Hello,
I'd like o use my arduino + ethernet shield to discover certain devices in my network and query them.
If I used a pc, I'd send a ping to 255.255.255.255, wait for responses and then I'd filter by MAC address the received packets (I assume the devices I want to query have similar MAC addresses) than I'd use RARP to get the IPs.
The problem is: I don't know ho to do this with Arduino + ethernet, as I've no idea about how to manage MAC layer using the Ethernet library.
Any suggestion?
Thank you!
