Arduino Ethernet - some issues with UDP commuication

Projects Programming
6

Yes it was pretty easy! Line #13, instead of char packetBuffer[PACKET_SIZE]; the correct one is byte packetBuffer[PACKET_SIZE];

Anyway, I still can't understand why there's a misunderstanding between MAX and the Arduino.
This is my "new" arduino code

#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUPD.h>

#define localPort 7401    
#define BUFFER_SIZE 12   

byte mac[] = {0x90, 0xA2, 0xD3, 0xE0, 0x66};  
IPAddress ip(192, 168, 1, 177);              

byte packetBuffer[BUFFER_SIZE];               

EthernetUDP Udp;                              

void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
  Udp.begin(localPort);
}

void loop()
{   
  if (Udp.parsePacket() > 0)   
  {


    Udp.read(packetBuffer, BUFFER_SIZE);   
    for (int i = 0; i < BUFFER_SIZE; i++)  
    {
      Serial.print(packetBuffer[i]);
      if (i < 11)
        Serial.print(", ");
      else
        Serial.println(".");
    }   
  }
}

What I obtain is:
105, 110, 116, 0, 44, 105, 0, 0, 0, 0, 0, number. (number is what MAX sends)

The values before "number" never change

If I add the line - Serial.println(Udp.parsePacket()); - after line#23 I obtain:
0
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.

I don't know if you're good with MAX (I am not, these are the very first sketch I make) but I will upload the "code"

Also this is pretty easy and I can't see mistakes or something.

Need help! Thanks
