On the photon is there an ARP cache that is accessible to us? Or some extension of Wifi.ping() that would also return the MAC of the ping’d device? I need to find a device on my network and it is DHCP as are all of my device and I not getting into the game of assigning static IPs and all that. I know the MAC OUI because the vendor registered the range they use so I just need to loop through the network and when I see that OUI to set that as a HTTP Client target IP. Any help would be much appreciated!
