Hi everone, I'm pretty new to Max. I try to use Max to communicate with Arduino board by serial port, but I receive nothing from serial port.

Is there some steps I missed? Any kind of help would be appreciated!

Here is my arduino code, really simple right? 🤣

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  Serial.begin(9600);
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  Serial.println(random(100));
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(500);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(500);                      // wait for a second
}

Once I upload my code to the board, I close monitor and Arduino IDE.

Then I run my patcher, there is nothing on my console or message box, but '

here is my patcher, 

Board: Raspberry Pi Pico H
Arduino IDE: 2.0.1
Max version: 8.3.1
Windows 11

Can not receive data from serial port sending by Arduino (Win 11)
