ESPAsync_WiFiManager_Lite for ESP32 / ESP8266

ESPAsync_WiFiManager_Lite (Light Weight Credentials / WiFiManager for ESP32/ESP8266)

arduino-library-badgeGitHub release


Why do we need this ESPAsync_WiFiManager_Lite library

Features

If you have used one of the full-fledge Async WiFiManagers such as :

  1. Alan Steremberg's ESPAsyncWiFiManager
  2. Khoi Hoang ESPAsync_WiFiManager

and have to write complicated callback functions to save custom parameters in SPIFFS/LittleFS/EEPROM, you’d appreciate the simplicity of this Light-Weight Credentials / WiFiManager.

This is a Light-Weight Credentials / WiFi Connection Manager for ESP32 and ESP8266 boards, designed to use the better and faster asynchronous ESPAsyncWebServer instead of (ESP8266)WebServer.

The ESPAsync_WiFiManager_Lite library permits the easy addition of custom parameters to be configured in Config Portal. The parameters then will be saved automatically, without the complicated callback functions to handle data saving / retrieving.

You can also specify DHCP HostName, static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Config Portal will be auto-adjusted to match the number of dynamic custom parameters. Credentials are saved in LittleFS, SPIFFS or EEPROM.

The web configuration portal, served from the ESP32/ESP8266 WiFi is operating as an access point (AP) with configurable static IP address or use default IP Address of 192.168.4.1

New recent features:

  • MultiWiFi feature for configuring/auto(re)connecting ESP32/ESP8266 WiFi to the available MultiWiFi APs at runtime.
  • Multi/DoubleDetectDetector feature to force Config Portal when multi/double reset is detected within predetermined time, default 10s.
  • Powerful-yet-simple-to-use feature to enable adding dynamic custom parameters from sketch and input using the same Config Portal. Config Portal will be auto-adjusted to match the number of dynamic parameters.
  • Optional default Credentials as well as Dynamic parameters to be optionally autoloaded into Config Portal to use or change instead of manually input.
  • Dynamic custom parameters to be saved automatically in non-volatile memory, such as LittleFS, SPIFFS or EEPROM..
  • Configurable Config Portal Title to be either BoardName or default undistinguishable names.
  • Examples are designed to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
  • Control Config Portal from software or Virtual Switches
  • To permit autoreset after configurable timeout if DRD/MRD or non-persistent forced-CP
  • Use new ESP32 LittleFS features

Thanks to this ESPAsync_WiFiManager_Lite library is based on and sync’ed with ESP_WiFiManager_Lite, all the features currently supported by ESP_WiFiManager_Lite will be available.

Why Async is better

  • Using asynchronous network means that you can handle more than one connection at the same time
  • You are called once the request is ready and parsed
  • When you send the response, you are immediately ready to handle other connections while the server is taking care of sending the response in the background
  • Speed is OMG
  • Easy to use API, HTTP Basic and Digest MD5 Authentication (default), ChunkedResponse
  • Easily extensible to handle any type of content
  • Supports Continue 100
  • Async WebSocket plugin offering different locations without extra servers or ports
  • Async EventSource (Server-Sent Events) plugin to send events to the browser
  • URL Rewrite plugin for conditional and permanent url rewrites
  • ServeStatic plugin that supports cache, Last-Modified, default index and more
  • Simple template processing engine to handle templates

To appreciate the power of the ESPAsyncWebServer and underlying Async libraries, please compare the more efficient Async_ESP32_FSWebServer example example with the complicated twin ESP32_FSWebServer.
