Hi,
I am trying to install RTI Connext Nano-agent using the Nano-agent Manual but I get error shown in the attached figure. What should I do?

Thank you.

Hi, I am currently trying to compile a ros distribution on gentoo in order to create a minimal OS for our robot.
However, this package is a major dependancy for ROS2 and is not distributed on gentoo.
I was wondering if it was possible to release the package for gentoo.

Hi all,

I hope someone here can help me, been looking a lot through the documentation and I can't seem to figure out what I'm missing.

I have been trying to get RTI Connext DDS Micro (2.4.14) to work on a microcontroller, the Nucleo-H745ZI-Q.

The furthest I have now gotton is that i was able to create a data reader that is visible in the RTI Administration Console (see attachment). But as you can see there is no IP address or locators data, which makes it that the microcontroller can't receive packages.

Hello, 
I am new to DDS and i just tried the below link examples, i am able to publish and subscribe the message within the local network.

https://community.rti.com/static/documentation/connector/current/api/python/getting_started.html#installing-rti-connector-for-python

I wanted to try exchange messaging over the internet, is there any example code like the above? specific to internet messaging pub/sub?

kindly share the link if any.

Regards

Hi, 

we have a board with micro DDS and it worked fine with interface 'fec0' (192.168.3.100/24). Later we ported same software to a different board. The new board has a vlan ('vlan10', 192.168.8.100/24). Now it didn't work anymore. 

I did change allowed interface list during registration,

  rti_me::RtRegistry* reg = dds_factory_.createRtRegistry(
      std::move(rti_me::UdpIntfFactoryPropertyBuilder()
                    .allowInterface(util::Span<const util::StaticString<255>>{kAllowedInterfaces})

Hi all,

It will be really great if someone could answer my questions, because I have been trying to get the communication working successfully between my Windows PC and Embedded Board using Connext DDS Micro 3.0.0.

Any kind of help will be more than appreciated to get the communication working between my Embedded Board(Publisher) and my Windows PC(Subscriber) for HelloWorld_dpde example in C.

I am using Connext DDS Micro 3.0.0 and trying to communicate between Windows 7 machine and an ARM based Real Time Architecture microcontroller board with FreeRTOS and lwIP.

I'm trying to set up a HelloWorld subscriber on a VxWorks 7 system but I am getting a number of undefined symbols.

Hello,

We would like to use the rticonnextdds-connector because we have a Python program which we want to communicate with others DDS modules. However, our platform is not supported. It is armv7-qnx6.5.0.

Would it be possible a new port? If not, we think to use https://github.com/forrestv/pyDDS but its API is poor and we want to use the dynamic data, for that, the RTI Connector seems much better solution.

Thank you in advance.

Best regards,

I am attempting to create a Connext 5.1.0 application for vxWorks 6.9 on a vxsim (vxWorks simulator) target. The simulator runs on a win7 host with the RTI pentiumVx6.9gcc4.3.3 target libraries. I created a HelloWorld app per the Getting Started Embedded Systems Addendum.

On subscriber (or publisher) startup, the following message is displayed after calling DDSDomainParticipantFactory::get_instance():

RTIOsapi_getFirstValidInterface:OS ioctl(SIOCGIFCONF)() failure, error 0X6: S_errno_ENXIO
