|MAC Address and UDP
Posted: Tue Nov 16, 2021 1:07 pm
Hello my friends, I have designed a network with 5 NodeMCUs connected to a router. One of this NodeMCUs will work as master of the network, and the others are slaves. I am using UDP protocol to establish communication between the devices. My question is: How can I get the MAC Address of all the devices connected to the network? Can I obtain it from an incoming packet?? thanks for your help!!
