💬 Building a MQTT Gateway

[linkinpio]

I think I'm ussing the latest one

but as you said I don't think it will fix my issue though.
But looking at the examples I found that they have a connect function which then can be used to reconnect whenever needed not constantly like it happens now,

But not sure how I could integrate that functionality in this sketch though, as I'm not that experienced with programming :/
To you think it will be possible?

/*
 Reconnecting MQTT example - non-blocking

 This sketch demonstrates how to keep the client connected
 using a non-blocking reconnect function. If the client loses
 its connection, it attempts to reconnect every 5 seconds
 without blocking the main loop.

#include <SPI.h>
#include <Ethernet.h>
#include <PubSubClient.h>

// Update these with values suitable for your hardware/network.
byte mac[]    = {  0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
IPAddress ip(172, 16, 0, 100);
IPAddress server(172, 16, 0, 2);

void callback(char* topic, byte* payload, unsigned int length) {
  // handle message arrived
}

EthernetClient ethClient;
PubSubClient client(ethClient);

long lastReconnectAttempt = 0;

boolean reconnect() {
  if (client.connect("arduinoClient")) {
    // Once connected, publish an announcement...
    client.publish("outTopic","hello world");
    // ... and resubscribe
    client.subscribe("inTopic");
  }
  return client.connected();
}

void setup()
{
  client.setServer(server, 1883);
  client.setCallback(callback);

  Ethernet.begin(mac, ip);
  delay(1500);
  lastReconnectAttempt = 0;
}


void loop()
{
  if (!client.connected()) {
    long now = millis();
    if (now - lastReconnectAttempt > 5000) {
      lastReconnectAttempt = now;
      // Attempt to reconnect
      if (reconnect()) {
        lastReconnectAttempt = 0;
      }
    }
  } else {
    // Client connected

    client.loop();
  }

}
