How To Install Using 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- .


This library is based on, modified, bug-fixed and improved from:

1. Tzapu WiFiManager
2. Ken Taylor WiFiManager

to add support to ESP32 besides ESP8266.


## 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]


// 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.

This is a very nice library!

Is there a way to enter a static ip address in the portal? I want users to choose between dhcp or static in the portal.

[khoih-prog]

Thanks for your interests in the library.

Is there a way to enter a static ip address in the portal? I want users to choose between dhcp or static in the portal.

It's currently supported and suggested that you go through all the Examples to familiarize yourself and take advantage of all the provided features .

Please have a look at 

How It Works

especially these parts:

4. Using STA-mode DHCP, but permit to change to static IP and display in Config Portal
5. Using STA-mode StaticIP, and be able to change to DHCP IP and display in Config Portal
6. Using STA-mode StaticIP and configurable DNS, and be able to change to DHCP IP and display in Config Portal
7. Using STA-mode StaticIP and auto DNS, and be able to change to DHCP IP and display in Config Portal

[rwanrooy]

Thank you for your quick reply.

I looked at the examples and found the code. I can enter a fixed ip in the sketch and show it in the portal but I am not able to set an ip in the portal itself. What I want is that the esp boots using dhcp as default and that it is possible to enter a fixed ip in the portal, not in the sketch. Am I missing something in the examples?

[khoih-prog]

I suggested you to use this ConfigOnDoubleReset 

and follow:

4. Using STA-mode DHCP, but permit to change to static IP and display in Config Portal

You have to spend time playing with the examples to get the experience. No easy way. I'm sorry I can't help any further with the basic usage.

[rwanrooy]

Thanks for your answer. I configured the sketch as you said and I am able to change the ip address in the portal. I notice that the ip address is changed after I save the settings. I am able to ping the configured ip so that works perfect. After a reboot of the esp the configured address is lost. Is there a way to store the configured ip in spiffs?

[khoih-prog]

You're very welcome. I'm now happy that you independently found your way and met the current so-called bug of one example, mentioned in the following issue

ESP32 static IP not saved after restarting the device

This can be fixed easily by writing the Static IP settings, got from CP, into EEPROM/SPIFFS/LittleFS, and retrieving / using them after rebooting.

The steps to write to/read from SPIFFS/LittleFS are described in details here

HOWTO Add Dynamic Parameters

If urgently needed and possible, you can rewrite the example. Then make a Pull-Request (PR) and contribute back to the Community.

[khoih-prog]

Releases v1.3.0

1. Add LittleFS support to ESP32-related examples to use LittleFS_esp32 Library
2. Add Version String

Releases v1.2.0

1. Restore cpp code besides Impl.h code to use in case of multiple definition linker error.
2. Fix bug /close does not close the config portal

[rwanrooy]

I saw the sketches were updated with the static ip configuration in the portal. I'm using the https://github.com/khoih-prog/ESP_WiFiManager/tree/master/examples/ConfigOnSwitchFS_MQTT_Ptr sketch now which saves the static ip to FS. I am only able to do this the first time. When I press the button, the portal comes up and when I configure the static ip, it does not remember the new ip.

I then tried the https://github.com/khoih-prog/ESP_WiFiManager/tree/master/examples/ConfigPortalParamsOnSwitch so without MQTT and that does save the ip after the initial config is done and reconfigured with the button.

I have searched all day but didn't find the code which saves the ip after the initial setup. Can you give me a hint or correct the MQTT sketch so that I can alter the static ip after the initial config is done?

[khoih-prog]

You have to use the latest releases (v1.4.1+) where the bug has been fixed

Releases v1.4.2

1. Fix examples' bug not using saved WiFi Credentials after losing all WiFi connections.
2. Fix compiler warnings.

Major Releases v1.4.1

1. Fix staticIP not saved in examples. Check ESP32 static IP not saved after restarting the device
2. Add structures and functions to handle AP and STA IPs.
3. Add complex examples
4. Add simple minimal examples
5. Fix bug.
6. Fix compiler warnings.
7. Modify Version String
8. Add Table of Contents

[rwanrooy]

I am using version 1.4.2 and the ip is saved at the initial setup. when you do it again it doesn't save the new ip address with the https://github.com/khoih-prog/ESP_WiFiManager/tree/master/examples/ConfigOnSwitchFS_MQTT_Ptr example. with the https://github.com/khoih-prog/ESP_WiFiManager/tree/master/examples/ConfigPortalParamsOnSwitch it is working ok. so there has to be a difference but I can't find it

[khoih-prog]

I've just spent some time to re-test and am sure the example is working OK as intended. It's possibly you're using the different, not-yet-fixed or modified version of it.

If you experience something different, it's a good opportunity for you to read the code / examples to get deeper understanding of the library.

I'm sorry I won't spend more time on the same issue until convincing proof of bug is provided.

Hereafter are the debug terminal outputs to show you it's currently working OK

[rwanrooy]

Thanks for your answer and testing. I did some testing too. When a static ip of dhcp address is already configured/used it is nessecary to enter the wifi credentials when setting a static ip address. When you don't enter the wifi credentials the static ip is not stored.

So I have another question. There are two SSID credential forms displayed on the portal. When I set

Code: [Select]

#define NUM_WIFI_CREDENTIALS      2
to

Code: [Select]

#define NUM_WIFI_CREDENTIALS      1
the config portal does not change to display only one ssid configuration form. Is it possible to make this dynamic or just remove SSID1 from the portal? Most people don't use two ssid's and reconfigure the esp when they make changes to their wifi network.

I also changed the following in the example

Code: [Select]

IPAddress stationIP   = IPAddress(192, 168, 2, 232);
to

Code: [Select]

IPAddress stationIP   = IPAddress(0, 0, 0, 0);

This changes the behaviour when the 0.0.0.0 address is not altered, it stays at dhcp. When changed it is set to static. This makes it easier for people to see if the esp is set to dhcp or static.

Your help would be really appreciated.
