Please have a look atHOWTO FixMultiple Definitions Linker Error
From v1.9.0, you just use
#include <ESP_WiFiManager.h> //https://github.com/khoih-prog/ESP_WiFiManagerinstead of both

Please have a look atHOWTO FixMultiple Definitions Linker Error
From v1.8.0, you must use
#include <ESP_WiFiManager.h> //https://github.com/khoih-prog/ESP_WiFiManager// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error#include <ESP_WiFiManager-Impl.h> //https://github.com/khoih-prog/ESP_WiFiManagerinstead of only
#include <ESP_WiFiManager.h> //https://github.com/khoih-prog/ESP_WiFiManagerThisESP_WiFiManager has just been modified to create the newESPAsync_WiFiManager Library in order to use the better and more efficientESPAsyncWebServer Library, instead of the (ESP8266)WebServer library.
The newESPAsync_WiFiManager library is based on and sync'ed withESP_WiFiManager. Therefore, all the features currently supported by thisESP_WiFiManager will be available to the new library. The code change is to port to the new library is also very negligible,mostly just changing the Class name from ESP_WiFiManager to ESPAsync_WiFiManager.
Why do we need the new AsyncESPAsync_WiFiManager library
- Using asynchronous network means that you can handlemore than one connection at the same time
- You are called once the request is ready and parsed
- When you send the response, you areimmediately 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 handleany 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
To appreciate the power of theESPAsyncWebServer and underlying Async libraries, please compare the more efficientAsync_ESP32_FSWebServer example example code against the code of its complicated twinESP32_FSWebServer.
Thanks tocancodr for requesting an enhancement inIssue #29: Is it possible to use AsyncWebServer.h instead of WebServer.h?, leading to the newESPAsync_WiFiManager Library.
Why do we need thisESP_WiFiManager library
This is a WiFiManager Library for configuring/auto(re)connectingESP8266/ESP32 modules to the best or available MultiWiFi APs at runtime. Configuration data to be saved in either LittleFS, SPIFFS or EEPROM. Default Credentials as well as Dynamic custom parameters can be added and modified easily. DoubleResetDetector is used to force Config Portal opening even if the Credentials are still valid.
This library is designed to help you to eliminatehardcoding your Wifi credentials for ESP8266 and ESP32, and updating/reflashing every time you need to change them.
With versionv1.3.0 or later, you can use:
LittleFS for ESP32
With versionv1.1.0 or later, you can configure:
Multiple WiFi Credentials (SSID, Password) and system will autoconnect to the best and available WiFi SSID.
ThisESP_WiFiManager library currently supports these following boards:
- ESP8266 and ESP32-based boards using EEPROM, SPIFFS or LittleFS.
- ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.) using EEPROM, SPIFFS or LittleFS.
- ESP32-C3 (ARDUINO_ESP32C3_DEV) using EEPROM, SPIFFS or LittleFS.
- ESP32-S3 (ESP32S3_DEV, ESP32_S3_BOX, UM TINYS3, UM PROS3, UM FEATHERS3, etc.) using EEPROM, SPIFFS or LittleFS.
This library is based on, modified, bug-fixed and improved from:
to add support toESP32 besidesESP8266.
This is anESP32 / ESP8266 WiFi Connection manager with fallback web ConfigPortal.It's using a web ConfigPortal, served from theESP32 / ESP8266, and operating as an access point.

- InstallLatest ESP_WiFiManager library by usingLibrary Manager. Search forESP_WiFiManager inPlatform.io Author's Libraries
- Use includedplatformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples atProject Configuration File
From esp32 core v1.0.6+,LittleFS_esp32 v1.0.6 has been included and this step is not necessary anymore.
In Platform IO, to fix the error when usingLittleFS_esp32 v1.0 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line
from
//#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */to
#define CONFIG_LITTLEFS_FOR_IDF_3_2 /* For old IDF - like in release 1.0.4 */It's advisable to use the latestLittleFS_esp32 v1.0.5+ to avoid the issue.
