ESP32 Forum

Hi there, I'm looking for a way to get a MAC address from an IP of another device connected to the same network, I need somehow to get to the ARP table, or send & receive ARP packages.

I saw the esp_wifi_80211_tx API and didn't see the way to get a esp_wifi_80211_rx, or anyother way to get the MAC from the IP.

Any Ideas?

You'll probably need to look into lwip functionality for this... maybe etharp_get_entry() does what you want?
