newbie question

[ahmedjamion]

Hello, does anyone have a example project using this library? I'm trying to send sensor data to firebase and just can't get it right. thanks in advance

You should read the documentation thoroughly for understanding the concept and basic usage.
https://github.com/mobizt/FirebaseClient

The examples are here.

wow thanks alot for responding, can you take a look at my code? i am very noob at coding i was using your other library but im having trouble getting data from firebase it always says "response payload read timed out" or something.
here is my void setup and loop:
void setup() {
// SERIAL MONITOR SET UP
Serial.begin(115200);

// PARKING SPACE IR SENSORS SET UP
pinMode(irPinP1, INPUT);
pinMode(irPinP2, INPUT);
pinMode(irPinP3, INPUT);

// PARKING SPACE #1 LEDS SET UP
pinMode(p1Red, OUTPUT);
pinMode(p1Green, OUTPUT);
pinMode(p1Blue, OUTPUT);

// PARKING SPACE #2 LEDS SET UP
pinMode(p2Red, OUTPUT);
pinMode(p2Green, OUTPUT);
pinMode(p2Blue, OUTPUT);

// PARKING SPACE #3 LEDS SET UP
pinMode(p3Red, OUTPUT);
pinMode(p3Green, OUTPUT);
pinMode(p3Blue, OUTPUT);

// GATE IRS SET UP
pinMode(irPinEntry, INPUT);
pinMode(irPinExit, INPUT);

// GATE SERVOS SET UP
servoEntry.attach(servoPinEntry);
servoExit.attach(servoPinExit);

// LCD SET UP
lcd.init();
lcd.backlight();

initWiFi();

Firebase.printf("Firebase Client v%s\n", FIREBASE_CLIENT_VERSION);
Serial.println("Initializing app...");

ssl_client.setInsecure();

app.setCallback(asyncCB);

initializeApp(aClient, app, getAuth(user_auth));

ms = millis();
while(app.isInitialized() && !app.ready() && millis() - ms < 120 * 1000);

app.getApp(Database);

Database.url(DATABASE_URL);
}

void loop() {

app.loop();
Database.loop();

// READ GATE SENSORS
if (app.ready()){
entryGateSensor = digitalRead(irPinEntry);
exitGateSensor = digitalRead(irPinExit);

if (entryGateSensor == LOW) {
entryStatus == "LOW";
Database.set(aClient, "/IoTEnabledParking/gateSensors/entry/status", "LOW", asyncCB);
} else if (entryGateSensor == HIGH) {
entryStatus == "HIGH";
Database.set(aClient, "/IoTEnabledParking/gateSensors/entry/status", "HIGH", asyncCB);
}
}

// READ PARKING SENSORS
p1Sensor = digitalRead(irPinP1);
p2Sensor = digitalRead(irPinP2);
p3Sensor = digitalRead(irPinP3);

p1Status = (p1Sensor == LOW) ? "OCCUPIED" : "VACANT";
p2Status = (p2Sensor == LOW) ? "OCCUPIED" : "VACANT";
p3Status = (p3Sensor == LOW) ? "OCCUPIED" : "VACANT";

if(entryGateSensor == LOW) {
servoEntry.write(10);
} else {
servoEntry.write(100);
}

if(exitGateSensor == LOW) {
servoExit.write(10);
}else {
servoExit.write(110);
}

delay(1000);
}

// CONNECT TO WIFI
void initWiFi() {
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);

Serial.print("Connecting to WiFi ..");

while (WiFi.status() != WL_CONNECTED) {
Serial.print('.');
delay(1000);
}

Serial.println();
Serial.print("Connected to: ");
Serial.println(WiFi.localIP());
}

void asyncCB(AsyncResult &aResult)
{

// To get the UID (string) from async result
// aResult.uid();

printResult(aResult);

}

void printResult(AsyncResult &aResult)
{
if (aResult.appEvent().code() > 0)
{
Firebase.printf("Event msg: %s, code: %d\n", aResult.appEvent().message().c_str(), aResult.appEvent().code());
}

if (aResult.isDebug())
{
    Firebase.printf("Debug msg: %s\n", aResult.debug().c_str());
}

if (aResult.isError())
{
    Firebase.printf("Error msg: %s, code: %d\n", aResult.error().message().c_str(), aResult.error().code());
}

if (aResult.available())
{
    Firebase.printf("payload: %s\n", aResult.c_str());
}

}
hope you can take a look at this, thank you very much

Error msg: operation was cancelled, code: -118
Error msg: operation was cancelled, code: -118
Error msg: operation was cancelled, code: -118
Error msg: operation was cancelled, code: -118
payload: "HIGH"

Error msg: operation was cancelled, code: -118
Error msg: operation was cancelled, code: -118

this is what the serial monitor shows, and on my firebase console it's not updating

The async queue is full because you use delay in the loop and all async task is running slowly because of your delay.
https://github.com/mobizt/FirebaseClient?tab=readme-ov-file#async-queue

You have to read the documentation thoroughly.

Everything you should know is in the documentation.

[mobizt]

You are using async library then you should remove all delay codes from the loop().
https://github.com/mobizt/FirebaseClient?tab=readme-ov-file#async-queue

im still getting this error after removing the delay(1000);

If you don't know how to use async library properly and don't know how async concept works, use sync function instead.
https://github.com/mobizt/FirebaseClient/tree/main/examples/RealtimeDatabase/Sync

[mobizt]

Are you sure? Look at the delay(1000) from code you post above.

[ahmedjamion]

yes sir, thanks for the advice, thats for sure, kinda have to rush for now because of this school project, hopefully i can make things work at least,

[ahmedjamion]

sorry, im a bit confused, do i need to get rid of delays everywhere in my code?

[mobizt]

I told you about delay in loop().

You should post such basic programming question in community forum instead.

Your problem is lack of basic Arduino programming skills not a library issue.

[ahmedjamion]

I'm really sorry sir for this mistake sir, you can just remove my question, sorry to bother, i didnt mean to say that there is problem in the library, i knew that i was definitely doing something wrong so i tried to ask a question, im sorry if its in the wrong place sir. hope your not mad, apologies.
