ARDUINO: How to send GPS data to Firebase? - arduino

Question

I have a UBLOX Neo 6M Module to get the latitude and longitude of a device. I am planning to send these data to Firebase. From my research, it requires a Wifi Module for it to be able to pass the data to Firebase. I was planning to use a SIM card that may provide internet data.
#include <FirebaseArduino.h>
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
#define FIREBASE_HOST "FIREBASE URL"
#define FIREBASE_AUTH "DB SECRET"
//SIM
#define APN "internet"
void setup() {
Serial.begin(9600);
ss.begin(GPSBaud);
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}
int n = 0;
void loop(){
// This sketch displays information every time a new sentence is correctly encoded.
while (ss.available() > 0){
gps.encode(ss.read());
if (gps.location.isUpdated()){
Serial.print("Latitude= ");
Serial.print(gps.location.lat(), 6);
Serial.print(" Longitude= ");
Serial.println(gps.location.lng(), 6);
}
}
}
delay(1000);
// set bool value
Firebase.setBool("truth", false);
// handle error
if (Firebase.failed()) {
Serial.print("setting /truth failed:");
Serial.println(Firebase.error());
return;
}
delay(1000);
// append a new value to /logs
String name = Firebase.push("location", gps);
// handle error
if (Firebase.failed()) {
Serial.print("pushing /location failed:");
Serial.println(Firebase.error());
return;
}
Serial.print("pushed: /location/");
Serial.println(name);
delay(1000);
}

I'm sure that this code block wont lead me to a working system. But what I want to know if this sequence may lead me to somewhere. Please drop ideas on what I lack and I should search. Thank you.

I'm not sure about how Firebase works but what you need to do is to first get a valid location and then pass it to Firebase, something like this:
#include <FirebaseArduino.h>
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
#define FIREBASE_HOST "FIREBASE URL"
#define FIREBASE_AUTH "DB SECRET"
//SIM
#define APN "internet"
float lat, lng;
// The TinyGPS++ object
TinyGPSPlus gps;
// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);
void setup()
{
Serial.begin(9600);
ss.begin(GPSBaud);
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
unsigned long last_millis = millis();
}
void feed_gps()
{
unsigned long last_millis = millis();
if (ss.available() > 0)
{
//feed gps for 1 seconds
while (millis() - last_millis < 1000)
{
gps.encode(ss.read());
if (gps.location.isValid())
{
lat = gps.location.lat();
lng = gps.location.lng();
Serial.print("Latitude= ");
Serial.print(lat, 6);
Serial.print(" Longitude= ");
Serial.println(lng, 6);
}
else
{
Serial.print("GPS still unavailable, Chars processed: ");
Serial.println(gps.charsProcessed());
}
}
}
}
void loop()
{
feed_gps();
// set bool value
Firebase.setBool("truth", false);
// handle error
if (Firebase.failed())
{
Serial.print("setting /truth failed:");
Serial.println(Firebase.error());
return;
}
char location_str[25] = {0};
// store string of lat,lng
sprintf(location_str, "%f, %f", lat, lng);
String name = Firebase.push("location", location_str);
// handle error
if (Firebase.failed())
{
Serial.print("pushing /location failed:");
Serial.println(Firebase.error());
return;
}
Serial.print("pushed: /location/");
Serial.println(name);
}
