ESP8266 UDP Send & Receive Example (Step by Step Arduino Guide)

Looking for the easiest way to send and receive data from an ESP8266? A great starting point is understanding how to configure your ESP8266 to send and receive a UDP packet.

You can use UDP to communicate with other ESP8266 devices, your computer or many other WiFi devices.

In this video we will write a simple application in the Arduino IDE that will receive a text string over UDP, print it to the serial console and then respond back with a confirmation message.

¿Como podría hacerle para enviar por UDP siendo el ESP8266 un Access Point?

for anyone else having issues -- udp.write(reply) doesn't work. instead try udp.print(reply)
