Error compiling for board arduino


#1

combine two sketches (with help thanks) both sketches compile fine but new combined sketch i get error compiling for board arduino uno . The error message appears to have something to do with cayenne ethernet mqtt multiple libraries were found .
I will post error message and then my sketch below

there is an bug in this. tagging @jcruz and @bestes for this.


#3

I see a couple issues. One is that this line:

#define VIRTUAL_CHANNEL6 4

should be

#define VIRTUAL_CHANNEL6 6

otherwise it will conflict with the previously defined channel 4.

Also it appears you have two versions of the Cayenne MQTT library installed. One at C:\Users\Home Laptop\Documents\Arduino\libraries\CayenneMQTT that was probably installed via the Arduino Library Manager and one at C:\Users\Home Laptop\Documents\Arduino\libraries\Cayenne-MQTT-Arduino-master that was probably installed manually. This causes issues for the Arduino IDE so you should remove the Cayenne-MQTT-Arduino-master library folder then restart the Arduino IDE and try to compile the sketch again.
