< p > Registering the "not found" handler is a different way than ESP8266WebServer/WebServer. The < em > onNotFound< / em > of ESP8266WebServer/WebServer does not work with AutoConnect. AutoConnect overrides < em > ESP8266WebServer::onNotFound< / em > /< em > WebServer::onNotFound< / em > to handle a captive portal. To register "not found" handler, use < a href = "../api/index.html#onnotfound" > < em > AutoConnect::onNotFound< / em > < / a > .< / p >

< p > When the captive portal is started, SoftAP starts and the STA is disconnected. The current SSID setting memorized in ESP8266 will be lost but then the reconnect behavior of ESP32 is somewhat different from this.< br / >
The < a href = "https://github.com/espressif/arduino-esp32/blob/a0f0bd930cfd2d607bf3d3288f46e2d265dd2e11/libraries/WiFi/src/WiFiSTA.h#L46" > WiFiSTAClass::disconnect< / a > function implemented in the arduino-esp32 has extended parameters than the ESP8266's arduino-core. The second parameter of WiFi.disconnect on the arduino-esp32 core that does not exist in the < a href = "https://github.com/esp8266/Arduino/blob/7e1bdb225da8ab337373517e6a86a99432921a86/libraries/ESP8266WiFi/src/ESP8266WiFiSTA.cpp#L296" > ESP8266WiFiSTAClass< / a > has the effect of deleting the currently connected WiFi configuration and its default value is "false". On the ESP32 platform, even if WiFi.disconnect is executed, WiFi.begin() without the parameters in the next turn will try to connect to that AP. That is, automatic reconnection is implemented in arduino-esp32 already. Although this behavior appears seemingly competent, it is rather a disadvantage in scenes where you want to change the access point each time. When explicitly disconnecting WiFi from the Disconnect menu, AutoConnect will erase the AP connection settings saved by arduino-esp32 core. AutoConnect's automatic reconnection is a mechanism independent from the automatic reconnection of the arduino-esp32 core.< br / >
If the < a href = "../api/index.html#autoreconnect" > < strong > autoReconnect< / strong > < / a > option of the < a href = "../api/index.html#autoconnectconfig-api" > < strong > AutoConnectConfig< / strong > < / a > class is enabled, it automatically attempts to reconnect to the disconnected past access point. When the autoReconnect option is specified, AutoConnect will not start SoftAP immediately if the first WiFi.begin fails. It will scan WiFi signal and the same connection information as the detected BSSID is stored in EEPROM as AutoConnect's credentials, explicitly apply it with WiFi.begin and rerun.< / p >

< p > It is also possible to assign static IP Address to ESP8266/ESP32 in STA mode. By default DHCP is enabled and it becomes the IP address assigned by the DHCP server with < em > WiFi.begin< / em > .< / p >
