Hello  
I am doing a UDP communication job in Matlab and node red, however the communication I have is slow, especially when I send data from Simulink to node red, I don't know why this could be, I did the test by sending integers.  
In simulink I am receiving data, and when I get two-digit numbers, the second digit freezes when I try to decrease the number.
