Raw

FreeRTOS_RAW_Sockets

This repository contains addition of RAW Sockets in FreeRTOS+Plus stack.

Project example was done on Infineon XMC4500 Relax Kit over Ethernet using https://github.com/embeddedcrab/Linux_4_ARM/tree/master/ml_iot_freertos_base [FreeRTOS TCP/IP over Ethernet] as base with few modifications.

Following functionalities were added:

  1. SOCK_RAW and IPPROTO_RAW flags for RAW sockets functionality
  2. SOCK_RAW Sockets with IPPOTO_RAW & IPPROTO_UDP can act as client (example given in App/src/client_task.cpp)
  3. SOCK_RAW Sockets with IPPROTO_UDP can act as server (example given in App/src/server_task.cpp)

You can find the functionalities in App and FreeRTOS+Plus folders. [Main focus is on RAW Sockets functionality, you can ignore other things :-)]

You can see the Network capture for different cases of application for reference. Put Ip address filter as [ip.addr==192.168.1.9 || ip.addr==0.0.0.0] or can use the src and dst ip as well, can check the souce for IP addresses.

Explore it, you might find it useful.

Happy to Help & Share 😊

Cheers!!
