I am trying to make a program listen for data coming via UDP, and do stuff. So I am working on a UDP listener. I am then running another instance of Matlab and trying to send data via UDP to test the listening.

However, I never get anything in the data stream. I am just trying to send the value 1 currently.

My Listener code:

U = udp('localhost', 4012);
fopen(U);
set(U,'Timeout',10);
continueListening = 1;
blah = 1;
while continueListening
      dataStream = fread(U,1) 
      blah
      if dataStream == 555;
          continueListening = 0;
          disp('Stoping acqusition');
      end
      blah = blah+1;   
  end
fclose(U);

And my writer code:

U = udp('localhost', 4012);
fopen(U);
fwrite(U, 1)
fclose(U);