Thanks toRoshan to report the issue inError esp_littlefs.c 'utime_p'
The current library implementation, usingxyz-Impl.h instead of standardxyz.cpp, possibly creates certainMultiple Definitions Linker error in certain use cases.
You can use
#include <ESP_WiFiManager.hpp> //https://github.com/khoih-prog/ESP_WiFiManagerin many files. But be sure to use the following#include <ESP_WiFiManager.h>in just 1.h,.cpp or.ino file, which mustnot be included in any other file, to avoidMultiple Definitions Linker Error
// To be included only in main(), .ino with setup() to avoid `Multiple Definitions` Linker Error#include <ESP_WiFiManager.h> //https://github.com/khoih-prog/ESP_WiFiManagerCheckConfigOnDoubleReset_Multi for an example how and where to do so.
Have a look at the discussion inDifferent behaviour using the src_cpp or src_h lib #80
Please have a look atESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.
- ADC1 controls ADC function for pinsGPIO32-GPIO39
- ADC2 controls ADC function for pinsGPIO0, 2, 4, 12-15, 25-27
Look in fileadc_common.c
In ADC2, there're two locks used for different cases:
lock shared with app and Wi-Fi:ESP32:When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed.ESP32S2:The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.
lock shared between tasks:when several tasks sharing the ADC2, we want to guaranteeall the requests will be handled.Since conversions are short (about 31us), app returns the lock very soon,we use a spinlock to stand there waiting to do conversions one by one.
adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.
- In order to use ADC2 for other functions, we have toacquire complicated firmware locks and very difficult to do
- So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
- Use ADC1, and pins GPIO32-GPIO39
- If somehow it's a must to use those pins serviced by ADC2 (GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use thefix mentioned at the end ofESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).
- TheConfigOnSwitch example shows how it works and should be used as the basis for a sketch that uses this library.
- The concept of ConfigOnSwitch is that a new
ESP32 / ESP8266will start a WiFi ConfigPortal when powered up and save the configuration data in non volatile memory. Thereafter, the ConfigPortal will only be started again if a button is pushed on theESP32 / ESP8266module. - Using any WiFi enabled device with a browser (computer, phone, tablet) connect to the newly created Access Point (AP) using configurable SSID and Password (specified in sketch)
// SSID and PW for Config PortalString ssid ="ESP_" + String(ESP_getChipId(), HEX);constchar* password ="your_password";
then connect WebBrowser to configurable ConfigPortal IP address, default is 192.168.4.1
- Choose one of the access points scanned, enter password, clickSave.
- ESP will restart, then try to connect to the WiFi netwotk using STA-only mode,without running the ConfigPortal WebServer and WiFi AP. SeeAccessing manager after connection.

_timezoneNameto TZ, use the function getTZ() as follows:
const char * TZ_Result = ESP_wifiManager.getTZ(_timezoneName);The conversion depends on the stored TZs, which is using some memory, and can cause issue for ESP8266 in certain cases. Therefore, enable just the region you're interested.

add
ESP_WiFiManagerESP_wifiManager("Personalized-HostName");
then later call
ESP_wifiManager.startConfigPortal()
While in AP mode, connect to it using itsSSID (ESP_XXXXXX) /Password ("your_password"), then open a browser to the AP IP, default192.168.4.1, configure wifi then save. The WiFi connection information will be saved in non volatile memory. It will then reboot and autoconnect.
You can also change the AP IP by:
//set custom ip for portal//ESP_wifiManager.setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));ESP_wifiManager.setAPStaticIPConfig(WM_AP_IPconfig);
and use fixed / dynamic / random AP channel by:
// From v1.0.10 only// Set config portal channel, default = 1. Use 0 => random channel from 1-13ESP_wifiManager.setConfigPortalChannel(0);//////
Once WiFi network information is saved in theESP32 / ESP8266, it will try to autoconnect to WiFi every time it is started, without requiring any function calls in the sketch.
These illustrating steps is based on the exampleConfigOnSwitchFS
The application will:
- use DHT sensor (either DHT11 or DHT22) and
- need to connect to ThingSpeak with unique user's API Key.
