I am trying to transfer data from Matlab running on a PC and wiznet wiz550io module. I am only able to send data one way from Matlab to wiz550io. Could someone please help me with the transfer of data from wiz550io to Matlab? Here is my code

if true
  try
%Create a client interface and open it.
t = tcpip('163.1.6.228', 8080, 'NetworkRole', 'client');
fopen(t);
% Write the waveform to the server session.
fwrite(t, 'GET10.55')
disp('1 Success!');
fclose(t);
catch
  disp('1 Failed!');
  fclose(t);
end
end
 if true
try
%Create a server interface and open it.
t = tcpip('163.1.6.228', 8080, 'NetworkRole', 'server');
fopen(t);
data = fread(t, t.BytesAvailable)
disp('2 Success!');
fclose(t);
catch
    disp('2 Failed!');
    fclose(t);
end
  end
