- **WIZnet W55RP20-EVB-Pico** x 1 ([docs](https://wiznet.io/products/powered-by-raspberry-pi/w55rp20-evb-pico))

## Article

Hello everyone,

Today, I'd like to share how to use the **W55RP20-EVB-PICO** with the **WIZnet S2E Configuration Tool**.

### Project Overview

This project is still a work in progress and will be updated continuously. Our ultimate goal is to enable users to search and manage WIZnet's S2E (Serial to Ethernet) devices using only the W55RP20-EVB-PICO, without the need for a PC.

### Background

Among WIZnet's S2E devices, those that use the **RP2040**, **W7500(P)**, and **W55RP20** all receive and respond to the Config command on port **50001**. (The Config command is identical to the AT command; please refer to the documentation[link](https://docs.wiznet.io/Product/ioNIC/W55RP20/W55RP20-S2E/command-manual-en)for more details.)

This behavior is documented in WIZnet's official materials. You can also confirm it by using Wireshark to monitor the device search process performed by the Config Tool.

### Sending Config Commands from W55RP20-EVB-PICO

What this means is that if we send the same packet from the **W55RP20-EVB-PICO**, the S2E devices will respond accordingly.

- **Packet Details**: We send a config command to the UDP broadcast port **50001** as shown below.

- **Device Response**: The S2E devices respond to this command with their information.

- **Data Parsing**: By parsing the received packets for the MAC address, firmware version, device name, and IP mode, and displaying them in the terminal, we can confirm successful communication, as shown in the example output below.

### Future Plans

We plan to enhance this project by:

- **Parsing More Data**: Extracting additional information from the response packets.

- **LCD Display**: Displaying the parsed data on an LCD screen connected to the W55RP20-EVB-PICO.

- **Standalone Device Management**: Allowing users to search and manage WIZnet's S2E devices using only the W55RP20-EVB-PICO, eliminating the need for a PC.

By achieving these goals, we aim to provide a more convenient and efficient way to manage S2E devices in various applications.

Thank you for your interest. Stay tuned for future updates!
