<p>The above code can be applied to ESP8266. To apply to ESP32, replace <code>ESP8266WebServer</code> class with <code>WebServer</code> and include <code>WiFi.h</code> and <code>WebServer.h</code> of arduino-esp32 appropriately.</p>

<p>After about 30 seconds, if the ESP8266 cannot connect to nearby Wi-Fi spot, you pull out your smartphone and open <em>Wi-Fi settings</em> from the <em>Settings</em> Apps. You can see the <strong>esp8266ap</strong> <sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup> in the list of <em>"CHOOSE A NETWORK..."</em>. Then tap the esp8266ap and enter password <strong>12345678</strong>, a something screen pops up automatically as shown below.</p>

<p>This is the AutoConnect statistics screen. This screen displays the current status of the established connection, WiFi mode, IP address, free memory size, and etc. Also, the <strong>hamburger icon</strong> is the control menu of AutoConnect seems at the upper right. By tap the hamburger icon, the control menu appears as the below.</p>

<p>After connection established, the current status screen will appear. It is already connected to WLAN with WiFi mode as WIFI_AP_STA and the IP connection status is displayed there including the SSID. Then at this screen, you have two options for the next step.</p>

<p>For one, continues execution of the Sketch while keeping this connection. You can access ESP8266 via browser through the established IP address after cancel to "<strong>Log in</strong>" by upper right on the screen.<br />

Or, "<strong>RESET</strong>" can be selected. The ESP8266 resets and reboots. After that, immediately before the connection will be restored automatically with WIFI_STA mode.</p>
