HELP

[semenesp32]

@mobizt Hello, I'm trying to work with your new Firesbase-ESP32 library. I tried to create a new file using your library, but I got errors when compiling the file. I'm using a WEMOS LOLI32 board, Arduino ide version 1.8.5. File code:

include

include

include "DHTesp.h"

include

define DHTpin 15

DHTesp dht;

char buff[10];

define FIREBASE_HOST "https://esp32andfirebase.firebaseio.com/"

define FIREBASE_AUTH "gga1JXWY5rgyBHk56RSXLn3FPpajWfcq6itIM3nI"

define WIFI_SSID "fawadkhan"

define WIFI_PASSWORD "fawadkhan12"

//Define FirebaseESP32 data object FirebaseData firebaseData; FirebaseJson json;

String mytemp; String myhum; void setup() {

Serial.begin(115200); dht.setup(DHTpin, DHTesp::DHT11); 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();

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); Firebase.reconnectWiFi(true);

//Set database read timeout to 1 minute (max 15 minutes) Firebase.setReadTimeout(firebaseData, 1000 * 60); //tiny, small, medium, large and unlimited. //Size and its write timeout e.g. tiny (1s), small (10s), medium (30s) and large (60s). Firebase.setwriteSizeLimit(firebaseData, "tiny");

Serial.println("------------------------------------");

Serial.println("Connected..."); }

void loop() { delay(dht.getMinimumSamplingPeriod());

float humidity = dht.getHumidity(); float temperature = dht.getTemperature(); myhum = dtostrf(humidity,3,2,buff); mytemp = dtostrf(temperature,3,2,buff); Serial.println(myhum); Serial.println(mytemp);

delay(100); json.set("/hum", myhum); json.set("/temp", mytemp); Firebase.updateNode(firebaseData,"/Sensor",json); }

I would appreciate your help.

The library installation problem.

Please delete the library from the libraries folder and install again.

[mobizt]

When you get the compilation error, you should post all errors instead of some part.

Look like you are not yet install ESP32 core SDK or incomplete install or out dated.

Please install the latest Arduino ESP32 Core SDK.

I have updated the ESP32 Core SDK. Everything worked. Thank you very much for your help.
