Wi-Fi/Z-Wave Long Range (LR) Bridge Gateway

This project demonstrates a Wi-Fi/Z-Wave Long Range (LR) bridge gateway. The gateway acts as a bridge between Z-Wave devices and TLS servers, enabling communication and control via a TLS socket connection.

Hardware requirements

• BRD4002A Mainboard + BRD4342A Radio Board (SiWx917 Bridge)
• BRD4002A Mainboard + EFR32xG23 Radio Board (Z-Wave NCP Controller)
• BRD4001A Mainboard + EFR32xG23 Radio Board (Z-Wave End Device)

Hardware Setup

Connect UART_TX, UART_RX, and GND from the Expansion Header on the Z-Wave NCP Controller board to P33 (UART_TX), P35 (UART_RX), and GND on the SiWx917 Bridge, respectively.
