Project description

How Does nRF9160 Use W5500 to Bridge Ethernet Devices to LTE? Overview This project introduces an LTE Ethernet Gateway built with Nordic nRF9160 and WIZnet W5500. The project was created as a sample program that allows communication devices connected on the Ethernet side to access a server through LTE. In this architecture, W5500 provides the Ethernet interface on the LAN side, while nRF9160 provides the LTE-M / NB-IoT cellular uplink. The key concept is simple: an Ethernet device connects to the gateway through W5500, and the gateway forwards communication to the server through LTE. This…
