Important Note
This Blynk_WiFiManager has just been modified to create the new Blynk_Async_WM in order to use the better and more efficient ESPAsyncWebServer Library, instead of the (ESP8266)WebServer library.
The new Blynk_Async_WM is based on and sync'ed with Blynk_WiFiManager. Therefore, all the features currently supported by this Blynk_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 include file from BlynkSimpleEspxxxx_WM.h to BlynkSimpleEspxxxx_Async_WM.h.
Why do we need the new Async Blynk_Async_WM 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 extensible 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
Why do we need this Blynk_WM library
Features
This is a Blynk and WiFiManager Library for configuring/auto(re)connecting ESP8266/ESP32 modules to the best or available MultiWiFi APs and MultiBlynk servers at runtime. Connection is with or without SSL. 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 without coding knowledge. DoubleResetDetector is used to force Config Portal opening even if the Credentials are still valid.
This library is designed to help you to eliminate hardcoding your Wifi and Blynk credentials for ESP8266 and ESP32 (with/without SSL), and updating/reflashing every time you need to change them.
With version v1.6.0 or later, you can use:
New ESP8266 core v3.0.0+
With version v1.1.0 or later, you can use:
LittleFS for ESP32Multiple Reset Detection to enter Config Portal
With version v1.0.7 or later, you can configure:
Multiple WiFi Credentials (SSID, Password) and system will autoconnect to the best and available WiFi SSID.Multiple Blynk Credentials (Server, Token) and system will autoconnect to the available Blynk Servers.
With version v1.0.5 or later, you can configure:
Config Portal Static IP address, Name and Password.Static IP address, Gateway, Subnet Mask and 2 DNS Servers IP addresses.
Currently supported Boards
This Blynk_WM 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 or SPIFFS.

Blynk betaversions.ESP32 Core 2.0.0+for ESP32-based boards.ESP8266 Core 3.0.2+for ESP8266-based boards.. To use ESP8266 core 2.7.1+ for LittleFS.
ESP_DoubleResetDetector library 1.1.1+to use DRD feature. To install, check.
ESP_MultiResetDetector library 1.1.1+to use MRD feature. To install, check.
LittleFS_esp32 v1.0.6+for ESP32-based boards using LittleFS. To install, check. Notice: This
LittleFS_esp32 libraryhas been integrated to Arduino esp32 core v1.0.6+.
Installation
I) For Arduino IDE
- Be certain you have installed the most up to date version of Arduino IDE.
- Be certain you have installed the most up-to-date Blynk library.
- Using Arduino IDE,
-
either use the zip file
- Navigate to the Blynk_WiFiManager page in Github.
- Download the latest release of
Blynk_WM-master.zipand save to your hard drive. - Open Arduino IDE.
- Menu: Sketch->Include Library->Add .ZIP library…
- Select the downloaded
Blynk_WM-master.zipfile - Hit Open
- Once Arduino IDE is finished installing the library, EXIT Arduino IDE.
-
or use Arduino IDE's Library Manager
- Open Arduino IDE.
- Menu: Tools->Manage Libraries…
- Wait for library list to populate.
- Search for the keyword "Blynk". Find Blynk_WiFiManager in the library list.
- Select the latest version of the Blynk_WiFiManager library.
- Hit Install.
- Once Arduino IDE is finished installing the library, EXIT Arduino IDE.
- COPY the /certs files from the main Blynk library to the Blynk_WiFiManager library.
- Find the
Blynk/src/certslibrary directory. (This is in the main Blynk library, may be named differently.) - Find the
Blynk_WiFiManager/src/certslibrary directory. (This is in the installed Blynk_WiFiManager library, may be named differently.) Using Arduino IDE, these directories are normally found under .../Arduino/Sketchbook/libraries or .../Arduino/libraries.- (Sometimes Arduino IDE names a library folder with an unhelpful name like Arduino_12345. You can safely rename that folder under …/libraries/ to a compliant name like Blynk_WiFiManager for convenience. Remember to exit and restart IDE after renaming any library directory.)
- COPY (do not cut and paste) the entire contents of the
Blynk/src/certsdirectory to theBlynk_WiFiManager/src/certsdirectory.- (FYI: the reason for copying the certs from the Blynk library to Blynk_WiFiManager library is so that Blynk_WiFiManager will have access to Blynk's SSL certificates. And you almost certainly want to be using SSL!)
- Find the
- You must do Step 4 each time you update the Blynk_WiFiManager library to keep those SSL certs accessible.
- Open Arduino IDE. Your library is installed.
