Communicating through UDP for Windows 7

Hello everyone,

I’m doing a project that involves using the Wifly Shield to receive instructions from a program running in a Windows 7 machine, in order to control a couple of LEDs connected to the Arduino. The program running on the client side was made with MAX/MSP 5.

Now, what the Arduino does is, after it receives the instructions that come in a string from the program, it replies with a

SPI_Uart_println("1");

back to the computer. The MAX/MSP5 program listens to port 8080 for any communication, and thus receiving a “FULL PACKET” whenever the Arduino responds with the previous code.

This works perfectly on Mac OS X, but unfortunately this must be used with a windows 7 machine, in which it doesn’t work at all. It simply doesn’t “find” this communication.

The firewalls are disconnected, and the 8080 port is open.

Therefore, I have no more ideas as to what might be the problem, and how we can solve it.

Does anyone have any idea as to what this might be?

Thank you in advance.
