How can I receive sensor data from ESP32 /M5 stick-c to MATLAB

I want to send the sensor reading from ESP32 M5 stick -C through udp Protocol and receive it in MATLAB. The problem is I don't know how, like I don't even have the code that I've been working on,

I'm using a randomSeed as the sensor reading for now.

I have referred from the code from YouTube link https://www.youtube.com/watch?v=1KLa1gwasJY&t=1s

I got error incompatible types in assignment of 'StringSumHelper' to 'char [8]'

Anyone can help me?

Arduino code:

#include <M5StickC.h>

#include <WiFi.h>

#include <WiFiUdp.h>

const char* ssid = "****";

const char* password = "*******";

char velores[]

//byte velores =0;

void setup() {

// put your setup code here, to run once:

Serial.begin(115200);

WiFi.mode(WIFI_STA);

WiFi.begin(ssid, password);

if (WiFi.status() == WL_CONNECTED)

{

Serial.println("WiFi connected");

Serial.print("Local IP: ");

Serial.println(WiFi.localIP());

}

M5.begin();

M5.Lcd.setRotation(3);

M5.Lcd.fillScreen(BLACK);

M5.Lcd.setTextSize(1);

M5.Lcd.setCursor(40, 0);

M5.Lcd.println("TEST");

M5.Lcd.setCursor(0, 15);

}

void loop() {

int val1 = random(0,50);

int val2 = random(51,100);

int val3= random(100,150);

velores= String(val1)+" "+String(val2)+" "+String(val3);

Serial.println(valores);

Udp.beginPacket("192.168.0.10", 45);

for(int i=0; i<1000;i++){

Udp.write(byte(valores[i]));

}

Udp.endpacket();

delay(10);

}
