This is a Blynk and WiFiManager Library for configuring/auto(re)connecting ESP8266/ESP32-AT-command shields/modules to the available MultiWiFi APs at runtime. Connection is without SSL. Configuration data to be saved in either EEPROM, nRF52/RP2040 LittleFS, SAMD EEPROM-emulated FlashStorage, SAM-DUE DueFlashStorage or STM32 emulated 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 boards using ESP8266/ESP32-AT-command shields, and updating/reflashing every time you need to change them via Config Portalor or sketch.
The RP2040-based boards, such as RASPBERRY_PI_PICO, are currently supported using Earle Philhower's arduino-pico core v1.4.0+ with Blynk/WiFiManager features thanks to LittleFS support.
The support to Arduino-mbed RP2040 core with Blynk/WiFiManager features will be added in the future using simulated-EEPROM or LittleFS if ready then. Now you can use this core without Blynk/WiFiManager features.

Test before using different AT-Firmware Version at your own risks. Just use any simple example to verify if the AT-firmware is OK.
Compatible AT-Firmare version will be updated. Check for all supported AT Firmwares and download them from AT_Firmwares.
Support to ESP32-AT-command shields has been added to permit using new library ESP_AT_Lib to replace Blynk's BlynkESP8266_Lib. The same ESP_AT_Lib can also be use for ESP8266-AT shields.
The best and easiest way is to use Arduino Library Manager
. Search for Blynk_Esp8266AT_WM
, then select / install the latest version.
You can also use this link for more detailed instructions.
Then copy BlynkDetectDevice.h to folder ~/Arduino/libraries/Blynk/src/Blynk to overwrite the original file BlynkDetectDevice.h
.
Another way to install is to:
Blynk_Esp8266AT_WM-master.zip
.Blynk_Esp8266AT_WM-master
directory Blynk_Esp8266AT_WM-master/src
folder to Arduino libraries' directory such as ~/Arduino/libraries/
.Then copy BlynkDetectDevice.h to folder ~/Arduino/libraries/Blynk/src/Blynk
to overwrite the original file BlynkDetectDevice.h
. By doing this, the correct board type can be displayed correctly along with Blynk logo as follows:
___ __ __
/ _ )/ /_ _____ / /__
/ _ / / // / _ \/ '_/
/____/_/\_, /_//_/_/\_\
/___/ v0.6.1 on NRF52840_ITSYBITSY_EXPRESS
not just unknown Arduino board type:
___ __ __
/ _ )/ /_ _____ / /__
/ _ / / // / _ \/ '_/
/____/_/\_, /_//_/_/\_\
/___/ v0.6.1 on Arduino
To be able to compile, run and automatically detect and display BOARD_NAME on nRF52840/nRF52832 boards, you have to copy the whole nRF52 Packages_Patches directory into Adafruit nRF52 directory (~/.arduino15/packages/adafruit/hardware/nrf52/1.1.0).

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
// Set config portal channel, default = 1. Use 0 => random channel from 1-13 to avoid conflict
Blynk.setConfigPortalChannel(0);
You can see that the system automatically detects and connects to the avaiable WiFi APs, 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, it will switch to Configuration Mode
. You will see your built-in LED turned ON. In Configuration Mode
, it starts a configurable access point, default called nRF52_XXXXXX
, SAMD_XXXXXX
, DUE_XXXXXX
,Mega_XXXXXX
or STM32_XXXXXX
. Connect to it using password MynRF52_XXXXXX
, MySAMD_XXXXXX
, MyDUE_XXXXXX
, MyMega_XXXXXX
or MySTM32_XXXXXX
.
After you connected, please, go to http://192.168.4.1 or the AP IP you specified.
Enter your credentials : WiFi SSID/Password, Blynk Server, Port and Token, Board Name.
Then click Save
. After you restarted, you will see your built-in LED turned OFF. That means, it 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 board's core, ESP8266 AT shield
AT-command or this library version.
Sometimes, the library will only work if you update the ESP8266 AT shield
core to the newer or older version because some function compatibility.
