hi, I want to make matlab communicate (several socket MATLAB customers) with a socket server (which is not matlab) via TCP/IP communication in real time but I have a delay pro

Here is the identical code of customers matlab

t = tcpip('127.0.0.1', 7777, 'NetworkRole', 'client');
fopen(t);
while true
    data =fscanf(t, '%c');
    disp(data);
end
T
H

When reading separate characters, fread() often makes more sense than fscanf() '%c' . It might not fix your problem, but it might reduce it

data = fread(t, [1 1], 'uchar')

Which MATLAB release are you using? These days tcpclient() is recommended

I've tried but here the client matlab does not accept even the data

[Walter Roberson]

I am not clear what you tried? Are you saying that when you used tcpclient() that the connection failed? Are you saying you used tcpclient() but using read() failed for it? [Note: tcpclient() uses read() and readline() not fread() -- and no fgets() for tcpclient() either.)

sorry sorry i rather believe the problem is from the matlab receiving pad

Hi, please how to run matlab and Simulink at the same time. In fact the matlab code must always be executed to recover a value coming from the server and this value must be sent to Simulink at the same time. Me when I run the matlab code it blocks the execution of Simulink. Help me !
