 of Micro DDS to Nucleus and have encountered a build error in which the header file dds_c_buildid.h cannot be found. This header file is included in several source files within the library source code, but I cannot find it anywhere in the distribution.  Can someone please advise as to the location of this file?