The DHT sensor is connected to the ESP boards using SDA/SCL pins which also need to be configurable.
So this is the list of variables to be dynamically configured using CP
1. `thingspeakApiKey`, type `char array`, max length 17 chars, and just arbitrarily selected default value to be "" or "ThingSpeak-APIKey"2. `sensorDht22`, type `bool`, default to be `true` (DHT22)3. `pinSda`, type `int`, default to be `PIN_D2`4. `pinScl`, type `int`, default to be `PIN_D1`The Label can be any arbitrary string that help you identify the variable, but must be unique in your application
The initial code will be
#define API_KEY_LEN 17// Default configuration valueschar thingspeakApiKey[API_KEY_LEN] = "";bool sensorDht22 = true;int pinSda = PIN_D2; // Pin D2 mapped to pin GPIO4 of ESP8266int pinScl = PIN_D1; // Pin D1 mapped to pin GPIO5 of ESP8266// Any unique string helping you identify the vars#define ThingSpeakAPI_Label "thingspeakApiKey"#define SensorDht22_Label "SensorDHT22"#define PinSDA_Label "PinSda"#define PinSCL_Label "PinScl"The exampleConfigOnSwitchFS will open the CP whenever a SW press is detected in loop(). So the code to adddynamic variables will be there, just after the CPESP_WiFiManager class initialization to createESP_wifiManager object.
void loop(){ // is configuration portal requested? if ((digitalRead(TRIGGER_PIN) == LOW) || (digitalRead(TRIGGER_PIN2) == LOW)) { Serial.println("\nConfiguration portal requested."); digitalWrite(PIN_LED, LED_ON); // turn the LED on by making the voltage LOW to tell us we are in configuration mode. //Local intialization. Once its business is done, there is no need to keep it around ESP_WiFiManager ESP_wifiManager("ConfigOnSwitchFS"); //Check if there is stored WiFi router/password credentials. //If not found, device will remain in configuration mode until switched off via webserver. Serial.print("Opening configuration portal. "); ... // The addition of dynamic vars will be somewhere here }TheESP_WMParameter class constructor will be used to initialize each newly-added parameter object.
2.1 Use the following simple constructor for simple variables such asthingspeakApiKey,pinSda andpinScl :
ESP_WMParameter(const char *id, const char *placeholder, const char *defaultValue, int length);The command to use will be
ESP_WMParameter p_thingspeakApiKey(ThingSpeakAPI_Label, "Thingspeak API Key", thingspeakApiKey, API_KEY_LEN);where
- p_thingspeakApiKey : ESP_WMParameter class object reference that stores the new Custom Parameter- id => ThingSpeakAPI_Label : var ref to Json associative name and HTML element ID for the new Custom Paramerter you just defined in step 1- placeholder => "Thingspeak API Key" : HTML input placeholder and/or label element text the user sees in the configuration interface for this Custom Parameter- defaultValue => thingspeakApiKey : variable for storing the value of your Custom Parameter in the file system or default value when no data is entered- length => API_KEY_LEN : max allowed length you want for this Custom Parameter to haveForpinSda andpinScl, the command will be similar
// I2C SCL and SDA parameters are integers so we need to convert them to char array but// no other special considerationschar convertedValue[3];sprintf(convertedValue, "%d", pinSda);ESP_WMParameter p_pinSda(PinSDA_Label, "I2C SDA pin", convertedValue, 3);sprintf(convertedValue, "%d", pinScl);ESP_WMParameter p_pinScl(PinSCL_Label, "I2C SCL pin", convertedValue, 3);where
