python

Hi all,

I am currenlty testing the 7.0.0 EAR version with the new Python API Connext-Py and I have encountered several issues/bugs and was wondering what should/could I do to report them.

Here is the list:

hi,

I'm currently using connextpy, and trying to publish a topic that contains both FLAT_DATA language binding and SHMEM_REF transfer mode.
Through RTI Admin Console, I can see that I can write into basic fields of this message ("id" field below), however for some reason, the data I write in the arrays ("attribute.distance" field below) are not showing up.

hi

im trying to solve the problem where im using the same program to publish and subscribe to the same topic.

the usage is i get a cmd from the topic so i will reply to it using the same message with data populated in it.

i saw there is this ignore_participant fn that can be used to ignore the local publisher so the message wont be received by itself.

is there another method or something equivalent that i can do in the python api provided by rti.

Hi,

I am currently evaluating Connext DDS 6.0.1, especially also the Python version.

It seems that the usage of Python with IDL (converted to XML) is currently broken?!

If you follow the steps mentioned here https://github.com/rticommunity/rticonnextdds-getting-started/tree/master/2_hello_world/python you will get an error.

First I use  rtiddsgen -convertToXml ../hello_world.idl

And then  python3 HelloWorldPublisher.py which fails with:

Hi,

I’m relatively new to the whole DDS world so I’m hoping someone more experienced will know this off the top of their head. I mostly work in python on various data science topics. Recently there has been need for one of our pyrton scripts to communicate via DDS with embedded hardware.

Therefore the python library provided as part of the rticonnextdds-connector package looks quite appealing.

Main Question:

How do I explicitly fill out a union? The other examples given on the forum rely on it automatically figuring out what type to use, but the rtirecord struct (ab)uses the discriminator to mean different things!

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,
