Data From Digital Scale With Arduino

Using Arduino Project Guidance

Hi, I want to ask, I have an arduino with max3232 rs232 to ttl connected to MKCells Di03 digital scales. I tried first with teraterm and received data as in the following picture.

Then I tried using arduino with the following coding

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11);  // RX, TX

void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  mySerial.begin(9600);
  Serial.println("Hello, world");
}

void loop() {  // run over and over
  if (mySerial.available()) {
    Serial.write(mySerial.read());
  }
  if (Serial.available()) {
    mySerial.write(Serial.read());
  }
}

And the data displayed on the serial monitor looks like this

In the weighing data above, every time there is new data he does not make a new line but continues sideways and for some reason I see in the arduino serial monitor there are additional characters that I don't know at the beginning and end of the weighing data. how do I retrieve the data so that it can be for example +00005011> to 5.0 or +00015511; to 15.5 ?

What instructions do you use to print on the monitor?

Please make sure you are posting matching code and monitor output

Yes the code above is the code I used, it just changed the setup from serial.println(“Goodnight moon!”) to serial.println(“Hello, Word”).
Then if what is drawn is in the serial monitor why can there be 3 lines of weighing data because previously I reset the arduino with the button on the arduino.

It seems to me that although there is some variation in separation characters ( : > or ? ) the reading is always preceded by a + sign

so you can use this as a flag.
When you recognise this you can take the next 8 characters and convert them to either a LONG in milligrams (presumably) or a float in grams or kilograms, whatever.

Hello lypus

Switch the terminal programme so that the datagram is presented in hexadecimal representation to determine the start and end characters.
