How to configureWiz550S2E/Wiz550WEB using WIZnet Configuration Tool


This post introduces the usage of configuration tool for WIZnet Product  Wiz550S2E / Wiz550WEB. This configuration tool provides two ways to configure our product in GUI mode and Command line mode, so users can choose a way depending on their convenience.

For example, if you want to test several functions or changes on a product, then GUI mode would be a better choice. In the other hand, if you want to update same information of multiple products in factory repeatedly, then Command line mode would be much better and convenient.

This post will shows how to use the configuration tool in GUI mode and Command line mode.

Before starting, refer following link for creating runnable jar file for our source code.

Exporting Runnable Jar from project for WIZnet Configuration Tool


Gui Mode

In order to use GUI mode, execute runnable jar without arguments



  1. Connect modules which will be configured
  2. Click [Search] to find connected modules.
  3. Run other functions as you need.
    • Setting : update changed information
    • F/W Uploading : upload firmware using TFTP server
    • Reset : reset module
    • Factory Reset : reset module as factory setting

Command Line Mode

When you want to configure modules in Console Mode, then use argument with runnable jar file in command line.

Search Modules


-b : search available modules and display found modules

Firmware Upload


-m : designate mac address

-f : firmware filename to be uploaded on module

-s : TFTP server address

-t : TFTP server port [default:69]

-p : setting password of module

to upload new firmware on module, the module has to be set up with correct network information (and TFTP server should be reachable).

e.g) If TFTP server address is

Module’s IP should be 192.168.111.*


Functions with parameters

[Application Example] Wi-Fi Geolocation Clock


This post introduces an application example about how to identify my current location by connecting (Geolocation) Server using WizFi250 and WIZwiki-W7500, and getting time through NTP(Network Time Protocol) Server.


System Configuration


Hardware Requirements




  • SSD1306 OLED : 128 x 64 dot matrix panel


Hardware Configuration

UART0 RX/TX/CTS/RTS pins of WIZwiki-W7500 board are used to control WizFi250 which Wi-Fi module and It use I2C SDA/SCL pins for using SSD1306 OLED.



Compilation of WizFi250 Geolocation and NTP Example

You can use this WizFi250 Geolocation and NTP example in following link.

WizFi250 Geolocation_NTP Example


Libraries for this example

SSD 1306 Library

To make use of SSD1307 OLED, you need Adrifruit GFX Library. I found some minor bugs using Display() function, so I asked Pull Request to library’s owner.

HTTP Client

As you easily can know by name, HTTP Client Library is used for sending request to and/or receiving response from external web server. In this example, it is used to get Geolocation(Geological code) by connecting to server. If you connect to, then you can get name of country, address, latitude, longitude, TimeZone and so on, in (*.csv) format.


NTP Client

NTP Client Library is used to get UTC from Network Time Server by using UDP commnucation. This example uses a NTP Server Domain( in South Korea. The information acquired from NTP Server is UTC, so 9 hours should be added to get the local time in South Korea.
