Sending LargeData from Prototyper?

I'm trying to have the Prototyper Lua utility from v5.3.0 publish a large status & image-data containing message(~2MB) once every 10s for debugging purposes but only see the fields other than the image-data being populated in DDS Spy.

I've followed some guides regarding large data handling(asynchronous publishing, etc.) and can see the image-data field populated under ~65KB however when above that the field shows blank despite the rest of the message being popluated.

Is LargeData supported in the 5.3.0 Prototyper?  If so any suggestions are much appreciated, thanks!

Send String Arrays using Dynamic Data and Request-Reply pattern


I am a bit new to DDS. I am curently working with the request/reply pattern. I successfully managed to send requests and replies containing primitive types of data such as char, long, int, etc. What I am not trying to do is sending some string array with the request reply pattern and using Dynamic Data as the string array I'm trying to send must be custom made. Until now I managed to do something like this:


//Register the type support for creating string arrays

DDS_TypeCode* type = factory->create_struct_tc("MyType", structMembers, out_exc);
