<p>Registering the "not found" handler is a different way than ESP8266WebServer (WebServer as ESP32). The <em>onNotFound</em> of ESP8266WebServer/WebServer does not work with AutoConnect. AutoConnect overrides <em>ESP8266WebServer::onNotFound</em>/<em>WebServer::onNotFound</em> to handle a captive portal. To register "not found" handler, use <a href="api.html#onnotfound"><em>AutoConnect::onNotFound</em></a>.</p>

<p>AutoConnect stores the established WiFi connection in the flash of the ESP8266/ESP32 module and equips the class to access it from the sketch. You can read, write or erase the credentials using this class individually. It's <a href="credit.html#autoconnectcredential">AutoConnectCredential</a> class which provides the access method to the saved credentials in the flash. Refer to section <a href="credit.html">Saved credentials access</a> for details.</p>

<p class="admonition-title">Where to store credentials in ESP32 with AutoConnect v1.0.0 or later</p>
|
|
<p>Since v1.0.0, credentials are stored in nvs of ESP32. AutoConnect v1.0.0 or later accesses the credentials area using the <strong>Preferences</strong> class with the arduino esp-32 core. So in ESP32, the credentials are not in the EEPROM, it is in the namespace <strong>AC_CREDT</strong> of the nvs. See <a href="credit.html">Saved credentials access</a> for details.<br />
|
|
In ESP8266, it is saved in EEPROM as is conventionally done.</p>

|
|
<p>When the captive portal is started, SoftAP starts and the STA is disconnected. The current SSID setting memorized in ESP8266 will be lost but then the reconnect behavior of ESP32 is somewhat different from this.</p>
|
|
<p>The <a href="https://github.com/espressif/arduino-esp32/blob/a0f0bd930cfd2d607bf3d3288f46e2d265dd2e11/libraries/WiFi/src/WiFiSTA.h#L46"><em>WiFiSTAClass::disconnect</em></a> function implemented in the arduino-esp32 has extended parameters than the ESP8266's arduino-core. The second parameter of WiFi.disconnect on the arduino-esp32 core that does not exist in the <a href="https://github.com/esp8266/Arduino/blob/7e1bdb225da8ab337373517e6a86a99432921a86/libraries/ESP8266WiFi/src/ESP8266WiFiSTA.cpp#L296">ESP8266WiFiSTAClass</a> has the effect of deleting the currently connected WiFi configuration and its default value is "false". On the ESP32 platform, even if WiFi.disconnect is executed, WiFi.begin() without the parameters in the next turn will try to connect to that AP. That is, automatic reconnection is implemented in arduino-esp32 already. Although this behavior appears seemingly competent, it is rather a disadvantage in scenes where you want to change the access point each time. When explicitly disconnecting WiFi from the Disconnect menu, AutoConnect will erase the AP connection settings saved by arduino-esp32 core. AutoConnect's automatic reconnection is a mechanism independent from the automatic reconnection of the arduino-esp32 core.</p>
|
|
<p>If the <a href="apiconfig.html#autoreconnect"><strong>autoReconnect</strong></a> option of the <a href="apiconfig.html">AutoConnectConfig</a> class is enabled, it automatically attempts to reconnect to the disconnected past access point. When the autoReconnect option is specified, AutoConnect will not start SoftAP immediately if the first WiFi.begin fails. It will scan WiFi signal and the same connection information as the detected BSSID is stored in the flash as AutoConnect's credentials, explicitly apply it with WiFi.begin and rerun.</p>

<p>AutoConnect has two parameters for timeout control. One is a timeout value used when trying to connect to the specified AP. It behaves the same as general timeout control in connection attempt by WiFi.begin. This control is specified by the third parameter of <a href="api.html#begin"><em>AutoConnect::begin</em></a>. The default value is macro defined by <a href="api.html#defined-macros"><strong>AUTOCONNECT_TIMEOUT</strong></a> in the <strong>AutoConnectDef.h</strong> file.</p>
|
|
<p>The other timeout control is for the captive portal itself. It is useful when you want to continue sketch execution with offline even if the WiFi connection is not possible. You can also combine it with the <a href="#on-demand-start-the-captive-portal"><strong>immediateStart</strong></a> option to create sketches with high mobility.</p>
|
|
<p>The timeout of the captive portal is specified together with <a href="apiconfig.html#portaltimeout"><em>AutoConnectConfig::portalTimeout</em></a> as follows.</p>

