ESP8266 Community Forum

- Sat Apr 25, 2015 4:05 am #15576 Hello everybody. I have a quick question. Is there a way to retrieve the ip address of the sender when receiving a UDP message? I would like to catch from the script a UDP datagram and respond to the sender so that it knows the ESP8266 exists.
A script example would be appreciated. Thanks a lot in advance.
Ciao, Alex
