TCPIP communication between Matlab - Arduino. Stuck at fopen even when Arduino indicated a connection has been established.

Here's my Arduino Code:

#include <WiFi101.h>
// To connect to the server on laptop
char ssid[] = "EEELAB";
char pass[] = "@adelaide";
int status = WL_IDLE_STATUS;
IPAddress server(129,127,225,25);
WiFiClient client;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  
  // Setup wifi connection
  Serial.println("Connecting to wifi.");
  while (status != WL_CONNECTED) {
    Serial.println("Can't connect to wifi, try again.");
    status = WiFi.begin(ssid, pass);
  }
  delay(10000); // If don't include this, it won't work
                // don't know why, can anyone figure out??
  
  // Setup server connection
  Serial.println("Connecting to server.");
  int j = client.connect(server, 1234);
  while (j != 1)  {
    Serial.println();
    Serial.println(j);
    Serial.println("Can't connect to server, try again.");
    j = client.connect(server, 1234);
  }
  Serial.println("Done connecting to server");
}
void loop() {
  // put your main code here, to run repeatedly:
  if (client.available()) {
    int a = client.read();
    Serial.print("I got this from client: ");
    Serial.println(a);
    Serial.println();
  }
}

And here's my Matlab:

t = tcpip('129.127.225.25',1234,'NetworkRole', 'server')
fopen(t)

On the Arduino, I can see on Serial Monitor that it has "Done connecting to server", but fopen still stuck at a loop and not returning. Any idea?

在 MATLAB Online 中打开

t = tcpip('localhost',1234,'NetworkRole', 'server')

might help, maybe

@Walter: nope, same thing.