II) For VS Code & PlatformIO:
- Install VS Code
- Install PlatformIO
- Install Blynk_WM library by using Library Manager. Search for Blynk_WM in Platform.io Author's Libraries
- Use included platformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at Project Configuration File
Note for Platform IO using ESP32 LittleFS
Necessary only for esp32 core v1.0.6-
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 using LittleFS_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 latest LittleFS_esp32 v1.0.5+ to avoid the issue.
Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'
HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)
Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.
1. ESP32 has 2 ADCs, named ADC1 and ADC2
2. ESP32 ADCs functions
- ADC1 controls ADC function for pins GPIO32-GPIO39
- ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27
3. ESP32 WiFi uses ADC2 for WiFi functions
Look in file adc_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 guarantee all 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 to acquire 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 the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).
How to use
In your code, replace
-
BlynkSimpleEsp8266.hwithBlynkSimpleEsp8266_WM.hfor ESP8266without SSL -
BlynkSimpleEsp8266_SSL.hwithBlynkSimpleEsp8266_SSL_WM.hfor ESP8266with SSL -
BlynkSimpleEsp32.hwithBlynkSimpleEsp32_WM.hfor ESP32without SSL -
BlynkSimpleEsp32_SSL.hwithBlynkSimpleEsp32_SSL_WM.hfor ESP32with SSL -
For EP8266, add
#define USE_LITTLEFS true
#define USE_SPIFFS falseto use LittleFS or
#define USE_LITTLEFS false
#define USE_SPIFFS trueto use SPIFFS or
#define USE_LITTLEFS false
#define USE_SPIFFS falseto use EEPROM.
- For EP32, add
#define USE_LITTLEFS true
#define USE_SPIFFS falseto use LittleFS or
#define USE_LITTLEFS false
#define USE_SPIFFS trueto use SPIFFS or
#define USE_LITTLEFS false
#define USE_SPIFFS falseto use EEPROM.
Currently, data size in v1.1.0, with DRD/MRD and not including dynamic params, is 380 bytes from address EEPROM_START ) to save your configuration data.
EEPROM_SIZE can be specified from 512 to 4096 (2048 for ESP32) bytes.
See examples ESP32WM_Config and ESP8266WM_Config.
// Force some params in Blynk, only valid for library version 1.0.1 and later
#define TIMEOUT_RECONNECT_WIFI 10000L
#define RESET_IF_CONFIG_TIMEOUT true
#define CONFIG_TIMEOUT_RETRYTIMES_BEFORE_RESET 5To use personalized Config Portal AP SSID and Password, as well as IP Address, channel e.g. call :
// Set config portal SSID and Password
Blynk.setConfigPortal("TestPortal-ESP8266", "TestPortalPass");
// Set config portal IP address
Blynk.setConfigPortalIP(IPAddress(192, 168, 200, 1));
// Set config portal channel, default = 1. Use 0 => random channel from 1-13 to avoid conflict
Blynk.setConfigPortalChannel(0);You can specify STA-mode Static IP address, Gateway, Subnet Mask, as well as DNS server 1 and 2:
// From v1.0.5, select either one of these to set static IP
Blynk.setSTAStaticIPConfig(IPAddress(192, 168, 2, 220), IPAddress(192, 168, 2, 1), IPAddress(255, 255, 255, 0));
//Blynk.setSTAStaticIPConfig(IPAddress(192, 168, 2, 220), IPAddress(192, 168, 2, 1), IPAddress(255, 255, 255, 0),
// IPAddress(192, 168, 2, 1), IPAddress(8, 8, 8, 8));
//Blynk.setSTAStaticIPConfig(IPAddress(192, 168, 2, 220), IPAddress(192, 168, 2, 1), IPAddress(255, 255, 255, 0),
// IPAddress(4, 4, 4, 4), IPAddress(8, 8, 8, 8));Then replace Blynk.begin(...) with :
Blynk.begin()to use default DHCP hostnameESP8266-XXXXXXorESP32-XXXXXX
or to have a personalized hostname (RFC952-conformed,- 24 chars max,- only a..z A..Z 0..9 '-' and no '-' as last char)
Blynk.begin("Personalized-HostName")
in your code. Keep Blynk.run() intact.
That's it.
HOWTO Use default Credentials and have them pre-loaded onto Config Portal

Use the following code snippet in sketch
#define USE_DYNAMIC_PARAMETERS falseor
/////////////// Start dynamic Credentials ///////////////
MenuItem myMenuItems [] = {};
uint16_t NUM_MENU_ITEMS = 0;
/////// // End dynamic Credentials ///////////
6. To use custom HTML Style
const char NewCustomsStyle[] /*PROGMEM*/ = "<style>div,input{padding:5px;font-size:1em;}input{width:95%;}body{text-align: center;}\
button{background-color:blue;color:white;line-height:2.4rem;font-size:1.2rem;width:100%;}fieldset{border-radius:0.3rem;margin:0px;}</style>";
...
