Hi, I need simulink to be able to receive udp data from an external source. I am using the UDP receive block. When the UDP communication is within the model (in localhost), everything works great. But, if I try to receive data from an external source I allways get the error:
Error in 'udp/UDP Receive': Received a fractional-length packet for the specified data type.
Can someone help? Thanks in advance.

I've had this issue before and it was related to the port already being used by another process. You may want to change you port and/or check to make sure the UDP port isn't already in use.
