Why do we need this Blynk_Async_WM library
This is a Blynk and WiFiManager Library, using ESPAsyncWebServer instead of (ESP8266)WebServer, 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.
Thanks to this Blynk_Async_WM library is based on and sync'ed with Blynk_WM library
, all the features currently supported by Blynk_WM library
will be available. Please have a look at DONE
or DONE in Blynk_WM library
for those too-many-to-list features.
- 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
This BlynkESP32_BT_WF library currently supports these following boards:
- ESP32 using EEPROM, SPIFFS or LittleFS.
- ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.) using EEPROM
- ESP8266 using EEPROM, SPIFFS or LittleFS.
- Configurable Customs HTML Headers, including Customs Style, Customs Head Elements, CORS Header.

These are instructions demonstrating the steps to install esp32-s2 core on Ubuntu machines. For Windows or other OS'es, just follow the the similar principles and steps.
Assuming you already installed Arduino IDE ESP32 core and the installed directory is
/home/your_account/.arduino15/packages/esp32
First, copy the whole original esp32 core to another safe place. Then delete all the sub-directories of
/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4
Download esp32-s2 core in the zip
format:
arduino-esp32-esp32s2.zip
Copy all subdirectories of esp32-s2 core into /home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4
Download esp32-s2 Toolchain corresponding to your environment (linux-amd64, win64, etc.).
For example xtensa-esp32s2-elf-gcc8_4_0-esp-2020r3-linux-amd64.tar.gz
, then un-archive.
Download esptool int the zip
format:
esptool-3.0.zip
Copy whole xtensa-esp32s2-elf
directory into /home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4/tools
Rename esptool-3.0
directory to esptool
Copy whole esptool
directory into /home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4/tools
If you haven't installed a new version with WebServer.handleClient delay PR #4350 or haven't applied the above mentioned PR, you have to use the following patch.
To be able to run Config Portal on ESP32-S2 boards, you have to copy the files in esp32-s2 WebServer Patch directory into esp32-s2 WebServer library directory (~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer).
Supposing the esp32-s2 version is 1.0.4, these files WebServer.h/cpp
must be copied into the directory to replace:
~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.h
~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.cpp
That's it. You're now ready to compile and test for ESP32-S2 now
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'
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.
- ADC1 controls ADC function for pins GPIO32-GPIO39
- ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27
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 migrate from Blynk_WM library
In your code, just replacing
BlynkSimpleEsp8266_WM.h
withBlynkSimpleEsp8266_Async_WM.h
for ESP8266without SSL
BlynkSimpleEsp8266_SSL_WM.h
withBlynkSimpleEsp8266_SSL_Async_WM.h
for ESP8266with SSL
BlynkSimpleEsp32_WM.h
withBlynkSimpleEsp32_Async_WM.h
for ESP32without SSL
BlynkSimpleEsp32_SSL_WM.h
withBlynkSimpleEsp32_SSL_Async_WM.h
for ESP32with SSL
In your code, replace
BlynkSimpleEsp8266.h
withBlynkSimpleEsp8266_Async_WM.h
for ESP8266without SSL
BlynkSimpleEsp8266_SSL.h
withBlynkSimpleEsp8266_SSL_Async_WM.h
for ESP8266with SSL
BlynkSimpleEsp32.h
withBlynkSimpleEsp32_Async_WM.h
for ESP32without SSL
BlynkSimpleEsp32_SSL.h
withBlynkSimpleEsp32_SSL_Async_WM.h
for ESP32with SSL
- For EP8266, add
#define USE_LITTLEFS true
#define USE_SPIFFS false
to use LittleFS or
#define USE_LITTLEFS false
#define USE_SPIFFS true
to use SPIFFS or
#define USE_LITTLEFS false
#define USE_SPIFFS false
to use EEPROM.
- For EP32, add
#define USE_LITTLEFS true
#define USE_SPIFFS false
to use LittleFS or
#define USE_LITTLEFS false
#define USE_SPIFFS true
to use SPIFFS or
#define USE_LITTLEFS false
#define USE_SPIFFS false
to use EEPROM.
Currently, data size, with DRD 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 Async_ESP32WM_Config and Async_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 5
To 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:
// 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-XXXXXX
orESP32-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.

- 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
- Now you can use special chars such as ~, !, @, #, $, %, ^, &, _, -, space,etc. thanks to brondolin to provide the amazing fix 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_Async_WM 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();
...
}

If it cannot connect to the Blynk server in 30 seconds, no valid stored Credentials or Double Reset is detected within default abd configurable 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 :

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();
...
}
The following is the sample terminal output when running example Async_ESP32_MultiTask to demonstrate the displaying and measuring tasks still work when the WiFi and Blynk are lost and the system is busy reconnecting to WiFi and Blynk. See the issue in Blynk + LCD + WiFi Manager if not using MultiTask in that case.

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.
- Configurable Customs HTML Headers, including Customs Style, Customs Head Elements, CORS Header.
- Add support to ESP32-S2 (ESP32-S2 Saola and AI-Thinker ESP-12K). Currently using EEPROM only. To add support to LittleFS and SPIFFS in future releases.
- Fix Config Portal Bug.
- Tested with Latest ESP32 Core 1.0.5 for ESP32-based boards.
- Update examples
- To permit auto-reset after configurable timeout if DRD/MRD or non-persistent forced-CP. Check Good new feature: Blynk.resetAndEnterConfigPortal() Thanks & question #27
- Fix rare Config Portal bug not updating Config and dynamic Params data successfully in very noisy or weak WiFi situation
- Add functions to control Config Portal from software or Virtual Switches. Check How to trigger a Config Portal from code #25
- Add examples to demo the new Virtual ConfigPortal SW feature
- Optimize code
- Add support to LittleFS for ESP32 using LITTLEFS Library
- Add support to MultiDetectDetector. MultiDetectDetector feature to force Config Portal when configurable multi-reset is detected within predetermined time.
- Clean-up all compiler warnings possible.
- Add Table of Contents
- Modify Version String
- Add MRD-related examples.
