I am using an STM32F407 MCU with RTX and UV4, and it is not responding to ARP requests, I know this because I am looking at the network traffic with wireshark. Any idea why this would be the case? I am calling main_tcpNet() frequently, so I expect to be working.
@p m.
Thank you for your reply. I set the IP address of my MCU in Net_Config.c. It is on the same sub net as my PC. Also, if I use the <arp_cache_ip> function directed at my PC (also a static IP address), I can see the ARP call and response. Again, my setup is not working when the PC initiates the ARP request.
