How can I make DSP.UDPReceive block output only 1 instance of received packet instead of holding the value at its output until next packet arrives?

I am trying to set up simple UDP send and receive program with diffrent rates of transmission. In the same Simulink window, I am invoking UDPSEND once every 10 time-step (fixed discrete) but running UDPRECEIVE continuously (every time step). What UDPRECEIVE does is it holds the value for the subsequent 9 steps until it receives a new packet on the 11th (or n*11th) time-step. Can I make the RECEIVE block output a received packet only once?

If you have access to the Instrument Control Toolbox, you may want to consider using the UDP Send block from this toolbox as there is a blocking mode that seems to fit your workflow directly. Refer to the following documentation for more information:

If you are using the prerelease for R2018a, there is a new feature called "access latest data" which, as implied by the name, also seems to fit your workflow.

Hi Mark, thanks for your answer. I intend to use the Simulink model to run real-time in a dedicated RTT, hence need Code-Generation. ICT does not support code-generation (or does it?). 'Access Latest Data' feature, is it avaiable in the DSP blockset? Thanks!
