I am using dsp.UDPReceiver objects in my code. There are times when I put my code into an idle state. When I transition back to an active state I want to flush out all the stale data in the UDP buffer. I have tried the reset method for this object, but that doesn't seem to do it. Right now as a work-around, I simply call the receiver object until it returns an empty matrix to clear the buffer. This is a bit crude but works. Is there a 'cleaner' way to flush the input buffer for a dsp.UDPReceiver?
Whatever is implemented, I need it to be compatible with code generation.
Thanks.

Hi Michael,
I understand that you are using "dsp.UDPReceiver" objects in your code and you need to flush out stale data in the UDP buffer when transitioning from an idle state to an active state.
I recommend using the "flush" function in MATLAB, specifically the "flush(u, "input")" syntax, which flushes the input buffer of the specified UDP socket. This function can help you achieve your goal of clearing the buffer. You can find more information and usage examples in the below documentation:-

Hope it helps.
Thanks,
Akash.
