I have been trying to run the same sketch on my Core for a couple of days now. It compiles and flashes fine, but sometime overnight, it just stops working. I receive an “Error: Function not found” when I try to call my exposed function from the cloud API. However, if I simply re-flash the firmware from the web IDE, it gets back up and running again. It happens sometime overnight. I haven’t been able to write a script to monitor for when it happens exactly. The sketch clocks in at 945 lines (with liberal spacing for readability).
I created a quick Gist at https://gist.github.com/wgbartley/8301007.
Has anyone noticed similar problems?
