Error on New Library


Hi, thanks for new lib guys but i can’t verify this code:

#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space
#include <CayenneMQTTESP8266Shield.h>

char ssid[] = "";
char wifiPassword[] = "";

char username[] = "";
char password[] = "";
char clientID[] = "";

#define EspSerial Serial1

ESP8266 wifi(&EspSerial);

void setup()


  Cayenne.begin(username, password, clientID, wifi, ssid, wifiPassword);

void 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.
  // 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_LOG("Channel %u, value %s",, getValue.asString());
  //Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError("Error message");

It is giving this error:


This example uses the Serial1 hardware serial pins available on the Mega. You can also try
using a software serial, though it may be less stable.


Okay i will use in Mega. Thanks


you can also use uno but connect esp8266 with software serial.
