My arduino with ethernet sheild W5100 cannot connect to cayenne


#1

My devices : Arduino Mega 2560 with W5100 ethernet shield

Web Dashboard

this is my code .

/*
This example shows how to connect to Cayenne using an Ethernet W5100 shield and send/receive sample data.

The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.

Steps:

  1. Set the Cayenne authentication info to match the authentication info from the Dashboard.
  2. Compile and upload the sketch.
  3. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.

//#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <CayenneMQTTEthernet.h>

// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username[] = “xxxxxxxxxxxxxxxxxxxxxxxxx”;
char password[] = “xxxxxxxxxxxxxxxxxxxxxxxxx”;
char clientID[] = “xxxxxxxxxxxxxxxxxxxxxxxxx”;

void setup() {
Serial.begin(9600);
Cayenne.begin(username, password, clientID);
}

void loop() {
Cayenne.loop();
}

// Default function for sending sensor data at intervals to Cayenne.
// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.
CAYENNE_OUT_DEFAULT()
{
// Write data to Cayenne here. This example just sends the current uptime in milliseconds on virtual channel 0.
Cayenne.virtualWrite(0, millis());
// Some examples of other functions you can use to send data.
//Cayenne.celsiusWrite(1, 22.0);
//Cayenne.luxWrite(2, 700);
//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);
}

// Default function for processing actuator commands from the Cayenne Dashboard.
// You can also use functions for specific channels, e.g CAYENNE_IN(1) for channel 1 commands.
CAYENNE_IN_DEFAULT()
{
CAYENNE_LOG(“Channel %u, value %s”, request.channel, getValue.asString());
//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError(“Error message”);
}

uncomment this //#define CAYENNE_DEBUG and check your serial monitor for any error. post a screenshot of your serial monitor.

Hi guys,

I got a similar problem as realplastic01 and I am using the exact same Hardware.

Are there any special settings I have to set on my internet connection?

Thanks!
