Hello, can anyone help me to solve the problem with my project, namely Esp32 and Gps Neo 6m Firebase?
Following Programs:
#include <FirebaseESP32.h>
#include <WiFi.h>
#include <HardwareSerial.h>
#include <TinyGPS++.h>
#define FIREBASE_HOST ""
#define FIREBASE_AUTH ""
#define WIFI_SSID ""
#define WIFI_PASSWORD ""
FirebaseData firebaseData;
FirebaseJson json;
const int RXPin = 5; // D5 on ESP32
const int TXPin = 4; // D4 on ESP32
HardwareSerial neo6m(1); // Use Serial1 for ESP32
TinyGPSPlus gps;
void setup() {
Serial.begin(115200);
neo6m.begin(9600, SERIAL_8N1, RXPin, TXPin);
wifiConnect();
Serial.println("Connecting Firebase.....");
Firebase.reconnectWiFi(true);
Serial.println("Firebase OK.");
}
void loop() {
smartdelay_gps(1000);
if (gps.location.isValid()) {
float latitude = gps.location.lat();
float longitude = gps.location.lng();
if (Firebase.setFloat(firebaseData, "/GPS/f_latitude", latitude)) {
print_ok();
} else {
print_fail();
}
if (Firebase.setFloat(firebaseData, "/GPS/f_longitude", longitude)) {
print_ok();
} else {
print_fail();
}
} else {
Serial.println("No valid GPS data found.");
}
delay(10000);
}
static void smartdelay_gps(unsigned long ms) {
unsigned long start = millis();
do {
while (neo6m.available()) {
gps.encode(neo6m.read());
}
} while (millis() - start < 3000);
}
void wifiConnect() {
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("Connecting to Wi-Fi");
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(300);
}
Serial.println();
Serial.print("Connected with IP: ");
Serial.println(WiFi.localIP());
Serial.println();
}
void print_ok() {
Serial.println("------------------------------------");
Serial.println("OK");
Serial.println("PATH: " + firebaseData.dataPath());
Serial.println("TYPE: " + firebaseData.dataType());
Serial.println("ETag: " + firebaseData.ETag());
Serial.println("------------------------------------");
Serial.println();
}
void print_fail() {
Serial.println("------------------------------------");
Serial.println("FAILED");
Serial.println("REASON: " + firebaseData.errorReason());
Serial.println("------------------------------------");
Serial.println();
}
