ESP_WiFiManager for ESP32 and ESP8266

Postby khoih-prog » Sat Feb 22, 2020 8:27 pm

You can install directly from Arduino Library Manager

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, 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.

Releases 1.0.9

1. Fix ESP32 STAstaticIP bug.
2. Enable changing from DHCP <-> static IP using Config Portal.
3. Enable NTP configuration from sketch (USE_ESP_WIFIMANAGER_NTP, USE_CLOUDFLARE_NTP). See Issue #21: CloudFlare link in the default portal.
4. Add, enhance examples (fix MDNS for ESP32 examples, add DRD feature).

Releases 1.0.8
1. Fix setSTAStaticIPConfig issue. See Static Station IP doesn't work
2. Add LittleFS support for ESP8266 core 2.7.1+ in examples to replace deprecated SPIFFS.
3. Restructure code.

Releases 1.0.7

1. Use `just-in-time` scanWiFiNetworks() to reduce connection time necessary for battery-operated DeepSleep application. Thanks to CrispinP for identifying, requesting and testing. See Starting WiFIManger is very slow (2000ms)
2. Fix bug relating SPIFFS in examples :
- ConfigOnSwitchFS
- ConfigPortalParamsOnSwitch (now support ArduinoJson 6.0.0+ as well as 5.13.5-)
- AutoConnectWithFSParameters
See Having issue to read the SPIFF file, Thanks to OttoKlaasen to report.
3. Fix README. See Accessing manager after connection
