ESP_WiFiManager for ESP32/ESP8266 supporting MultiWiFi/LittleFS and ESP32-S2 now.

[khoih-prog]

https://github.com/khoih-prog/ESP_WiFiManager

You can install directly from Arduino Library Manager

https://www.ardu-badge.com/ESP_WiFiManager

This is an ESP32 / ESP8266 WiFi Connection Manager with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- .

So, how it works?
In Configuration Portal 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):

Code: Select all

// SSID and PW for Config Portal
String ssid = "ESP_" + String(ESP_getChipId(), HEX);
const char* password = "your_password";

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

This is terminal debug output when running ESP32_FSWebServer_DRD on ESP32 ESP32_DEV. Config Portal was requested by DRD to input and save Credentials. The boards then connected to WiFi AP HueNet1 using new Static IP successfully. WiFi AP HueNet1 is then lost, and board autoreconnects itself to backup WiFi AP HueNet2.

Hi,
Thanks for sharing.
I just tested with ConfigOnDRD_FS_MQTT_Ptr example and found out a bug which it won't save the data field of AIO SERVER for MQTT. Thanks.
