I'm having problems with MQTT, how do I debug the connection?

In the Adafruit_MQTT library folder, find the file Adafruit_MQTT.h

Near the top of the file is a line:

Download File
Copy Code 
// Uncomment/comment to turn on/off debug output messages.
//#define MQTT_DEBUG

Uncomment that #define and recompile/upload your Adafruit_MQTT example to get full debug output - its *very* detailed but shows all the packets sent and received
