First attempt at mqtt not compiling


#1

Hi guys, this is my first attempt at using mqtt with the esp8266 and i havent’ been able to get compile the cayenne mqtt sketch for the past few hours. i get this error below
I’m using a wemos nodemcu with oled screen.
any idea what the problem could be from my error log?

Build options changed, rebuilding all

@aotrakstar use this code and make sure you have CayenneMQTT library installed.

// This example shows how to connect to Cayenne using an ESP8266 and send/receive sample data.
// Make sure you install the ESP8266 Board Package via the Arduino IDE Board Manager and select the correct ESP8266 board before compiling. 

//#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.h>

// WiFi network info.
char ssid[] = "ssid";
char wifiPassword[] = "wifiPassword";

// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username[] = "MQTT_USERNAME";
char password[] = "MQTT_PASSWORD";
char clientID[] = "CLIENT_ID";

unsigned long lastMillis = 0;

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

void loop() {
	Cayenne.loop();

	//Publish data every 10 seconds (10000 milliseconds). Change this value to publish at a different interval.
	if (millis() - lastMillis > 10000) {
		lastMillis = millis();
		//Write data to Cayenne here. This example just sends the current uptime in milliseconds.
		Cayenne.virtualWrite(0, lastMillis);
		//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("CAYENNE_IN_DEFAULT(%u) - %s, %s", request.channel, getValue.getId(), getValue.asString());
	//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError("Error message");
}

I tried your sktech, now i get this error :slight_smile:C:\Users\w4r10ck3r\Documents\AVIS\cayenne_esp8266_mqtt\cayenne_esp8266_mqtt.ino:6:32: fatal error: CayenneMQTTESP8266.h: No such file or directory

I am positive that the CayenneMQTTESP8266.h file is present in the library.

Hello,
Where is CayenneMQTTESP8266.h located ? This sketch should compile without errors .


#5

My bad… it failed to compile since because i had downloaded the arduino mqtt zip file instead of the esp8266. So i no longer get that error. this is the new error while compiling

C:\Users\w4r10ck3r\Documents\Arduino\libraries\ESP8266WiFi\src\ESP8266WiFiSTA.cpp:623:14: error: ‘WPS_CB_ST_UNK’ was not declared in this scope


#6

Sounds like that error is caused by not having the board installed in the IDE Follow these instructions to get that installed and let us know if it works!


#7

The installation instruction link is dead.


#8

Works for me, try this one https://github.com/esp8266/Arduino


#9

I have deleted and reinstalled the ide as well as the esp8266 core and its still one error or the other:

C:\Users\w4r10ck3r\Documents\Arduino\libraries\Cayenne-MQTT-ESP-master\src/CayenneArduinoMQTTClient.h:46:7: note: no known conversion for argument 1 from ‘WiFiClient’ to ‘int&’


#10

Can you post the code you are using?

i have same problem

help me please
