Cant connect to adafruit IO, Exception 3

by blaablaaguy on Sun Dec 30, 2018 5:35 am

Tried to run the publish example after reverting to ver 4.2.4 of the esp8266 board manager, and it compiles now.
However, when I upload and run the code to my board I get the following error in the serial monitor which endlessly repeats itself over and over. I did a couple of searches and most cases of this seems to be caused by dropping support for PROGMEM, but im running the latest example that as far as I can see, doesnt include this, so im not really sure what to do from here.

I don't have a specific explanation for the error you're seeing, but I highly recommend installing the ESP Exception Decoder tool if you're using the Arduino app. That exception and stack trace should point to the specific line of code that's causing the error, but it's dependent on your project for interpretation. i.e., I can't copy it to my machine and tell you where your code raised the exception.

If you're not able to get it running, are you able to run any of the Adafruit IO example sketches?
