Using RTI Connector for Python.
On the output instance, is it possible to explicitly set a union discriminator?
I have a union with 2 members, where each member is associated with 2 discriminators. The default/first discriminator is always set on the various set_ calls.
The <types> below is contrived, but illustrates the situation.
Is it possible to set "struct_cd.cd" with the discriminator set to "D" rather than "C"?
Do you have an example of how to setup an event loop in python with the DDS Python Connector?
I only see input.wait() and connector.wait() on https://community.rti.com/static/documentation/connector/current/api/python/input.html but both appear to be blocking. How do I set up a way to register a call back when new messages are recieved?
I am implementing a python script which seeks to plot in real time read data from an RTI python connector.
When I reference a function rather than call a function which uses input.wait(), the python kernel crashes. Is there a reason why this happens?
I added a screenshot of the code. The kernel crashes at the animation call.
Hello:
There is an administration topic to control RTI data recorder. The topic is rti/service/admin/command_request.
Does anyone have a python example to do this remote control of the data recorder? Sending commands and processing replies.

Dear All!
I am trying to publish some sensor data via DDS from Python code.
Basically, the relevant parts of the code are:
with rti.open_connector(config_name="MyParticipantLibrary::MyPubParticipantT", url="Definition.xml") as connector:
self.output=connector.get_output("a::MyWriterT")
self.output.wait_for_subscriptions()
self.dds_instance=self.output.instance
And after some steps within the statemachine:
Hi
I want to use 2 connectors in my python program but I don't know why this error occurs
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!
