Arduino Function: EthernetUDP.endPacket

Description

Called after writing UDP data to the remote connection.

Syntax

UDP.endPacket();

Returns

 Returns an int: 1 if the packet was sent successfully 0 if there was an error

Examples

#include <SPI.h>
#include <Ethernet.h> //If you are using Ethernet Shield 2, use instead <Ethernet2.h>
#include <EthernetUdp.h>

//Enter a MAC address and IP address for your controller below.
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

//The IP address will be dependent on your local network:
IPAddress ip(192, 168, 1, 177);

//local port to listen on
unsigned int localPort = 8888;

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

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

void loop() {
Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
Udp.write("hello");
Udp.endPacket();
}
