Can't connect enc28j60 ethernet shield with MQTT

aymericrag · March 7, 2018, 11:33am

I everyone,

It’s my second Arduino project, the first one working with Cayenne, I use it to control two relays for my heater.
I’m using a Arduino Nano with ENC28J60 ethernet shield.

It worked pretty well for few weeks before Cayenne asked me to change to MQTT. I tried to use their generated sketch (as followed) but in the Terminal I have this answer:

[300] IP: 0.0.0.0
[300] Connecting to mqtt.mydevices.com:1883

I read many times on that the best option with this ethernet shield is to use uipethernet library but I have few errors and I don’t know how to correct it.

Does someone had the same issue and has fixed it ?
Any help will be appreciated

Thanks
Aymeric

yes have a look at this post Is ENC28J60 supported and try adding the uip library. i dont have this module to test. maybe @jcruz or @bestes can help you out with this.

Thanks for answering quickly !

I already read this post and it seems that I have the same problem than the last post from
“yilmazyurdakul”.

Before Cayenne changed to MQTT I used this sketch (power meter + relay) and it worked well.

//Cayenne
#include <UIPEthernet.h>
#include <BlynkSimpleUIPEthernet.h>
#include <CayenneDefines.h>
#include <CayenneEthernetClient.h>
#include <TimerOne.h>  
#include <SoftwareSerial.h>

#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space
#define VIRTUAL_PIN 1
#define VIRTUAL_PIN 0
#define RELAY_DIGITAL_PIN 5
#define RELAY_DIGITAL_PIN 6

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "xxxx";

//Number of pulses, used to measure energy.
long pulseCount = 0;   
//Used to measure power.
unsigned long pulseTime,lastTime, interval;

//power and energy
double power, elapsedkWh;

//Number of pulses per wh - found or set on the meter.
int ppwh = 1; //1000 pulses/kwh = 1 pulse per wh
const int ledPin = 13;
const int ldrPin = 3;

void setup()
{
    Serial.begin(115200);

    pinMode(ledPin, OUTPUT);
    pinMode(ldrPin, INPUT);
    
// KWH interrupt attached to IRQ 1 = pin3
    attachInterrupt(1, onPulse, FALLING);
    Cayenne.begin(token);
}
CAYENNE_IN(VIRTUAL_PIN)
  {
    
    // get value sent from dashboard
    int currentValue = getValue.asInt(); // 0 to 1
  
    // assuming you wire your relay as normally open
    if (currentValue == 0) {
      digitalWrite(RELAY_DIGITAL_PIN, HIGH);
    } else {
      digitalWrite(RELAY_DIGITAL_PIN, LOW);
    }
  }
  
void loop()
{
    Cayenne.run();
  }
    CAYENNE_OUT(V0)
  {
    Cayenne.virtualWrite(V0, power);
}
    CAYENNE_OUT(V1)
  {
    Cayenne.virtualWrite(V1, elapsedkWh);
}
// The interrupt routine
void onPulse()
{

//used to measure time between pulses.
lastTime = pulseTime;
pulseTime = micros();
interval = (pulseTime - lastTime);

    if (interval<20000) { // Sometimes we get interrupt on RISING
            return;
}
            //Calculate power
power = (3600000000.0 / (pulseTime - lastTime))/ppwh;

//pulseCounter
pulseCount++;

//Find kwh elapsed
elapsedkWh = (1.0*pulseCount/(ppwh*1000)); //multiply by 1000 to convert pulses per wh to kwh

}

Hi @aymericrag,

I was going to say, go to the old sketch, and modify it for MQTT.

Will need to take a closer look. Don’t know if I actually have one of these.

Cheers,

Craig

Thanks @kreggly,

I tried few things but none worked

I don’t know how to do it properly, can you help me with that ?

Cheers,

Aymeric

kreggly · March 12, 2018, 9:30pm

Hi @aymericrag,

Try the following:

Remove old Cayenne libraries from libraries directory (make a backup if you want).
Install the new one - GitHub - myDevicesIoT/Cayenne-MQTT-Arduino: Cayenne MQTT Arduino Library
Change #include <CayenneEthernetClient.h> to #include <CayenneMQTTEthernetClient.h>
Recompile.

Let us know what happens.

Cheers,

Craig

Hi @kreggly,

I tried it but unfortunately it doesn’t work, still have a lot of error message :

Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

For now I will use an ESP8266 module but it’s a shame to use Wifi for 20cm… And then I will buy a W5500 witch seems to be well suported.

Cheers,

Aymeric
