Hardware Setup:

–Espresso Lite V2.0	–USB to UART Converter
–DHT22 Temperature and Humidity Sensor	–I2C Oled Module – Blue

GETTING STARTED

Step 1

Connect to the Internet by using AP mode(access point) method.

Step2

Assemble the Oled screen to the Espresso Lite v2.0 at 3v3,GND, SCL and SDA as the picture show:

Step 3

Press the button of GPIO13 for a few second until the Espresso Lite v2.0 restart, to switch the mode to the AP mode.

Long blinks: SmartConfig mode
No flash: Connected to Wi-Fi
Short blinks : AP mode
Normal blink: Trying to connect to Wi-Fi
No flash: Not connected to Wi-Fi

Step 4

The Espresso Lite v2.0 is now as an access point, so connect your laptop to the access point. The SSID shown on the OLED screen is decimal, however the SSID of the access point is shown in hexadecimals, so you will need to enter the SSID on the OLED screen into a hexadecimal to decimal converter to find the correct access point to connect to on your laptop.

Step 5

Open Internet browser and insert the IP address 192.168.4.1

Step 6

A box will appear, choose one of the Wifi network and press Enter.

Note: **After pressing Enter, press the button GPIO13 till the Oled screen reset. If the Espresso Lite v2.0 not connected please repeat the step or choose other networks.

Step 7

When the Oled screen show “Success”, that means the network is connected to your device.

Getting Started Espresso Lite v2.0 with Arduino IDE

Step 1

Install or update Arduino IDE v1.6.8

Step 2

Click on file->Prefereces->Settings->Additional Boards Manager URLs

Step 3

Copy this link: http://arduino.esp8266.com/stable/package_esp8266com_index.json into the columns of Additional Boards Manager URLs and click “OK”.

Step 4

Next,click on Tools->Board->Boards Manager,install the esp8266 by ESP8266 Community latest version.

Step 5

After install, again go to the board and click on Espresso Lite v2.0.

Step 6

After that, go to Sketch->Include Library->Manage Library, search the Library below and install it.

ESPert by Jimmy (current version 1.1.5)
Adafruit NeoPixel by Adafruit (current version 1.0.4)
ArduinoJson by Benoit Blanchon (current version 5.1.1)
DHT sensor library by Adafruit (current version 1.2.3)
ESP8266 Oled Driver for SSD1306 display by Daniel Eichborn (current version 2.0.0)
HttpClient by Adrian McEwen (current version 2.2.0)
PubSubClient by Nick O’Leary (current version 2.6.0)

Note: **Make sure you have installed the LATEST version for these libraries!

Or you can install it from github,click the link of each library to download the zip file.

How to install library from github manually?

Step 1

Download the zip file library from github and save to a folder.

Step 2

Go to Sketch->Include Library->Add.ZIP Library

Step 3

Select your zip file and open it.So the library will install in your Arduino IDE 1.6.8.

You may try other example.

Have Fun!

Hi, the error is “Adafruit_Sensor.h: No such file or directory”. I’m not sure why they separating this library. However you can download Adafruit_Sensor.h here and put it inside your Arduino libraries folder. Thanks.
