TFMini S no output on Arduino Mega

Using Arduino Sensors

Hello! I'm encountering a problem obtaining data from TFMini S using Arduino Mega. The code is running but shows no output on the serial monitor. I have tried using different pins but the outputs are still not showing.

#include <SoftwareSerial.h>
#include "TFMini.h"

// Setup software serial port
SoftwareSerial mySerial(18, 19);  // Uno RX (TFMINI TX), Uno TX (TFMINI RX)
TFMini tfmini;

void setup() {
  // Step 1: Initialize hardware serial port (serial debug port)
  Serial.begin(115200);
  // wait for serial port to connect. Needed for native USB port only
  while (!Serial)
    ;

  Serial.println("Initializing...");

  // Step 2: Initialize the data rate for the SoftwareSerial port
  mySerial.begin(TFMINI_BAUDRATE);

  // Step 3: Initialize the TF Mini sensor
  tfmini.begin(&mySerial);
}


void loop() {
  // Take one TF Mini distance measurement
  uint16_t dist = tfmini.getDistance();
  uint16_t strength = tfmini.getRecentSignalStrength();

  // Display the measurement
  Serial.print(dist);
  Serial.print(" cm      sigstr: ");
  Serial.println(strength);

  // Wait some short time before taking the next measurement
  delay(25);
}

The code is an example from the TFmini library.

TFMini_BAUDRATE is 115200. Last I checked SoftwareSerial isn't that fast.

 // Step 2: Initialize the data rate for the SoftwareSerial port
  mySerial.begin(TFMINI_BAUDRATE);

It's a Mega, right? Use hardware Serial1. It will do 115200 baud.