Blynk.setCustomsStyle(NewCustomsStyle);
7. To use custom Head Elements
Blynk.setCustomsHeadElement("<style>html{filter: invert(10%);}</style>");
8. To use CORS Header
Blynk.setCORSHeader("Your Access-Control-Allow-Origin");
9. To use and input only one set of WiFi SSID and PWD
9.1 If you need to use and input only one set of WiFi SSID/PWD
// Permit input only one set of WiFi SSID/PWD. The other can be "NULL or "blank"
// Default is false (if not defined) => must input 2 sets of SSID/PWD
#define REQUIRE_ONE_SET_SSID_PW true
But it's always advisable to use and input both sets for reliability.
9.2 If you need to use both sets of WiFi SSID/PWD
// Permit input only one set of WiFi SSID/PWD. The other can be "NULL or "blank"
// Default is false (if not defined) => must input 2 sets of SSID/PWD
#define REQUIRE_ONE_SET_SSID_PW false
10. To enable auto-scan of WiFi networks for selection in Configuration Portal
10.1 Enable auto-scan of WiFi networks for selection in Configuration Portal
#define SCAN_WIFI_NETWORKS true
The manual input of SSIDs is default enabled, so that users can input arbitrary SSID, not only from the scanned list. This is for the sample use-cases in which users can input the known SSIDs of another place, then send the boards to that place. The boards can connect to WiFi without users entering Config Portal to re-configure.
10.2 Disable manually input SSIDs
// To disable manually input SSID, only from a scanned SSID lists
#define MANUAL_SSID_INPUT_ALLOWED false
This is for normal use-cases in which users can only select an SSID from a scanned list of SSIDs to avoid typo mistakes and/or security.
10.3 Select maximum number of SSIDs in the list
The maximum number of SSIDs in the list is seletable from 2 to 15. If invalid number of SSIDs is selected, the default number of 10 will be used.
// From 2-15
#define MAX_SSID_IN_LIST 8
Important Notes for using Dynamic Parameters' ids
- These ids (such as "mqtt" in example) must be unique.
Please be noted that the following reserved names are already used in library:
"id" for WiFi SSID
"pw" for WiFi PW
"id1" for WiFi1 SSID
"pw1" for WiFi1 PW
"sv" for Blynk Server
"tk" for Blynk Token
"sv1" for Blynk Server1
"tk1" for Blynk Token1
"pt" for Blynk Port
"nm" for Board Name
Important notes
- Now you can use special chars such as ~, !, @, #, $, %, ^, &, _, -, space,etc. thanks to brondolin to provide the amazing fix in v1.0.10 to permit input special chars such as % and # into data fields. See Issue 3.
- The SSIDs, Passwords, BlynkServers and Tokens must be input (or to make them different from nothing). Otherwise, the Config Portal will re-open until those fields have been changed. If you don't need any field, just input anything or use duplicated data from similar field.
- WiFi password max length now is 63 chars according to WPA2 standard.
- Sometimes, it's hard or not possible to connect to Config Portal WiFi AP, the majority cases are caused by WiFi channel conflict if there are too many WiFi APs running around. Please use random ConfigPortal WiFi AP channel in sketch (see code snippet below) and reset the board so that another channel is used. Repeat until connection is OK
// Set config portal channel, default = 1. Use 0 => random channel from 1-13 to avoid conflict
Blynk.setConfigPortalChannel(0);Why using this Blynk_WiFiManager with MultiWiFi-MultiBlynk features
You can see that the system automatically detects and connects to the best or avaiable WiFi APs and/or Blynk Servers, whenever interruption happens. This feature is very useful for systems requiring high degree of reliability.
Moreover, this Blynk.begin() is not a blocking call, so you can use it for critical functions requiring in loop().
Anyway, this is better for projects using Blynk just for GUI (graphical user interface).
In operation, if WiFi or Blynk connection is lost, Blynk.run() will try reconnecting automatically. Therefore, Blynk.run() must be called in the loop() function. Don't use:
void loop()
{
if (Blynk.connected())
Blynk.run();
...
}just
void loop()
{
Blynk.run();
...

So, how it works?
If it cannot connect to the Blynk server in 30 seconds, no valid stored Credentials or Double Reset is detected within 10s, it will switch to Configuration Mode. You will see your built-in LED turned ON. In Configuration Mode, it starts an AP with default name ESP_xxxxxx and password MyESP_xxxxxx or configurable name and password you specified. The AP IP address is default at 192.168.4.1 or configured IP (e.g. 192.168.200.1).
