Here the basic usage example of array. FirebaseData fbdo;
FirebaseJsonArray arr; // you can add or set the array data
arr.add(123); //index 0
arr.add(true);
arr.add("test");
arr.add(456.789); //index 3
//arr.set("/[5]", "hello"); //index 5 assigned with path, now index 4 which never assigned will be null value.
//arr.set(7, 999); //index 7 assigned with number, now index 6 will be null value.
//arr.set("/[8]/car/[2]/xyz", true); //index 8 assigned with nested array and json object inside.
if (Firebase.setArray(fbdo, "path/to/node", arr)) //or Firebase.set(fbdo, "path/to/node", arr)
{
Seril.println("set array ok");
}else{
Seril.println("set array failed");
Seril.println(fbdo.errorReason());
}
if (Firebase.getArray(fbdo, "path/to/node")) // or Firebase.get(fbdo, "path/to/node"))
{
Seril.println("get array ok");
printResult(fbdo); //See https://github.com/mobizt/Firebase-ESP8266/blob/f902eca7a8cc09977880058575e4f12030d1575e/src/addons/RTDBHelper.h#L20
}else{
Seril.println("get array failed");
Seril.println(fbdo.errorReason());
}

You should post your code or data structure and describe what you're trying to do and what's the expected result. |

this is my code, cmiiw.. Email: [email protected] Github: https://github.com/mobizt Copyright (c) 2021 mobizt */ #if defined(ESP32) //Provide the token generation process info. /* 1. Define the WiFi credentials */ /* 2. Define the API Key */ /* 3. Define the RTDB URL */ /* 4.

This is my code for sending an array: FirebaseJsonArray ARR; //declare the jsonarray first and then, this is my full code : #include <FirebaseESP8266.h> #define WIFI_SSID "Wlingi 33" //your WiFi SSID for which yout NodeMCU connects #define TRIG_PIN D4 // Declare the Firebase Data object in the global scope // Declare global variable to store value void setup() { Serial.begin(9600); // Select the same baud rate if you want to see the datas on Serial Monitor Firebase.reconnectWiFi(true); void loop() { val = distanceSensor.measureDistanceCm(); for(x=0 ; x < parity_count ; x++) for(x=0; x<((sizeof(EN)/sizeof(EN[0]))-1); x++){ } for some reason on my nodeMCU, only these version will work with that code Arduino ver 1.8.9, ESP8266 WiFi ver 2.5.0, FirebaseESP8266 ver 2.6.0 |
