Arduino Function: EthernetUDP.begin

Description

This method initializes the ethernet UDP library and network settings.

Syntax

EthernetUDP.begin(localPort);

Parameters

localPort: the local port to listen on (int)

Returns

 1 if successful *0 if there are no sockets available to use.

Examples

#include         
#include  //If you are using Ethernet Shield 2, use instead 
#include 

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

IPAddress ip(192, 168, 1, 177);
unsigned int localPort = 8888;      // local port to listen on

// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;

void setup() {
  // starts the Ethernet and UDP:
  Ethernet.begin(mac,ip);
  Udp.begin(localPort);
}
void loop() {}
