Ethernet test on M-Duinos PLUS version

Ethernet test on M-Duinos PLUS version

In this post it is showed how to test Ethernet communication on M-Duino PLUS version

It’s necessary to install Arduino Ethernet2 library. See more infromation about Ethernet library functions on Arduino Reference.

Connecting an M-Duino to a router through Ethernet and uploading the test sketch, the M-Duino is able to complete the test.  

Next is showed the code:

#include <Ethernet2.h>
#include <SPI.h>
byte _mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xEA };
byte _ip[] = {10, 20, 30, 15};
byte _server[] = {216, 58, 201, 132};

void setup() {
  Serial.println("mduino-plus Ethernet test started");
  Ethernet.begin(_mac, _ip);
  Serial.print("IP: ");

void loop() {
EthernetClient client;
if (client.connect(_server, 80)) {
  Serial.println("Ethernet OK");
} else {
  Serial.println("Ethernet FAIL");
