<p>Several parameters as follows of <a href="apiconfig.html">AutoConnectConfig</a> affect the behavior of <a href="api.html#begin">AutoConnect::begin</a> function. Each parameter affects the behaves in interacted order with the priority and apply to the logic sequence of AutoConnect::begin.</p>
<ul>
<li><a href="apiconfig.html#immediatestart">immediateStart</a> : The captive portal start immediately, without first WiFi.begin.</li>
<li><a href="apiconfig.html#autoreconnect">autoReconenct</a> : Attempt re-connect with past SSID by saved credential.</li>
<li><a href="apiconfig.html#portaltimeout">portalTimeout</a> : Time out limit for the portal.</li>
<li><a href="apiconfig.html#retainportal">retainPortal</a> : Keep DNS server functioning for the captive portal.</li>
</ul>
<p>You can use these parameters in combination with sketch requirements and need to understand correctly the behavior caused by the parameters. The following chart shows the AutoConnect::begin logic sequence including the effect of these parameters.</p>
<p><img align="center" src="images/process_begin.svg"></p>
<p>For example, AutoConnect::begin will not exits without the <strong>portalTimeout</strong> while the connection not establishes, but WebServer will start to work. So, your sketch may work seemingly, but it will close with inside a loop of the AutoConnect::begin function. Especially when invoking AutoConnect::begin in the <strong>setup()</strong>, execution control does not pass to the <strong>loop()</strong>.</p>
<p>As different scenes, you may use the <strong>immediateStart</strong> effectively. Equipped the external switch to activate the captive portal with the ESP module, combined with the <strong>portalTime</strong> and the <strong>retainPortal</strong> it will become WiFi active connection feature. You can start AutoConnect::begin at any point in the <strong>loop()</strong>, which allows your sketch can behave both the offline mode and the online mode.</p>
<p>Please consider these kinds of influence when you make sketches.</p>
<div class="admonition info">
<p class="admonition-title">The AutoConnect::begin 3<sup>rd</sup> parameter</p>
<p>Another parameter as the <a href="api.html#begin">3<sup>rd</sup> parameter</a> of AutoConnect::begin related to timeout constrains the connection wait time after WiFi.begin. It is the <strong>CONNECTED</strong> judgment of the above chart that it has an effect.</p>