<p>There is another option related to timeout in AutoConnectConfig. It can make use of the captive portal function even after a timeout. The <a href="apiconfig.html#retainportal"><em>AutoConnectConfig::retainPortal</em></a> option will not stop the SoftAP when the captive portal is timed out. If you enable the ratainPortal option, you can try to connect to the AP at any time while continuing to sketch execution with offline even after the captive portal timed-out. Compared to the above code specified no option with the following example code, the captive portal will remain available even after a timeout without changing the logic of the sketch.</p>

<p>If your sketch handles web pages, you can embed the pages into the AutoConnect menu in continuance enjoying the utility of the WiFi connection feature. Unlike the custom Web pages by <a href="acelements.html">AutoConnectElements</a>, this allows to legacy web pages registered by <em>ESP8266WebServer::on</em> or <em>WebServer::on</em> function.</p>
|
|
<p>You can use AutoConnectAux only constructed with the URI of the page to be embedding. AutoConnectElements is not required. The basic procedure for this as follows:</p>
|
|
<ol>
|
|
<li>Declare AutoConnectAux for each legacy page. It includes the URI of the page and item string which will display in the AutoConnect menu.</li>
|
|
<li>Sketch the legacy page handlers.</li>

</blockquote>
|
|
<p>Also, in ESP32 arduino core 1.0.2 earlier, the placement of the EEPROM area of ESP32 is described in the <a href="https://github.com/espressif/arduino-esp32/blob/master/tools/partitions/default.csv">partition table</a>. So in the default state, the credential storage area used by AutoConnect conflicts with data owned by the user sketch. It will be destroyed together saved data in EEPROM by user sketch and AutoConnect each other. But you can move the storage area to avoid this.</p>
|
|
<p>The <a href="apiconfig.html#boundaryoffset"><strong>boundaryOffset</strong></a> in <a href="apiconfig.html">AutoConnectConfig</a> specifies the start offset of the credentials storage area. The default value is 0.</p>

<div class="admonition info">
|
|
<p class="admonition-title">The boundaryOffset ignored with AutoConnect v1.0.0 later on ESP32 arduino core 1.0.3 later</p>
|
|
<p>For ESP32 arduino core 1.0.3 and later, AutoConnect will store credentials to Preferences in the nvs. Since it is defined as the namespace dedicated to AutoConnect and separated from the area used for user sketches. Therefore, the boundaryOffet is ignored with the combination of AutoConnect v1.0.0 or later and the arduino-esp32 1.0.3 or later.</p>

<p>If you do not usually connect to WiFi and need to establish a WiFi connection if necessary, you can combine the <a href="apiconfig.html#autorise"><strong>autoRise</strong></a> option with the <a href="apiconfig.html#immediatestart"><strong>immediateStart</strong></a> option to achieve on-demand connection. This behavior is similar to the <a href="https://github.com/tzapu/WiFiManager#on-demand-configuration-portal">WiFiManager's startConfigPortal</a> function. In order to do this, you usually configure only with AutoConnectConfig in <em>setup()</em> and <a href="api.html#begin"><em>AutoConnect::begin</em></a> handles in <em>loop()</em>.</p>

<p>You can also assign no password to SoftAP launched as a captive portal. Assigning a null string as <code>String("")</code> to <a href="apiconfig.html#psk">AutoConnectConfig::psk</a> does not require a password when connecting to SoftAP.<br />
|
|
But this method is not recommended. The broadcast radio of SSID emitted from SoftAP will leak and reach several tens of meters.</p>

<ul>

<li>Short blink: The ESP module stays in APSTA mode.</li>
|

The default pin is arduino valiant's <strong>LED_BUILTIN</strong>.