- p_pinSda / p_pinScl : ESP_WMParameter class object reference that stores the new Custom Parameter- id => PinSDA_Label/PinSCL_Label : var ref to Json associative name and HTML element ID for the new Custom Paramerter you just defined in step 1- placeholder => "I2C SDA pin"/"I2C SCL pin" : HTML input placeholder and/or label element text the user sees in the configuration interface for this Custom Parameter- defaultValue => convertedValue : variable for storing the value of your Custom Parameter in the file system or default value when no data is entered- length => 3 : max allowed length you want for this Custom Parameter to haveESP_WMParameter(const char *id, const char *placeholder, const char *defaultValue, int length, const char *custom, int labelPlacement);The command to use will be
ESP_WMParameter p_sensorDht22(SensorDht22_Label, "DHT-22 Sensor", "T", 2, customhtml, WFM_LABEL_AFTER);where
- p_sensorDht22 : ESP_WMParameter class object reference that stores the new Custom Parameter- id => SensorDht22_Label : var ref to Json associative name and HTML element ID for the new Custom Paramerter you just defined in step 1- placeholder => "DHT-22 Sensor" : HTML input placeholder and/or label element text the user sees in the configuration interface for this Custom Parameter- defaultValue => "T" : variable for storing the value of your Custom Parameter in the file system or default value when no data is entered ("T" means `true`)- length => 2 : max allowed length you want for this Custom Parameter to have- custom => customhtml : custom HTML code to add element type, e.g. `checkbox`, and `checked` when `sensorDht22 == true`- labelPlacement => WFM_LABEL_AFTER : to place label afterand customhtml Code is:
char customhtml[24] = "type=\"checkbox\"";if (sensorDht22){ strcat(customhtml, " checked");}Adding thoseESP_WMParameter objects created in Step 2 using the functionaddParameter() of objectESP_wifiManager
//adds a custom parameterbool addParameter(ESP_WMParameter *p);Add parameter objects, previously created in Step 2, such as :p_thingspeakApiKey,p_sensorDht22,p_pinSda andp_pinScl
//add all parameters hereESP_wifiManager.addParameter(&p_thingspeakApiKey);ESP_wifiManager.addParameter(&p_sensorDht22);ESP_wifiManager.addParameter(&p_pinSda);ESP_wifiManager.addParameter(&p_pinScl);When the CP exits, we have to store the parameters' values that users input via CP to use later.
For ESP32, that can beEEPROM orSPIFFS. While on ESP8266,LittleFS can be used besidesEEPROM ordeprecated SPIFFS.
We can write directly to awell-defined structure of our choice, but the current example is usingJSON to be portable butmuch more complicated and not advised for new users.
After users selectSave, the CPESP_wifiManager object will save the user input data into relatedESP_WMParameter objects.
We can now retrieve the data, usinggetValue() function, for eachESP_WMParameter object. Then we can utilize the data for our purpose, such asthingspeakApiKey to log in,sensorDht22 type to know how to handle the sensor,pinSda andpinSda to know which pins to use to communicate with the DHT sensor.
The code is as follows:
// Getting posted form values and overriding local variables parameters// Config file is written regardless the connection statestrcpy(thingspeakApiKey, p_thingspeakApiKey.getValue());sensorDht22 = (strncmp(p_sensorDht22.getValue(), "T", 1) == 0);pinSda = atoi(p_pinSda.getValue());pinScl = atoi(p_pinScl.getValue());We can also save to FS file to use later in next boot.
// Writing JSON config file to flash for next bootwriteConfigFile();First, you have to familiarize yourself withArduinoJson library, its functions, the disruptive differences betweenArduinoJson version 5.x.x- andv6.0.0+. The best documentation can be found atThe best JSON library for embedded C++.
This documentation will discuss only ArduinoJson v6.x.x+ (ARDUINOJSON_VERSION_MAJOR >= 6)
Then have a look at the code snippet ofwriteConfigFile() function and the following step-by-step explanations.
