The key issue may be related to how the string is formatted in Java before being sent as a UDP packet to Simulink. Often, the mistake involves sending data like "123.456" instead of "123.456\n" or "123.456\r". The escape sequences at the end of the string signal the end of the message, which helps the receiving block recognize when to stop reading.
When using the Stream Input block in Simulink, the Message Terminator field plays a crucial role. More information about configuring this can be found here:
Alternatively, the Packet Input block in Simulink can be used to handle unformatted binary data and output a formatted string. This method requires specifying the packet size, which corresponds to a fixed number of decimal points. Additional details are available here:
Hope this helps.
