Is there a way to specify which QoS profile a domain participant uses via XML?

Hey there,

I'm using the rti python connector for building a testing API and I need a way to specify the QoS profile for some of my domain participants. Currently they all are using the default profile which works for some topics but produces a mismatch for others. In general I can subscribe successfully to every topic but publishing does not work for some topics due to a QoS mismatch. As far as I can tell there's no functionality in the python connector for setting a QoS profile like there is mentioned in the RTI manual.

Any help would be appreciated, thanks!

Andrew

How to get all instance handles to the remote writer that changed liveliness?

Hi, 

I have a problem when using livelinessChangedStatus structure. In my project, I have one dataReader that listens to a topic which several dataWriters are publishing on. Every time when one or several dataWriters come offline/online due to network disconnect/reconnect, the function on_liveliness_changed(.....) is called, and I get a LivelinessChangedStatus struct. However, this struct only tells me the instance handle to the last remote writer that changed its liveliness, and this causes me a problem when several writers changed their liveliness at the same time.

Installing RTI DDS Toolkit for LabVIEW on a regular PC

Hi,

 

We are considering RTI DDS for our LabVIEW projects. I'm trying to set up and test the connection between a Windows PC and a regular laptop running LabVIEW RTOS.

When I try to install RTI DDS Toolkit for LabVIEW to the LabVIEW RTOS laptop using NI MAX, I do not see the component which is shown from the RTI_DDS_Toolkit_for_LabVIEW_GettingStarted.pdf on 1.2.1 - Installing RTI DDS Toolkit for LabVIEW Support Files on a Target. However, I do notice that the screenshot from the manual shows a CRIO-9068 is used for the toolkit.
