[718830] MQTT connect failed, error -1
[750286] MQTT connect failed, error -1
[781828] MQTT connect failed, error -1

I deleting and adding new widget multiple times also change channel numbers the data is change but previous value doesn’t store in my dashboard.

now again come Network connection failed problem

this is my code

#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.h>
float Temperature=0;
float Humidity=0;
#include <Wire.h>
#include “ClosedCube_HDC1080.h”

ClosedCube_HDC1080 hdc1080;

char ssid = “xxxxx”;
char wifiPassword = “yyyyyyy”;

void setup()
{
Serial.begin(9600);
Serial.println(“ClosedCube HDC1080 Arduino Test”);
hdc1080.begin(0x40);
Cayenne.begin(username, password, clientID, ssid, wifiPassword);
}

void loop()
{
Serial.print(“T=”);
Temperature=hdc1080.readTemperature();
Serial.print(Temperature);
Serial.print(“C, RH=”);
Humidity=hdc1080.readHumidity();
Serial.print(Humidity);
Serial.println(“%”);
delay(1000);
Cayenne.virtualWrite(V1, Temperature);
Cayenne.virtualWrite(V2, Humidity);
Cayenne.loop();
}

please help me to solve this problem

Hi,

Did you click the plus sign when adding the widget? Also, dont post your MQTT credentials on the forums.

10

change this

to

  unsigned long lastMillis = 0;
  if (millis() - lastMillis > 10000) {
    lastMillis = millis();
Cayenne.virtualWrite(V1, Temperature);

Cayenne.virtualWrite(V2, Humidity);
  }

again come network connection problem. am missing any function for network connectivity???

[211099] Network connect failed
[219123] Network connect failed
[227123] Network connect failed

12

did you try the above code? can you post the entire code you are using.

13

it’s pehaps a wifi connection failed instead of “Cayenne Failed” ?
Add this somewhere in LOOP :

  int i = 0;
  while (WiFi.status() != WL_CONNECTED && i < 50) {
    delay(500);
    i++;
    Serial.print(".");
  }
  if (WiFi.status() != WL_CONNECTED) {
    Serial.println("WiFi Connection failed, restart");// echoué = reset
    WiFi.disconnect();
    ESP.restart();
  }

Cayenne.virtualWrite(V2, Humidity);
}
}
some times server connected data show Value Display Widget, but chart not updating current data with previous days .

most of Cayenne server disconnected
[340006] Network connect failed
[348131] Network connect failed
[356180] Network connect failed

this error mostly come

this is mostly because of the error with wifi connection. can you try connecting to another wifi if you have or to your mobile hotspot.
