You can install directly from Arduino Library Manager
To 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 saved in configurable location in EEPROM.
With version `v1.0.0` or later, you now can configure:
1. `Config Portal Static IP address, Name and Password.`
2. `Static IP address, Gateway, Subnet Mask and 2 DNS Servers IP addresses.`
This is the library designed to help you eliminate hardcoding your WiFi and Blynk Credentials in Teensy (3.x, 4.0) and Arduino Mega 1280, Mega 2560 boards using ESP8266 AT-command WiFi shields.
You can update Blynk Credentials any time you need to change via Configure Portal. Data are saved in configurable locations in EEPROM.
This is the link to Blynk
Blynk was designed for the Internet of Things. It can control hardware remotely, it can display sensor data, it can store data, visualize it and do many other cool things.
You can install and use Local Blynk Server (RPi Zero W, 3B+, 4, Laptop, PC, etc) to have full control.
The Server source code is in Public Domain and written in Java. You can download, compile and use to be sure having full control.
