I am trying to interface boltiot with Arduino with UART protocol. And I programmed boltiot in python using API
The python code:
from boltiot import Bolt

api_key = "XXXXXXXXX"

device_id = "XXXXXXX"

mybolt = Bolt(api_key,device_id)

response = mybolt.serialBegin(9600)

response1 = mybolt.serialRead('RX')

print(response1)

print(response)

Arduino Code

#include<SoftwareSerial.h>

SoftwareSerial mySerial(0,1); //Rx and Tx

void setup() {
  // put your setup code here, to run once:
    Serial.begin(9600);
    mySerial.begin(9600);

}

void loop() {
  // put your main code here, to run repeatedly:
  if(mySerial.available() > 0){
    
      mySerial.print("Amrapali");
      mySerial.println("    Santosh");
      
  }

}

please go through the screen shot what it is showing
