Ethernet : UDP.beginPacket()
Description
Starts a connection to write UDP data to the remote connection
Syntax
UDP.beginPacket(remoteIP, remotePort);
Parameters
remoteIP: the IP address of the remote connection (4 bytes)
remotePort: the port of the remote connection (int)
Returns
None
Example
#include <SPI.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
// 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() {
// 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();
}