bool writeConfigFile(){ Serial.println("Saving config file");#if (ARDUINOJSON_VERSION_MAJOR >= 6) DynamicJsonDocument json(1024);#else DynamicJsonBuffer jsonBuffer; JsonObject& json = jsonBuffer.createObject();#endif // JSONify local configuration parameters json[ThingSpeakAPI_Label] = thingspeakApiKey; json[SensorDht22_Label] = sensorDht22; json[PinSDA_Label] = pinSda; json[PinSCL_Label] = pinScl; // Open file for writing File f = FileFS.open(CONFIG_FILE, "w"); if (!f) { Serial.println("Failed to open config file for writing"); return false; }#if (ARDUINOJSON_VERSION_MAJOR >= 6) serializeJsonPretty(json, Serial); // Write data to file and close it serializeJson(json, f);#else json.prettyPrintTo(Serial); // Write data to file and close it json.printTo(f);#endif f.close(); Serial.println("\nConfig file was successfully saved"); return true;}We'll create an object with size 1024 bytes, enough to hold our data:
DynamicJsonDocument json(1024);ThenJSONify all local parameters we've just received from CP and wish to store into FS by using the function prototype:
json[Unique_Label] = Value_For_Unique_Label;as follows:
// JSONify local configuration parametersjson[ThingSpeakAPI_Label] = thingspeakApiKey;json[SensorDht22_Label] = sensorDht22;json[PinSDA_Label] = pinSda;json[PinSCL_Label] = pinScl;This is theCONFIG_FILE file name we already declared at the beginning of the sketch (for ESP32):
#include <SPIFFS.h>FS* filesystem = &SPIFFS;#define FileFS SPIFFS const char* CONFIG_FILE = "/ConfigSW.json";Now just open the file for writing, and abort if open-for-writing error:
// Open file for writingFile f = FileFS.open(CONFIG_FILE, "w");if (!f){ Serial.println("Failed to open config file for writing"); return false;}As simple as this single command to write the wholejson object we declared then filled with data in steps 5.1 and 5.2
// Write data to file and close itserializeJson(json, f);Soooo simple !!! Now everybody can do it.
f.close();ButHOWTO use the saved data in the next startup ???? That's in next step 6.
Now, you have familiarized yourself with ArduinoJson library, its functions. We'll discuss HOWTO read data from the CONFIG_FILE in Jsonified format, then HOWTO parse the to use.
The documentation will discuss only ArduinoJson v6.x.x+ (ARDUINOJSON_VERSION_MAJOR >= 6)
First, have a look at the code snippet ofreadConfigFile() function.
bool readConfigFile(){ // this opens the config file in read-mode File f = FileFS.open(CONFIG_FILE, "r"); if (!f) { Serial.println("Configuration file not found"); return false; } else { // we could open the file size_t size = f.size(); // Allocate a buffer to store contents of the file. std::unique_ptr<char[]> buf(new char[size + 1]); // Read and store file contents in buf f.readBytes(buf.get(), size); // Closing file f.close(); // Using dynamic JSON buffer which is not the recommended memory model, but anyway // See https://github.com/bblanchon/ArduinoJson/wiki/Memory%20model#if (ARDUINOJSON_VERSION_MAJOR >= 6) DynamicJsonDocument json(1024); auto deserializeError = deserializeJson(json, buf.get()); if ( deserializeError ) { Serial.println("JSON parseObject() failed"); return false; } serializeJson(json, Serial);#else DynamicJsonBuffer jsonBuffer; // Parse JSON string JsonObject& json = jsonBuffer.parseObject(buf.get()); // Test if parsing succeeds. if (!json.success()) { Serial.println("JSON parseObject() failed"); return false; } json.printTo(Serial);#endif // Parse all config file parameters, override // local config variables with parsed values if (json.containsKey(ThingSpeakAPI_Label)) { strcpy(thingspeakApiKey, json[ThingSpeakAPI_Label]); } if (json.containsKey(SensorDht22_Label)) { sensorDht22 = json[SensorDht22_Label]; } if (json.containsKey(PinSDA_Label)) { pinSda = json[PinSDA_Label]; } if (json.containsKey(PinSCL_Label)) { pinScl = json[PinSCL_Label]; } } Serial.println("\nConfig file was successfully parsed"); return true;}and the following step-by-step explanations.
As simple as this
// this opens the config file in read-modeFile f = FileFS.open(CONFIG_FILE, "r");We'll inform and abort if the CONFIG_FILE can't be opened (file not found, can't be opened, etc.)
if (!f){ Serial.println("Configuration file not found"); return false;}Now we have to determine the file size to create a buffer large enough to store the to-be-read data
// we could open the filesize_t size = f.size();// Allocate a buffer to store contents of the file.std::unique_ptr<char[]> buf(new char[size + 1]);Remember always add 1 to the buffer length to store the terminating0.
