DHT11 Sensor with bluetooth and arduino nano

Hey there guys, I have an issue with my project I mean I can upload to the board, because it seems that I don鈥檛 have the whole libraries, but I recently downloaded them. So please help me.
This is the code, I got it from the sketch browser of blynk.

this is the code :thinking:

Download latest Blynk library here:
Release v1.3.2 路 blynkkk/blynk-library 路 GitHub

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

Downloads, docs, tutorials: http://www.blynk.cc
Sketch generator:           http://examples.blynk.cc
Blynk community:            http://community.blynk.cc
Follow us:                  http://www.fb.com/blynkapp

Blynk library is licensed under MIT license
This example code is in public domain.

Note: This only works on Android!
iOS does not support Bluetooth 2.0 Serial Port Profile
You may need to pair the module with your smartphone
via Bluetooth settings. Default pairing password is 1234

Feel free to apply it to any other example. It鈥檚 simple!

NOTE: Bluetooth support is in beta!

This example shows how value can be pushed from Arduino to
the Blynk App.

For this example you鈥檒l need Adafruit DHT sensor libraries:
GitHub - adafruit/Adafruit_Sensor: Common sensor library
GitHub - adafruit/DHT-sensor-library: Arduino library for DHT11, DHT22, etc Temperature & Humidity Sensors

App project setup:
Value Display widget attached to V5
Value Display widget attached to V6

#define BLYNK_PRINT Serial

#include <SoftwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX

#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>
#include <DHT.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = 鈥26dee6e492b847969383c9587f9d499d鈥;

SoftwareSerial SerialBLE(0, 1); // RX, TX

#define DHTPIN 2 // What digital pin we鈥檙e connected to

// Uncomment whatever type you鈥檙e using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22, AM2302, AM2321
//#define DHTTYPE DHT21 // DHT 21, AM2301

BlynkTimer timer;

// This function sends Arduino鈥檚 up time every second to Virtual Pin (5).
// In the app, Widget鈥檚 reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void sendSensor()
float h = dht.readHumidity();
float t = dht.readTemperature(); // or dht.readTemperature(true) for Fahrenheit

if (isnan(h) || isnan(t)) {
Serial.println(鈥淔ailed to read from DHT sensor!鈥);
// You can send any value at any time.
// Please don鈥檛 send more that 10 values per second.
Blynk.virtualWrite(V5, h);
Blynk.virtualWrite(V6, t);

void setup()
// Debug console

Blynk.begin(SerialBLE, auth);

Serial.println(鈥淲aiting for connections鈥︹);


// Setup a function to be called every second
timer.setInterval(1000L, sendSensor);

void loop()

hey Lise,
I think it comes from the version of your IDE, try to execute desktop version.
