Ethernet Manager for Mega/UNO/Nano with Ethernet W5X00 board

This is the new library, adding to the current Blynk_WiFiManager. It’s designed to help you eliminate hardcoding your Blynk credentials in Mega/UNO/Nano boards using with Ethernet board (W5100, W5200, W5500, etc). It’s currently not supporting SSL because there is not enough memory in Mega, UNO, Nano boards. You can update Blynk Credentials any time you need to change via Configure Portal. Data are saved in configurable locations in EEPROM.

So, how it works?

If no valid config data are stored in EEPROM, it will switch to Configuration Mode. Connect to access point at the IP address displayed on Terminal or Router’s DHCP server as in the following picture:

Selection_1

After you connected to, for example, 192.168.2.86, the Browser will display the following picture:

Selection_2

Enter your credentials (Blynk Server and Port). If you prefer static IP, input it (for example 192.168.2.79) in the corresponding field. Otherwise, just leave it blank or nothing.

Selection_3

Then click Save. After the board auto-restarted, you will see if it’s connected to your Blynk server successfully as in the following picture:
