AWS MQTT Connection in a program

[reddy9698]

I've been meaning to implement the process mentioned by @davegravy in a code.
This is the program that I'm using in the void loop part.

`
modem.sendAT("+SMCONN");
if (modem.waitResponse(1000L, res) == 1) {
res.replace(GSM_NL "OK" GSM_NL, "");
Serial.println(res);
Serial.println("connection!!!!");
}

res="";

modem.sendAT("+SMPUB = "BasicPubSub", 425,0,0");
if (modem.waitResponse(10000L, res) == 1)
{
res.replace(GSM_NL "OK" GSM_NL, "");
Serial.println(res);
Serial.println("datssent");
res="";

    SerialAT.print(jsonBuffer);
  
    
    
}

modem.sendAT("+SMDISC");
if(modem.waitResponse(1000L,res) == 1)
{
Serial.println(res);
res="";
Serial.println("disconnectedf");

}   
  
res="";  

}
`

and this is the message that arrives on the topic on AWS

===================================================
AT+SMCONN
AT+SMPUB = "BasicPubSub", 425,0,0
AT+SMDISC
AT+SMCONN

AT+SMPUB = "BasicPubSub", 425,0,0

AT+SMDISC

AT+SMCONN

AT+SMPUB = "BasicPubSub", 425,0,0

AT+SMDISC

AT+SMCONN

AT+SMPUB = "BasicPubSub", 425,0,0

AT+SMDISC

AT+SMC

The payload just contains all the previous AT commands entered with the actual payload.
What is the mistake that I am doing ? What changes should I be making to the code?
