M5Stack and MAX/MSP via WiFi, UDP

Hi,

I want to send some data from MAX to M5Stack via WiFi and UDP.
I tried following some articles, but my M5Stack still can't receive any data.

This is the M5Stack code:

----------------------------------------
----------------------------------------

#include <M5Stack.h>
#include <WiFi.h>
#include <WiFiUdp.h>

const char* ssid = "wifi name";
const char* password = "wifi password";
const char* host = "ip address";

const unsigned int inPort = 80;

WiFiClient client;
WiFiUDP Udp;

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);

M5.begin();
M5.Speaker.setVolume(1);
WiFi.disconnect();
delay(1000);
M5.Lcd.println("START");
WiFi.begin(ssid, password );
while ((!WiFi.status()== WL_CONNECTED)){
delay(300);
M5.Lcd.println("...");
}
M5.Lcd.println("connected");
Udp.begin(inPort);
}

void loop(){
int packetSize = Udp.parsePacket();
if(packetSize > 0){
M5.Lcd.println("received data");
}
}

----------------------------------------
----------------------------------------

And this is the maxpatch:

I wonder if it's because the port is incorrect, how can I find the right port...
Or is it the IP address that is wrong?
Do both MAX/MSP and M5stack have to connect to the same wifi?

Please advise if there's anything wrong with the code/patch.

Thank you in advance.

Best regards!