Then just read the file into the buffer, and close the file to be safe
// Read and store file contents in buff.readBytes(buf.get(), size);// Closing filef.close();We again use the sameDynamicJsonDocument json object to store the data we've just read fronCONFIG_FILE.
Why the same complicatedDynamicJsonDocument json object ?? Because in steps 5, we did storeJsonified data using the sameDynamicJsonDocument json object. It's much easier we now use it again to facilitate the parsing ofJsonified data back to the data we can use easily.
We first create the object with enough size
DynamicJsonDocument json(1024);then populate it with data from buffer we read from CONFIG_FILE in step 6.2, pre-parse and check for error. All is done just by one commanddeserializeJson()
auto deserializeError = deserializeJson(json, buf.get());Abort if there is any data error in the process of writing, storing, reading back. If OK, just nicely print out to the Debug Terminal
if ( deserializeError ){ Serial.println("JSON parseObject() failed"); return false;}serializeJson(json, Serial);6.4 Parse the Jsonified data from the DynamicJsonDocument json object to store into corresponding parameters
This is as simple as in the step 5.2, but in reverse direction.
To be sure there is good corresponding data, not garbage, for each variable, we have to performsanity checks byverifying theDynamicJsonDocument json object still contains the correct keys we passed to it when we wrote into CONFIG_FILE.
For example:
if (json.containsKey(ThingSpeakAPI_Label))Then proceed to get every parameter we know we stored there from last CPSave.
// Parse all config file parameters, override// local config variables with parsed valuesif (json.containsKey(ThingSpeakAPI_Label)){ strcpy(thingspeakApiKey, json[ThingSpeakAPI_Label]);}if (json.containsKey(SensorDht22_Label)){ sensorDht22 = json[SensorDht22_Label];}if (json.containsKey(PinSDA_Label)){ pinSda = json[PinSDA_Label];}if (json.containsKey(PinSCL_Label)){ pinScl = json[PinSCL_Label];}Just use those parameters for whatever purpose you designed them for in step 1:
The application will use DHT sensor (either DHT11 or DHT22) and need to connect to ThingSpeak with unique user's API Key. The DHT sensor is connected to the ESP boards using SDA/SCL pins which also need to be configurable.InConfigPortal Mode, it starts an access point calledESP_XXXXXX. Connect to it using theconfigurable password you can define in the code. For example,your_password (see examples):
// SSID and PW for Config PortalString ssid ="ESP_" + String(ESP_getChipId(), HEX);constchar* password ="your_password";
After you connected, please, go tohttp://192.168.4.1, you'll see thisMain page:
SelectInformation to enter the Info page where the board info will be shown (long page)
or short page (default)
SelectConfiguration to enter this page where you can select an AP and specify its WiFi Credentials
Enter your credentials, then clickSave. 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 selectExit Portal from theMain page to reboot the board and connect to the previously-stored AP. The WiFi Credentials are still intact.
You can password protect the ConfigPortal AP. Simply add an SSID as the first parameter and the password as a second parameter tostartConfigPortal. See the above examples.A short password seems to have unpredictable results so use one that's around 8 characters or more in length.The guidelines are that a wifi password must consist of 8 to 63 ASCII-encoded characters in the range of 32 to 126 (decimal)
ESP_wifiManager.startConfigPortal( SSID , password )
This gets called when custom parameters have been setAND a connection has been established. Use it to set a flag, so when all the configuration finishes, you can save the extra parameters somewhere.
ESP_wifiManager.setSaveConfigCallback(saveConfigCallback);
saveConfigCallback declaration and example
//flag for saving databool shouldSaveConfig =false;//callback notifying us of the need to save configvoidsaveConfigCallback () { Serial.println("Should save config"); shouldSaveConfig =true;}
If you need to set a timeout so theESP32 / ESP8266 doesn't hang waiting to be configured for ever.
