|
|
<p>If you can access the <strong>AutoConnect root path</strong> as <a href="http://ESP8266IPADDRESS/_ac">http://ESP8266IPADDRESS/_ac</a> from browser, probably the Sketch uses <em>ESP8266WebServer::handleClient()</em> without <a href="api.html#handlerequest"><em>AutoConnect::handleRequest()</em></a>.<br />
|
|
For AutoConnect menus to work properly, call <a href="api.html#handlerequest"><em>AutoConnect::handleRequest()</em></a> after <em>ESP8266WebServer::handleClient()</em> invoked, or use <a href="api.html#handleclient"><em>AutoConnect::handleClient()</em></a>. <a href="api.html#handleclient"><em>AutoConnect::handleClient()</em></a> is equivalent <em>ESP8266WebServer::handleClient</em> combined <a href="api.html#handlerequest"><em>AutoConnect::handleRequest()</em></a>.</p>

|
|
<p>Since AutoConnect v1.0.0 for ESP32, the storage location in the flash of established credentials has moved from EEPROM to Preferences. After You update AutoConnect to v1.0.0, past credentials saved by v0.9.12 earlier will <em>not be accessible</em> from the AutoConnect menu - <strong>Open SSIDs</strong>. You need to transfer once the stored credentials from the EEPROM area to the Preferences area.</p>
|
|
<p>You can migrate the past saved credentials using <a href="https://github.com/Hieromon/AutoConnect/tree/master/examples/CreditMigrate"><strong>CreditMigrate.ino</strong></a> which the examples folder contains.</p>

|
|
<p>Captive portal detection could not be trapped. It is necessary to disconnect and reset ESP8266 to clear memorized connection data in ESP8266. Also, It may be displayed on the smartphone if the connection information of esp8266ap is wrong. In that case, delete the connection information of esp8266ap memorized by the smartphone once.</p>

|
<p>If the user sketch includes the header file as <code>EEPROM.h</code>, this compilation error may occur depending on the order of the <code>#include</code> directives. <code>AutoConnectCredentials.h</code> including in succession linked from <code>AutoConnect.h</code> defines <strong>NO_GLOBAL_EEPROM</strong> internally, so if your sketch includes <code>EEPROM.h</code> after <code>AutoConnect.h</code>, the <strong>EEPROM</strong> global variable will be lost.</p>
|
|
<p>If you use EEPROM with your sketch, declare <code>#include <EEPROM.h></code> in front of <code>#include <AutoConnect.h></code>.</p>

|
|
<p>You can avoid a compile error in one of two ways:</p>
|
|
<ol>
|
|
<li>
|
|
<p>Disable an AutoConnectUpdate feature if you don't need.</p>
|
|
<p>You can disable the AutoConnectUpdate feature by commenting out the <a href="https://github.com/Hieromon/AutoConnect/blob/master/src/AutoConnectDefs.h#L34"><strong>AUTOCONNECT_USE_UPDATE</strong></a> macro in the <a href="api.html#defined-macros"><code>AutoConnectDefs.h</code></a> header file.

|
|
<p>A captive portal is disconnected immediately after the connection establishes with the new AP. This is a known problem of ESP32, and it may occur when the following conditions are satisfied at the same time.</p>
|
|
<ul>
|
|
<li>SoftAP channel on ESP32 and the connecting AP channel you specified are different. (The default channel of SoftAP is 1.)</li>
|
|
<li>NVS had erased by erase_flash causes the connection data lost. The NVS partition has been moved. Never connected to the AP in the past.</li>
|
|
<li>There are receivable multiple WiFi signals which are the same SSID with different channels using the WiFi repeater etc. (This condition is loose, it may occur even if there is no WiFi repeater.)</li>
|
|
<li>Or the using channel of the AP which established a connection is congested with the radio signal on the same band. (If the channel crowd, connections to known APs may also fail.)</li>
|
|
</ul>
|
|
<div class="admonition info">
|
|
<p class="admonition-title">Other possibilities</p>
|
|
<p>The above conditions are not absolute. It results from my investigation, and other conditions may exist.</p>
|
|
</div>
|
|
<p>To avoid this problem, try <a href="#1-change-wifi-channel">changing the channel</a>.</p>
|
|
<p>ESP32 hardware equips only one RF circuitry for WiFi signal. At the AP_STA mode, ESP32 as an AP attempts connect to another AP on another channel while keeping the connection with the station then the channel switching will occur causes the station may be disconnected. But it may not be just a matter of channel switching causes ESP8266 has the same constraints too. It may be a problem with AutoConnect or the arduino core or SDK issue. This problem will persist until a specific solution.</p>

|
|
<p>By default, AutoConnect saves the credentials of the established connection into EEPROM. The credential area of EEPROM used by AutoConnect will conflict with data owned by the user sketch if without measures taken. It will destroy the user sketch data and the data stored in EEPROM by AutoConnect with each other.<br />
|
|
You have the following two options to avoid this conflict:</p>
|
|
<ul>
|
|
<li>
|
|
<p>Move the credential saving area of EEPROM.<br />
|
|
You can protect your data from corruption by notifying AutoConnect where to save credentials. Notification of the save location for the credentials uses <a href="apiconfig.html#boundaryoffset">AutoConnectConfig::boundaryOffset</a> option. Refer to the chapter on <a href="advancedusage.html#move-the-saving-area-of-eeprom-for-the-credentials">Advanced usage</a> for details.</p>
|
|
</li>
|
|
<li>
|
|
<p>Suppresses the automatic save operation of credentials by AutoConnect.<br />
|
|
You can completely stop saving the credentials by AutoConnect. However, if you select this option, you lose the past credentials which were able to connect to the AP. Therefore, the effect of the <a href="advancedusage.html#automatic-reconnect">automatic reconnection feature</a> will be lost.<br />
|
|
If you want to stop the automatic saving of the credentials, uses <a href="apiconfig.html#autosave">AutoConnectConfig::autoSave</a> option specifying <strong>AC_SAVECREDENTIAL_NEVER</strong>. Refer to the chapter on <a href="advancedusage.html#autosave-credential">Advanced usage</a> for details.</p>
|
|
</li>
|
|
</ul>

