Receiving UDP data from Arduino
When any packet is received it is keep in burref.
So after function who read pakets we need to check is packet received is UDP.
Some information:
IP_PROTO_P = HEX 0x17 (DEC 23)
IP_PROTO_UDP_V = HEX 0x11 (DEC 17)
We must check if in buffer possition 23 we have 17
Code:
// read packet, handle ping and wait for a tcp packet:
dat_p=es.ES_packetloop_icmp_tcp(buf,es.ES_enc28j60PacketReceive(BUFFER_SIZE, buf));
if (buf[IP_PROTO_P]==IP_PROTO_UDP_V){ // == if (buf[23]==17)
// We have UDP paket received
}
Exsample UDP packet, buffer positions and values:

Watch data flow through serial ports with Serial Watcher
Written by Super User
Serial Watcher
Serial Watcher is a small piece of program from PCRemote Control that can watch the data
flow through any of your serial ports live and save the flowing data.
It’s main use is during the testing of serial data receiver devices.

Quick way to check is
ENC28J60 Ethernet shield is present
For Ethernet shields with ENC28J60 we using this sketch for test:
----------------------------------------------------------------------------------------------------------
#include "EtherShield.h" static uint8_t mymac[6] = {0x54,0x55,0x58,0x10,0x00,0x25}; EtherShield es=EtherShield(); void setup(){ Serial.begin(9600); es.ES_enc28j60Init(mymac); } void loop(){ Serial.println(es.ES_enc28j60Revision(),HEX); delay(500); }
----------------------------------------------------------------------------------------------------------
Upload to Arduino and open Serial Monitor.
If it return zero, that would be an indication of a missing or failed shield (chip).
Our ENC28J60 chip when is connected return “6".
