configureTerminator(t,"LF");

Hello in the above code, "LF" what it means?

Thank you

[Deepu S S]

configureCallback(t,"byte",10,@readDataFcn);

Hi, the above code where is to put in server side or in client side??

Thankyou

[yanqi liu]

yes，sir

ts = tcpserver("127.0.0.1",4000)

ts = 
  TCPServer with properties:

        ServerAddress: "127.0.0.1"
           ServerPort: 4000
            Connected: 0
        ClientAddress: ""
           ClientPort: []
    NumBytesAvailable: 0

tc = tcpclient("127.0.0.1",4000)

tc = 
  tcpclient with properties:

              Address: '127.0.0.1'
                 Port: 4000
    NumBytesAvailable: 0

How can i send and recieve stream of data through tcpip in matlab??

Note: The server and client in same computer but different Matlab scripts.Is it possible to transmitte stream of data with in acomputer,like the system act as server and client.When i run server script it will send stream of data to the client,the client will recieve the stream of data from server.

Which MATLAB libraries i want to use ?

is there any existing MATLAB examples like this available in MathWorks?

[yanqi liu]

yes，sir，may be check

run in one MATLAB env

% server
close all;clear all;clc;
t_server=tcpip('0.0.0.0',4000,'NetworkRole','server');
fopen(t_server);
try_times=100;
for i=1:try_times
    pause(0.02);
    try
        data_recv=fread(t_server,t_server.BytesAvailable);
        fprintf('\n%s\n',char(data_recv));
    catch
        t_server.ValuesReceived;
    end
end

run in another MATLAB env

% client
close all;clear all;clc;
t_client=tcpip('localhost',4000,'NetworkRole','client');
fopen(t_client);
% data_send=sin(1:64);
txt_send='HELLO, Deepu S S'; 
pause(1);
% fwrite(t_client,data_send);
fprintf(t_client,txt_send);

we run the first、the second，and then，the first MATLAB env can get

this is string，may be add some encode、decode method，use it as communication demo

Thank you now its work. And like this can i send one file from one computer to another is it possible??????

[yanqi liu]

yes，sir，what is the file type？is it “.txt” or anything？

[Deepu S S]

.ASCII file

[yanqi liu]

yes，sir，may be use base64 encode to string and decode to file

[Deepu S S]

how ?
