- This is the new library, adding to the current Blynk_WiFiManager. It’s designed to help you eliminate
hardcodingyour Blynk credentials for Mega/Teensy boards running ESP8266 AT shields, and updating/reflashing every time when you need to change them. - You can update WiFi and Blynk Credentials any time you need to change via Configure Portal. Data are saved in configurable locations in EEPROM.
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 portal, default called Teensy4_XXXXXX or Mega_XXXXXX. Connect to it using password Teensy4_XXXXXX or MyMega_XXXXXX.
After you connected, please, go to http://192.168.4.1 or the AP IP you specified.
Enter your credentials, then click Save. After you restarted, it’ll try to connect to your WiFi and Blynk server.

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();
...
}
Releases v1.0.0
Features
- This release of very-easy-to-use will help you to eliminate hardcoding your Wifi and Blynk credentials for Mega/Teensy boards running ESP8266 AT shields, and updating/reflashing every time when you need to change them.
- Configuration data are stored in configurable location in EEPROM.
- When WiFi and/or Blynk connection is lost, the WM will try auto-reconnect.
