PacketRF DHCP Server

This directory contains the DHCP server implementation used by the PacketRF firmware.

The server is responsible for assigning IPv4 addresses to clients connected to PacketRF network interfaces. It integrates with the lwIP networking stack and uses PacketRF-managed IP pools for address allocation.

Implementation

The implementation is based on the DHCP server originally provided in ESP-IDF by Espressif Systems (dhcpserver.c / dhcpserver.h).

Parts of that implementation were adapted and refactored for use in PacketRF. The code was modified to integrate with:

  • the PacketRF networking architecture
  • PacketRF IP pool allocation
  • lwIP network interfaces
  • embedded constraints of the RP2350 platform

The goal of this adaptation is to provide a lightweight DHCP server suitable for embedded radio networking devices.
