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.

I tried your sktech, now i get this error 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.
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
I have deleted and reinstalled the ide as well as the esp8266 core and its still one error or the other:
