How To Install Using Arduino Library Manager
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 / Async 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 Synchronous (ESP8266)WebServer.
This ESPAsync_WiFiManager_Lite 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 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
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
Currently supported Boards
