Packet socket sample

Overview

This sample is a simple packet socket application showing usage of packet sockets over Ethernet. The sample prints every packet received, and sends a dummy packet every 5 seconds. The Zephyr network subsystem does not touch any of the headers (L2, L3, etc.).

Building and Running

When the application is run, it opens a packet socket and prints the length of the packet it receives. After that it sends a dummy packet every 5 seconds. You can use Wireshark to observe these sent and received packets.

See the net-tools project for more details.

This sample can be built and executed on QEMU or native_posix board as described in Networking with the host system.
