14 years agoYeah it's in the LwIP/FreeRTOS port I wrote, but it uses the socket interface so it will only work if you use that. What it basically does, is sending an ICMP ping packet to the target. What you could do is write a function which sends an UDP packet to the requested target and then start processing the input for a while. When 10ms (in case of slow networks) or so has passed the target's mac is probably in your ARP table ready to be found :)