First, connect your (PC, Laptop, Tablet, phone, etc.) WiFi to Config Portal AP, then enter the WiFi password :
- If you choose not to load default Credentials and Dynamic Parameters
After you connected, please, go to http://192.168.4.1 or the configured AP IP. The following Config Portal screen will appear:
- If you choose to load default Credentials and Dynamic Parameters
After you connected, please, go to http://192.168.4.1 or the configured AP IP. The following Config Portal screen will appear:
Enter your WiFi and Blynk Credentials:
1. Without SCAN_WIFI_NETWORKS
2. With SCAN_WIFI_NETWORKS
Then click Save. The system will auto-restart. You will see the board's built-in LED turned OFF. That means, it's already connected to your Blynk server successfully.

If you get compilation errors, more often than not, you may need to install a newer version of the core for Arduino boards.
Sometimes, the library will only work if you update the board core to the latest version because I am using newly added functions.

TO DO
- Fix bug. Add enhancement
DONE
- Permit EEPROM size and location configurable to avoid conflict with others.
- More flexible to configure reconnection timeout.
- For fresh config data, don't need to wait for connecting timeout before entering config portal.
- If the config data not entered completely (SSID, password, Server and Blynk token), entering config portal
- Correct the operation of BUILTIN_LED
- Modify code to be compatible with ESP8266 core pre-2.5.2.
- Add RFC952 hostname
- Add configurable Config Portal IP, SSID and Password
- Add configurable Static IP, GW, Subnet Mask and 2 DNS Servers' IP Addresses.
- Add checksum for more reliable data
- Add MultiWiFi feature to enable reconnect to the best / available WiFi AP.
- Add MultiBlynk feature to enable reconnect to the best / available Blynk Server.
- WiFi Password max length is 63, as in WPA2 standards
- Permit to input special chars such as % and # into data fields.
- Add Dynamic Parameters with checksum
- Default Credentials and dynamic parameters
- DoubleDetectDetector to force Config Portal when double reset is detected within predetermined time, default 10s.
- Configurable Config Portal Title
- Re-structure all examples to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
- Add LittleFS support to ESP8266 as SPIFFS deprecated since ESP8266 core 2.7.1.
- Add LittleFS support to ESP32 using LITTLEFS Library.
- Add support to MultiDetectDetector and MRD-related examples
- Clean-up all compiler warnings possible.
- Add Table of Contents
- Add Version String
- Add functions to control Config Portal from software or Virtual Switches.
- Add support to ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.) using EEPROM, LittleFS and SPIFFS
- Configurable Customs HTML Headers, including Customs Style, Customs Head Elements, CORS Header
- Add support to ESP32-C3 using EEPROM and SPIFFS
- Fix SSL issue with Blynk Cloud Server by using SSL in unsecured mode.
- Permit optionally inputting one set of WiFi SSID/PWD by using
REQUIRE_ONE_SET_SSID_PW == true - Enforce WiFi PWD minimum length of 8 chars
- Enable scan of WiFi networks for selection in Configuration Portal
- Drastically update code to work with either ESP8266 new breaking ESP8266 core v3.0.0+ or old core ESP8266 v2.7.4-
- Make SSL working using
BearSSL, not deprecatedaxTLS
Contributions and thanks
- Thanks to lorol for useful LittleFS_esp32 Library
- Thanks to chriskio to report AP-staying-open bug.
- Thanks to brondolin to provide the amazing fix in v1.0.10 to permit input special chars such as % and # into data fields. See Issue 3.
- Thanks to Thor Johnson and Thor Johnson in Blynk to test, find bug, suggest and encourage to add those new features in v1.0.13, such as Default Credentials/Dynamic Parms, Configurable Config Portal Title, DRD. The powerful Blynk_WM_Template is written by Thor Johnson and is included in the examples with his permission. Check these new features thanks to his direct contribution and/or enhancement requests :
- WM Config Portal using BlynkSimpleEsp32/8266_WM.h.
- How to trigger a Config Portal from code #25
- Good new feature: Blynk.resetAndEnterConfigPortal() Thanks & question #27
- Thanks to Thor Johnson and kevinleberge to help locate the bugs, discuss the USE_DEFAULT_CONFIG_DATA solution leading to release v1.0.16. See Can’t load defaults and Setting "#define USE_DYNAMIC_PARAMETERS false" on Blynk_WM_Template.ino results in compile error
- Thanks to komaneko to report bugs in Custom Blynk port not working for BlynkSimpleEsp32_Async_WM.h #4 leading to v1.3.1
- Thanks to Michael H. "bizprof". With the impressive new feature :
Enable scan of WiFi networks for selection in Configuration Portal. Check PR for v1.3.0 - Enable scan of WiFi networks #10 leading to v1.4.0
