Use with multiple A02YYUW

Hello there,

I have a question; how do we use 2 sensors at the same time?
When I tried to use with 2 sensors, I got wrong sum values for second sensor as shown below.

You can check my arduino loop method code as shown below.

// Defined variables;
unsigned char data[4] = {};
unsigned char data2[4] = {};

  do {
    for (int i = 0; i < 4; i++)
    {
      data[i] = mySerial.read();
    }
  } while (mySerial.read() == 0xff);

   mySerial.flush();

  do {
    for (int i = 0; i < 4; i++)
    {
      data2[i] = mySerial2.read();
    }
  } while (mySerial2.read() == 0xff);

 mySerial2.flush();

  if (data[0] == 0xff && data2[0] == 0xff)
  {
    int sum;
    sum = (data[0] + data[1] + data[2]) & 0x00FF;

    int sum2;
    sum2 = (data2[0] + data2[1] + data2[2]) & 0x00FF;


 Serial.print("sum1 ");
    Serial.print(sum);

    Serial.println();
    
    Serial.print("data[3] ");
    Serial.println(data[3]);

    Serial.print("sum2 ");
    Serial.print(sum2);


    Serial.println();

        
    Serial.print("data2[3] ");
    Serial.println(data2[3]);

// rest of code

Thank you!

Non-English characters in English README file

The compatibility tables have headers using (Chinese?) characters. Unfortunately I can't understand those. Can you please replace them with English translations ?

Thank you.

multiple sensors

Hello, I would like to connect multiple sensors through an usb-uart converter. I'm doing it on Jetson AGX XAVIER. How do I change the pins to read data in the python script? I saw that in the arduino example there is something as SoftwareSerial mySerial(11,10); // RX, TX. Could I do a similar thing in python?
Regards