|
|
<p>Maybe it is successfully connected at the <a href="lsbegin.html#autoconnectbegin-logic-sequence"><strong>first WiFi.begin</strong></a>. ESP8266 remembers the last SSID successfully connected and will use at the next. It means SoftAP will only start up when the first <em>WiFi.begin()</em> fails.</p>
|
|
<p>The saved SSID would be cleared by <em>WiFi.disconnect()</em> with WIFI_STA mode. If you do not want automatic reconnection, you can erase the memorized SSID with the following simple sketch.</p>

<p>If ESP8266 hang up after reset by AutoConnect menu, perhaps manual reset is not yet. Especially if it is not manual reset yet after uploading the Sketch, the boot mode will stay 'Uart Download'. There is some discussion about this on the Github's ESP8266 core: <a href="https://github.com/esp8266/Arduino/issues/1017">https://github.com/esp8266/Arduino/issues/1017</a> <sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup></p>

|
|
<p>If you don't use ArduinoJson at all, you can detach it from the library. By detaching ArduinoJson, the binary size after compilation can be reduced. You can implement custom Web pages with your sketches without using ArduinoJson. Its method is described in <a href="wojson.html">Custom Web pages w/o JSON</a>.<br />
|
|
To completely remove ArduinoJson at compile-time from the binary, you need to define a special <code>#define</code> directive for it. And if you define the directive, you will not be able to use the <a href="otaserver.html#updates-with-the-update-server">OTA update with the update server</a> feature as well as AutoConnectAux described by JSON.</p>

<p>Make some sketches for erasing the EEPROM area, or some erasing utility is needed. You can prepare the Sketch to erase the saved credential with <em>AutoConnectCredential</em>. The <em>AutoConnectCrendential</em> class provides the access method to the saved credential in EEPROM and library source file is including it. Refer to '<a href="credit.html#saved-credential-in-eeprom">Saved credential access</a>' on section <a href="credit.html">Appendix</a> for details.</p>

<p>Because AutoConnect does not send a login success response to the captive portal requests from the smartphone. 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.</p>

<p>If the Sketch is correct, a JSON syntax error may have occurred. In this case, activate the <a href="faq.html#3-turn-on-the-debug-log-options">AC_DEBUG</a> and rerun. If you take the message of JSON syntax error, the <a href="https://arduinojson.org/v5/assistant/">Json Assistant</a> helps syntax checking.

<p>A structure of AutoConnect saved credentials has changed two times throughout enhancement with v1.0.3 and v1.1.0. In particular, due to enhancements in v1.1.0, AutoConnectCredential data structure has lost the backward compatibility with previous versions. You must erase the flash of the ESP module using the esptool completely to save the credentials correctly with v1.1.0.

<p>It may be two possibilities as follows:</p>
|
|
<ol>
|
|
<li>Packet loss during transmission due to a too weak WiFi signal.</li>
|
|
<li>Heap is insufficient memory. AutoConnect entrusts HTML generation to PageBuilder that makes heavy use the String::concatenate function and causes memory fragmentation. This is a structural problem with PageBuilder, but it is difficult to solve immediately.</li>
|
|
</ol>
|
|
<p>If this issue produces with your sketch, Reloading the page may recover.<br />
|
|
Also, you can check the memory running out status by rebuilding the Sketch with <a href="faq.html#fn:2">PageBuilder's debug log option</a> turned on.</p>
|
|
<p>If the heap memory is insufficient, the following message is displayed on the serial console.</p>

|

<p>Is there the AutoConnectElements element named <strong>SUBMIT</strong> in the custom Web page? (case sensitive ignored) AutoConnect does not rely on the <code>input type=submit</code> element for the form submission and uses <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/submit">HTML form element submit</a> function instead. So, the submit function will fail if there is an element named 'submit' in the form. You can not use <strong>SUBMIT</strong> as the element name of AutoConnectElements in a custom Web page that declares the AutoConnectSubmit element.</p>

<p>Both ESP8266 and ESP32 can only work on one channel at any given moment. This will cause your station to lose connectivity on the channel hosting the captive portal.

In such a case, please try to configure the <a href="apiconfig.html#channel">channel</a> with <a href="apiconfig.html#autoconnectconfig">AutoConnectConfig</a> to match the access point.</p>

<p>You can select the <a href="http://lwip.wikia.com/wiki/LwIP_Wiki">lwIP</a> variant to contribute for the stable behavior. The <strong>lwIP v2 Lower memory</strong> option of Arduino IDE for core version 2.4.2 is based on the lwIP-v2. On the other hand, the core version 2.5.0 upstream is based on the lwIP-2.1.2 stable release.</p>
|
|
<p>You can select the option from Arduino IDE as <strong>Tool</strong> menu, if you are using ESP8266 core 2.5.0. It can be select <code>lwIP v2 Lower Memory</code> option. (not <code>lwIP v2 Lower Memory (no features)</code>) It is expected to improve response performance and stability.</p>
