ESPAsync_WiFiManager Library to use ESPAsyncWebServer instead of (ESP8266)WebServer


ESPAsync_WiFiManager

How To Install Using Arduino Library Manager


Why do we need this ESPAsync_WiFiManager Library

- 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 extendible 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


New in v1.0.11

1. Initial coding to use ESPAsyncWebServer instead of (ESP8266)WebServer.
2. Bump up to v1.0.11 to sync with ESP_WiFiManager v1.0.11.


So, how it works?

In ConfigPortal Mode, it starts an access point called ESP_XXXXXX. Connect to it using the configurable password you can define in the code. For example, your_password (see examples):



After you connected, please, go to http://192.168.4.1, you'll see this `Main` page:




Select `Information` to enter the Info page where the board info will be shown (long page)




or short page (default)




Select Configuration to enter this page where you can select an AP and specify its WiFi Credentials




Enter your credentials, then click Save. The WiFi Credentials will be saved and the board reboots to connect to the selected WiFi AP.

If you're already connected to a listed WiFi AP and don't want to change anything, just select Exit Portal from the Main page to reboot the board and connect to the previously-stored AP. The WiFi Credentials are still intact.


Debug Termimal Output Samples

1. This is terminal debug output when running Async_ConfigOnSwitchFS_MQTT_Ptr on ESP8266 NodeMCU 1.0.. Config Portal was requested to input and save MQTT Credentials. The boards then connected to Adafruit MQTT Server successfully.





2. This is terminal debug output when running Async_ConfigOnDoubleReset on ESP32 ESP32_DEV.. Config Portal was requested by DRD to input and save Credentials. The boards then connected to WiFi using new Static IP successfully.




3. This is terminal debug output when running Async_ConfigOnDoubleReset on ESP8266_NODEMCU.. Config Portal was requested by DRD to input and save Credentials. The boards then connected to WiFi using new Static IP successfully.

Major Releases v1.1.1

1. Add MultiWiFi feature to auto(Re)connect to the best WiFi at runtime
2. Fix bug, typo and minor improvement.
3. Completely enhanced examples to use new MultiWiFi feature.
4. Add setCORSHeader function to allow configurable CORS Header. See Using CORS feature
5. Bump up to v1.1.1 to sync with ESP_WiFiManager v1.1.1.
