I am getting error on Serial monitor Soft WDT reset. I decoded the error code also and found the following stacktrace.

I am using SIM808 module and DFRobot_sim808 as the library.

I tried to find solution for the same everywhere but none found it. But the same code I am trying on arduino it works but not for ESP8266. I dont have long waiting loop(). But still it gives me error.

Below is the code for the same

#include <DFRobot_sim808.h>
#include <SoftwareSerial.h>
#define PHONE_NUMBER "********" 
#define MESSAGE "hello,world"
#define PIN_TX D1 
#define PIN_RX D0
SoftwareSerial mySerial(PIN_RX, PIN_TX);
DFRobot_SIM808 sim808(&mySerial);//Connect RX,TX,PWR,
void setup() {
 delay(1000);
 mySerial.begin(9600);
 Serial.begin(9600);
 while (!Serial) {
 ; // wait for serial port to connect. Needed for native USB
 }
 while(!sim808.init()) {
 delay(1000);
 Serial.print("Sim808 init error\r\n");
 } 
 Serial.println("Sim808 init success");
 Serial.println("Start to send message ...");
 sim808.sendSMS(PHONE_NUMBER,MESSAGE);
}
void loop() {
}
