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

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.

WARNING :
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

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