  458. <p>Custom Web page processing consumes a lot of memory. AutoConnect will take a whole string of the JSON document for the custom Web pages into memory. The required buffer size for the JSON document of example sketch <em>mqttRSSI</em> reaches approximately 3000 bytes. And actually, it needs twice the heap area. Especially this constraint will be a problem with the ESP8266 which has a heap size poor.</p>
  459. <p>AutoConnect can handle custom Web pages without using JSON. In that case, since the ArduinoJson library will not be bound, the Sketch size will also be reduced.</p>

  461. <p>To handle the custom Web pages without using JSON, follow the steps below.</p>
  462. <ol>
  463. <li>Create or define <a href="apiaux.html">AutoConnectAux</a> for each page.</li>
  464. <li>Create or define <a href="acelements.html">AutoConnectElement(s)</a>.</li>
  465. <li>Add <a href="acelements.html">AutoConnectElement(s)</a> to AutoConnectAux.</li>
  466. <li>Create more AutoConnectAux containing <a href="acelements.html">AutoConnectElement(s)</a>, if necessary.</li>
  467. <li>Register the request handlers for the custom Web pages.</li>
  468. <li><a href="api.html#join">Join</a> prepared AutoConnectAux(s) to AutoConnect.</li>
  469. <li>Invoke <a href="api.html#begin">AutoConnect::begin()</a>.</li>
  470. </ol>
  471. <p>In addition to the above procedure, to completely cut off for binding with the ArduinoJson library, turn off the ArduinoJson use indicator which is declared by the <a href="api.html#defined-macros">AutoConnect definitions</a>. Its declaration is in <strong>AutoConnectDefs.h</strong> file.<sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup></p>
