Not able to obtain reading from RX of arduino

[sailek]

Grumpy_Mike:
The data sheet has no such variant.

You can have a HT9032B 8 dip, or a HT9032F-A 8 dip, or a HT9032S 8 sop but not what you said.

It is a HT9032D: 8-pin SOP package.
Dout is connected to pin 11 of arduino and Pdwn is connected to pin 10 of arduino.
The code is:

#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
char SBUF0 = 0;
 
void setup()
{
Serial.begin(1200);
}
 
void loop()
{
  Ht9032_get();
}
 
 
void Ht9032_get()
{
  while (Serial.available() > 0)  
  {
  //Serial.flush();
  SBUF0 = Serial.read();  
  Serial.print(SBUF0);
  }
}

I was also not able to open serial monitor
