#include <HardwareSerial.h>

HardwareSerial gpsSerial(1); // Use UART1 for GPS communication

void setup() {
  // Initialize Serial Monitor
  Serial.begin(115200);
  while (!Serial) {
    ; // Wait for Serial to be ready
  }
  Serial.println("Serial Monitor started");

  // Initialize GPS Serial
  gpsSerial.begin(9600, SERIAL_8N1, 16, 17); // RX=16, TX=17
  Serial.println("GPS Serial started");
}

void loop() {
  // Check if data is available from GPS module
  if (gpsSerial.available()) {
    // Read data from GPS module
    while (gpsSerial.available()) {
      char c = gpsSerial.read();
      Serial.print(c); // Print GPS data to Serial Monitor
    }
  }
}

This code initializes the serial communication for both the Serial Monitor and the GPS module. It continuously reads data from the GPS module and prints it to the Serial Monitor.
