=Функция available()&amp;lt;ref&amp;gt;[https://www.arduino.cc/en/Reference/WiFiServerAvailable Arduino.cc - WiFiServerAvailable]&amp;lt;/ref&amp;gt;=&lt;br /&gt;
&lt;br /&gt;
Вылавливает клиента, подключенного к серверу и имеющего данные, доступные для считывания. Соединение сохраняется, даже если клиент исчез из поля зрения. Однако соединение всегда можно закрыть вызовом функции [[Arduino:Библиотеки/WiFi/Класс Client/stop()|client.stop()]]. &lt;br /&gt;
&lt;br /&gt;
Наследует у класса [[Arduino:Справочник языка Arduino/Библиотеки/Stream|Stream]].&lt;br /&gt;
&lt;br /&gt;
==Синтаксис==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;syntaxhighlight lang=&amp;quot;c&amp;quot;&amp;gt;&lt;br /&gt;
server.available()&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Параметры==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;syntaxhighlight lang=&amp;quot;c&amp;quot;&amp;gt;&lt;br /&gt;
Нет.&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Что возвращает==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;syntaxhighlight lang=&amp;quot;c&amp;quot;&amp;gt;&lt;br /&gt;
Объект Client. Если у клиента нет данных, доступных для считывания, то в операторе if (см. пример ниже), возвращенное значение будет рассматриваться как false.&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;
&lt;br /&gt;
