# TTGO T-Beam W5500 Lite

> This project is aimed at addressing the problem of sending downstream messages in LoRaWAN.

Original author: Aimee (source: https://github.com/technopolistv/TTGO-T-Beam-W5500-Ethernet)

## Components

- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

This project is intended to address the issue of LoRaWAN's downlink message transmission, and aims to implement a system that processes messages quickly and sends them at downlink frequencies instead of the time-constrained approach of the LoRaWAN Semtech Packet Forwarder Protocol.

Built a downstream message service using an Arduino Uno, Ethernet Shield, and LoRa breakout board. Additionally, utilized an ESP32-based TTGO T-Beam board.

Using the ESP32 chip, I provide internet connectivity via Ethernet and transmit downstream messages through a LoRa module. Additionally, I concurrently utilize the Arduino Ethernet, arduino-LoRa, and PubSubClient libraries for testing and example purposes.
