ARP?
Posted: Fri Feb 15, 2019 12:03 pmHi-
I am trying to get several ESP8266's to find each other on the network. I would like the master unit to verify the secondary units by checking the ARP table to see if a given IP address matches the MAC address of a secondary unit. I have been through a bunch of the code in etharp.c and etharp.h, but a lot of it is way over my head! Does anyone have suggestions on how to do this, or some example code?
