Connecting to AWS using GPRS

[mazeemsk]

Hi,
I want to use this library to connect to AWS using SIM800L GPRS module.My code connected to internet but does not connect to AWS...kindly guide as I am a newbie. here is my code.

#define TINY_GSM_MODEM_SIM800
#include <SoftwareSerial.h>
#include <TinyGsmClient.h>
#include <PubSubClient.h>

//Enter values in secrets.h ▼

#include "secrets.h"

SoftwareSerial SerialAT(16,17); // RX, TX


//Network details
const char apn[]  = "";
const char user[] = "";
const char password[] = "";

const int  MQTT_PORT = 8883;
const char MQTT_SUB_TOPIC[] = "$aws/things/" THINGNAME "/shadow/update";
const char MQTT_PUB_TOPIC[] = "$aws/things/" THINGNAME "/shadow/update";


TinyGsm modem(SerialAT);
//TinyGsmClient client(modem);
TinyGsmClientSecure client(modem);
PubSubClient mqtt(client);

void setup()
{
  Serial.begin(9600);
  SerialAT.begin(9600);
  
  Serial.println("System start.");
  modem.restart();
  Serial.println("Modem: " + modem.getModemInfo());
  Serial.println("Searching for telco provider.");
  if(!modem.waitForNetwork())
  {
    Serial.println("fail");
    while(true);
  }
  Serial.println("Connected to telco.");
  Serial.println("Signal Quality: " + String(modem.getSignalQuality()));

  Serial.println("Connecting to GPRS network.");
  if (!modem.gprsConnect(apn, user, password))
  {
    Serial.println("fail");
    while(true);
  }
  Serial.println("Connected to GPRS: " + String(apn));
  
  
  mqtt.setServer(MQTT_HOST, MQTT_PORT);
  mqtt.setCallback(mqttCallback);
  Serial.println("Connecting to MQTT Broker: " + String(MQTT_HOST));
  while(mqttConnect()==false) continue;
  Serial.println();
  
  
  
    
}

void loop()
{
  if(Serial.available())
  {
    delay(10);
    String message="";
    while(Serial.available()) message+=(char)Serial.read();
    mqtt.publish(MQTT_PUB_TOPIC, message.c_str());
  }
  
  if(mqtt.connected())
  {
    mqtt.loop();
  }
}

boolean mqttConnect()
{
  if(!mqtt.connect("GsmClientTest"))
  {
    Serial.print(".");
    return false;
  }
  Serial.println("Connected to broker.");
  mqtt.subscribe(MQTT_SUB_TOPIC);
  return mqtt.connected();
}
