# AutoConnect <small>for ESP8266</small>

An Arduino library for ESP8266 WLAN configuration at run time with web interface.

## Overview

To the dynamic configuration for joining to WLAN with SSID and PSK accordingly. It an Arduino library united with *ESP8266WebServer* class.
Easily implementing the Web interface constituting the WLAN for ESP8266 WiFi connection. With this library to make a sketch easily which connects from ESP8266 to the access point at runtime by the web interface without hard-coded SSID and password.

### <i class="fa fa-arrow-circle-right" aria-hidden="true"></i> No need pre-coded SSID &amp; password

<span class="lead">It is no needed hard-coding in advance the SSID and Password into the sketch to connect between ESP8266 and WLAN. You can input SSID &amp; Password from a smartphone via the web interface at runtime.</span>

### <i class="fa fa-arrow-circle-right" aria-hidden="true"></i> Simple usage

<span class="lead">AutoConnect control screen will be displayed automatically for establishing new connections. It aids by the <a href="https://en.wikipedia.org/wiki/Captive_portal">captive portal</a> when vested the connection cannot be detected.<br>By using the [AutoConnect menu](menu.md), to manage the connections convenient.</span>

### <i class="fa fa-arrow-circle-right" aria-hidden="true"></i> Store the established connection

<span class="lead">The connection authentication data as credentials are saved automatically in EEPROM of ESP8266 and You can select the past SSID from the [AutoConnect menu](menu.md).</span>

### <i class="fa fa-arrow-circle-right" aria-hidden="true"></i> Easy to embed in

<span class="lead">AutoConnect can be embedded easily into your sketch, just "**begin**" and "**handleClient**".</span>

### <i class="fa fa-arrow-circle-right" aria-hidden="true"></i> Lives with the your sketches

<span class="lead">The sketches which provide the web page using ESP8266WebServer there is, AutoConnect will not disturb it. AutoConnect can use an already instantiated ESP8266WebServer object, or itself can assign it.</span>

## Installation

### Requirements

#### Supported hardware

  * [X] Generic ESP8266 modules (applying the ESP8266 Community's Arduino core)
  * [X] Adafruit HUZZAH ESP8266 (ESP-12)
  * [X] ESP-WROOM-02
  * [X] Heltec WiFi Kit 8
  * [X] NodeMCU 0.9 (ESP-12) / NodeMCU 1.0 (ESP-12E)
  * [X] Olimex MOD-WIFI-ESP8266
  * [X] SparkFun Thing
  * [X] SweetPea ESP-210

!!! info "About flash size on the module"
    The AutoConnect sketch size is relatively large. Large flash capacity is necessary. 512Kbyte (4Mbits) flash inclusion module such as ESP-01 is not recommended.

#### Required libraries

AutoConnect requires the following environment and libraries.

<i class="fa fa-download"></i> <strong>Arduino IDE</strong>

The current upstream at the 1.8 level or later is needed. Please install from the [official Arduino IDE download page](https://www.arduino.cc/en/Main/Software). This step is not required if you already have a modern version.

<i class="fa fa-download"></i> <strong>ESP8266 Arduino core</strong>

AutoConnect targets sketches made on the assumption of [ESP8266 Community's Arduino core](https://github.com/esp8266/Arduino). The [latest release](https://github.com/esp8266/Arduino/releases/latest) is recommended.  
Install third-party platform using the *Boards Manager* of Arduino IDE. Package URL is http://arduino.esp8266.com/stable/package_esp8266com_index.json

<i class="fa fa-download"></i> <strong>Additional necessary library</strong>

The [PageBuilder](https://github.com/Hieromon/PageBuilder) library to build HTML for ESP8266WebServer is needed.  
To install the PageBuilder library into your Arduino IDE, you can use the *Library Manager*. Select the board of ESP8266 series in the Arduino IDE, open the library manager and search keyword '**pagebuilder**' in the topic '**Communication**', then you can see the *PageBuilder*. The latest version or 1.0.0 later is required.

### Install the AutoConnect

Clone or download from the [AutoConnect GitHub repository](https://github.com/Hieromon/AutoConnect).

<img src="./images/gitrepo.png" width="640"/>

When you select Download, you can import it to Arduino IDE immediately. After downloaded, the AutoConnect-master.zip file will be saved in your download folder. Then in the Arduino IDE, navigate to *"Sketch > Include Library"*. At the top of the drop down list, select the option to *"Add .ZIP Library..."*. Details for [Arduino official page](https://www.arduino.cc/en/Guide/Libraries#toc4).
