GPS module with MKR GSM 1400

Hardware MKR Family MKRGSM1400

Is it possible to use GPS module with Arduino MKR GSM 1400?

I want to use Adafruit Ultimate GPS Breakout with Arduino MKR GSM 1400.

I want to obtain the coordinates and then send them through SMS.

Hmm,
Here is some code ive been testing with.

/*
 * GPS TEST
 * MKRGSM1400
 * SERCOM TEST (MAKE NEW SERIAL PORT)
 * 
 */
#include <Arduino.h>
/*

//NEW SERIAL

  Serial.begin(9600); //USB
  SerialGPS.begin(9600); //TEST GPS.

  while(!Serial) { ; } //WAIT FOR SERIAL USB.
  Serial.print("\nTEST SOMETHING\n\n");
  
}

#define CHECK_INTERVAL 5  //seconds.
unsigned long previousTest;
bool mGPS_got_line = false, mGPS_paused = false;
uint8_t mGPS_idx=0;
char mGPS_TempLine[120];

void loop() {

if (millis() - previousTest >= CHECK_INTERVAL*1000UL) 
{
  previousTest = millis();
  Serial.print("\n\nGET NEW LINE\n\n");
  if (mGPS_paused) mGPS_paused = false; 
}
char mGPS = 0;
if ((SerialGPS.available() > 0) && !mGPS_got_line && !mGPS_paused) 
{
  mGPS = SerialGPS.read();
  //Serial.write(mGPS);   //DEBUG
  if (mGPS == '\n') 
  {
    mGPS_TempLine[mGPS_idx] = 0; mGPS_idx = 0; mGPS_got_line = true;
  } 
  else
  {
     mGPS_TempLine[mGPS_idx++] = mGPS;
     if (mGPS_idx >= 120) mGPS_idx = 119;
  }
}
if (mGPS_got_line)
{
  if (strstr(mGPS_TempLine, "$GPRMC"))
  {
    Serial.print("-->");Serial.println(mGPS_TempLine);
    //DO SOMETHING WITH THE LINE.
    
    //done parsed.
    mGPS_paused = true; mGPS_got_line = false; //Reset to get a new after paused has been reset.
  }
  else
  {
    mGPS_got_line = false; //wrong line not GPRMC. get another.
  }
}

} //END LOOP

Any news with this configuration?

Yes it works fine.
(doesnt do much but, it reads gpsmodule, skip until it finds a string with GPRMC and display it in serialmonitor. wait x seconds and repeat.)

Just ignore the Sercom part in the code. its commented out already.

Hook up you GPS-module with the RX/TX pins and you should recieve GPRMC Lines.

Can you read GPS data using by mobile GSM and SMS txt messages?

I suggest you check out the examples in MKRGSM library.
Those functions are included there.

Hello, I am working on a project based on MKR1400 but I need to add BLE and GPS, is this possible?

what modules should i buy?

I will appreciate any help!!!