ESP_wifiManager.setConfigPortalTimeout(120);which will wait 2 minutes (120 seconds). When the time passes, the startConfigPortal function will return and continue the sketch,unless you're accessing the Config Portal. In this case, thestartConfigPortal function will stay until you save config data or exitthe Config Portal.

SeeConfigOnSwitch example for a more complex version.
Many applications need configuration parameters likeMQTT host and port,Blynk oremoncms tokens, etc. While it is possible to useESP_WiFiManager to collect additional parameters it is better to read these parameters from a web service onceESP_WiFiManager has been used to connect to the internet.
To capture other parameters withESP_WiFiManager is a lot more involved than all the other features and requires adding custom HTML to your form. If you want to do it withESP_WiFiManager see the exampleConfigOnSwitchFS
You can set a custom IP for both AP (access point, config mode) and STA (station mode, client mode, normal project state)
This will set your captive portal to a specific IP should you need/want such a feature. Add the following snippet beforestartConfigPortal()
//set custom ip for portal//ESP_wifiManager.setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));ESP_wifiManager.setAPStaticIPConfig(WM_AP_IPconfig);
This will use the specified IP configuration instead of using DHCP in station mode.
//ESP_wifiManager.setSTAStaticIPConfig(IPAddress(192,168,0,99), IPAddress(192,168,0,1), IPAddress(255,255,255,0));ESP_wifiManager.setSTAStaticIPConfig(WM_STA_IPconfig);There are various ways in which you can inject custom HTML, CSS or Javascript into the ConfigPortal.
The options are:
- inject custom head elementYou can use this to any html bit to the head of the ConfigPortal. If you add a
<style>element, bare in mind it overwrites the included css, not replaces.
ESP_wifiManager.setCustomHeadElement("<style>html{filter: invert(100%); -webkit-filter: invert(100%);}</style>");- inject a custom bit of html in the configuration form
ESP_WMParametercustom_text("<p>This is just a text paragraph</p>");ESP_wifiManager.addParameter(&custom_text);
- inject a custom bit of html in a configuration form elementJust add the bit you want added as the last parameter to the custom parameter constructor.
ESP_WMParametercustom_mqtt_server("server","mqtt server","iot.eclipse",40," readonly");
You can filter networks based on signal quality and show/hide duplicate networks.
- If you would like to filter low signal quality networks you can tell WiFiManager to not show networks below an arbitrary quality %;
ESP_wifiManager.setMinimumSignalQuality(10);will not show networks under 10% signal quality. If you omit the parameter it defaults to 8%;
- You can also remove or show duplicate networks (default is remove).Use this function to show (or hide) all networks.

/**************************************************************************************************************************** This example will open a Config Portal when there is no stored WiFi Credentials or when a DRD is detected. You can reconfigure to use another pin, such as the convenience FLASH / BOOT button @ PIN_D0;. A password is required to connect to the Config Portal so that only who know the password can access the Config Portal. The Credentials, being input via Config Portal, will then be saved into LittleFS / SPIFFS file, and be used to connect to Adafruit MQTT Server at "io.adafruit.com" and publish a Temperature Topic Based on original sketch posted by "Marko"(https://github.com/wackoo-arduino) on https://forum.arduino.cc/index.php?topic=692108 *****************************************************************************************************************************/#if !( defined(ESP8266) || defined(ESP32) ) #error This code is intended to run on the ESP8266 or ESP32 platform!

ESP_wifiManager.setDebugOutput(false);You can also change the debugging level from 0 to 4
// Use from 0 to 4. Higher number, more debugging messages and memory usage.#define_WIFIMGR_LOGLEVEL_3
If you get compilation errors, more often than not, you may need to install a newer version of theESP32 / ESP8266 core for Arduino.
Sometimes, the library will only work if you update theESP32 / ESP8266 core to the latest version because I am using some newly added function.
If you connect to the created configuration Access Point but the ConfigPortal does not show up, just open a browser and type in the IP of the web portal, by default192.168.4.1.
