I am using an STM32f407 MCU with Keil UV4 and RTX. My application requires bidirectional UDP communication between several machines with static IP addresses and the MCU. I am running into a situation where I can communicate fine and then I suddenly can't. In those situations, I try to send data to the MCU from my computer, but wireshark shows my computer sending ARP request of the IP address of the MCU and no data. Should this be automatically resolved by calling the Main_TcpNet function often or do I also need to be purposely dealing with ARP?
Thanks in advance.
