In this case, AutoConnect allocates an instance of the ESP8266WebServer internally. The logic sequence of the sketch is somewhat different as the above. To register a URL handler function by \nESP8266WebServer::on\n should be performed after \nAutoConnect::begin\n.\n\n\n\n\n\n\n3. No need WiFI.begin(...)\n\u00b6\n\n\nAutoConnect internally performs \nWiFi.begin\n to establish a WiFi connection. There is no need for a general process to establish a connection using \nWiFi.begin\n with a sketch code.\n\n\n4. Alternate ESP8266WebServer::begin()\n\u00b6\n\n\nAutoConnect::begin\n executes \nESP8266WebServer::begin\n internally too and it starts the DNS server to behave as a Captive portal. So it is not needed to call \nESP8266WebServer::begin\n with the sketch.\n\n\n\n\nWhy DNS Server starts\n\n\nAutoConnect traps the detection of the captive portal and achieves a connection with the WLAN interactively by the AutoConnect menu. It responds SoftAP address to all DNS queries temporarily to trap. When the WLAN connection establishes, then stops DNS server.\n\n\n\n\n5. AutoConnect::begin with SSID and Password\n\u00b6\n\n\nSSID and Password can also specify by \nAutoConnect::begin\n. ESP8266 uses provided SSID and Password explicitly. If the connection false with specified SSID with Password then a captive portal is activated. SSID and Password are not present, ESP8266 SDK will attempt to connect using the still effectual SSID and password. Usually, it succeeds.\n\n\n6. Use ESP8266WebServer::on to handle URL\n\u00b6\n\n\nAutoConnect is designed to coexist with the process for handling the web pages by user sketches. The page processing function which will send an HTML to the client invoked by the \"\non::ESP8266WebServer\n\" function is the same as when using ESP8266WebServer natively.\n\n\n7.

Also included in the sample folder, HandlePortal.ino also shows how to use the \nPageBuilder\n library for HTML assemblies.\n\n\nWhat does this example do?\n\u00b6\n\n\nUses the web interface to light the LED connected to the \nNodeMCU\n module D0 port (which could be referred to as \nBUILTIN_LED\n), the following animation is it.\n\n\nAccess to the ESP8266 module connected WiFi from the browser then the page contains the current value of the D0 port would be displayed. The page has the buttons to switch the port value. The LED blinks according to the value of the button that was clicked. This example is a typical sketch of manipulating ESP8266's GPIO via WLAN.\n\n\n\n\nEmbed AutoConnect library into this sketch. There are few places to be changed. And you can use AutoConnect's captive portal function to establish a connection freely to other WiFi spots.\n\n\nEmbed AutoConnect\n\u00b6\n\n\n Pattern A.\n\u00b6\n\n\nBind to ESP8266WebServer, performs handleClient with handleRequest.\n\n\n\n\n\n\nIn what situations should the handleRequest be used.\n\n\nIt is something needs to be done immediately after the handle client. It is better to call only AutoConnect::handleClient whenever possible.\n\n\n\n\n Pattern B.\n\u00b6\n\n\nDeclare only AutoConnect, performs handleClient.\n\n\n\n\nUsed with MQTT as a client application\n\u00b6\n\n\nThe effect of AutoConnect is not only for ESP8266 as the Web server. It has advantages for something WiFi client as well. For example, AutoConnect is also effective for publishing MQTT messages from various measurement points. Even if the SSID is different for each measurement point, it is not necessary to modify the sketch.\n\n\nThis example tries to publish the WiFi signal strength of ESP8266 with MQTT. It uses the \nThingSpeak\n for MQTT broker. ESP8266 publishes the RSSI value to the channel created on ThingSpeak as \nMQTT client\n. This example is well suited to demonstrate the usefulness of AutoConnect, as RSSI values are measured at each access point usually. Just adding a few lines of code makes it unnecessary to upload sketches with the different SSIDs rewrite for each access point.\n\n\n\n\nAdvance procedures\n\u00b6\n\n\n\n\nArduino Client for MQTT - It's the \nPubSubClient\n, install it to Arduino IDE. If you have the latest version already, this step does not need.\n\n\nCreate a channel on ThingSpeak.\n\n\nGet the Channel API Keys from ThingSpeak, put its keys to the sketch.\n\n\n\n\nThe ThingSpeak is the open IoT platform. It is capable of sending data privately to the cloud and analyzing, visualizing its data. If you do not have an account of ThingSpeak, you need that account to proceed further. ThingSpeak has the free plan for the account which uses within the scope of this example.\n1\n You can sign up with the \nThingSpeak sign-up page\n.\n\n\n\n\nWhether you should do sign-up or not.\n\n\nYou are entrusted with the final judgment of account creation for ThingSpeak. Create an account at your own risk.\n\n\n\n\nCreate a channel on ThingSpeak\n\u00b6\n\n\nSign in ThingSpeak. Select \nChannels\n to show the \nMy Channels\n, then click \nNew Channel\n.\n\n\nAt the \nNew Channel\n screen, enter each field as a below. And click \nSave Channel\n at the bottom of the screen to save.\n\n\n\n\nName: \nESP8266 Signal Strength\n\n\nDescription: \nESP8266 RSSI publish\n\n\nField1: \nRSSI\n\n\n\n\n\n\nGet Channel ID and API Keys\n\u00b6\n\n\nThe channel successfully created, you can see the channel status screen as a below. \nChannel ID\n is displayed there.\n2\n\n\n\n\nHere, switch the channel status tab to \nAPI Keys\n. The API key required to publish the message is the \nWrite API Key\n.\n\n\n\n\nThe last key you need is the \nUser API Key\n and can be confirmed it in the user profile. Pull down \nAccount\n from the top menu, select \nMy profile\n. Then you can see the ThingSpeak settings and the \nUser API Key\n is displayed middle of this screen.\n\n\n\n\nThe sketch, Publishes messages\n\u00b6\n\n\nThe complete code of the sketch is \nmqttRSSI.ino\n in the \nAutoConnect repository\n. Replace the following #define in a sketch with \nUser API Key\n, \nWrite API Key\n and \nChannel ID\n. After Keys updated, compile the sketch and upload it.\n\n\n#define MQTT_USER_KEY \"****************\" \n// Replace to User API Key.\n\n\n#define CHANNEL_ID \"******\" \n// Replace to Channel ID.\n\n\n#define CHANNEL_API_KEY_WR \"****************\" \n// Replace to the write API Key.\n\n\n\n\n\nPublish messages\n\u00b6\n\n\nAfter upload and reboot complete, the message publishing will start via the access point now set. The message carries RSSI as the current WiFi signal strength.

The login success response varies iOS, Android and Windows. By analyzing the request URL of different login success inquiries for each OS, the correct behavior can be implemented, but not yet. Please resets ESP8266 from the AutoConnect menu.\n\n\n\n\n\n\n\n\n\n\nThere may be 0xff as an invalid data in the credential saving area. The 0xff area would be reused.\u00a0\n\u21a9",

Max length is 32 bytes. variable variable Password plain text terminated by 0x00. Max length is 64 bytes. variable 6 BSSID variable Contained the next entries. (Continuation SSID+Password+BSSID) variable 1 0x00. End of container. Hint With the ESPShaker , you can access EEPROM interactively from the serial monitor, and of course you can erase saved credentials.",
