<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>

<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>
