Finding your core id

I didn't find any cores available via serial
Press and hold the MODE button until your core blinks solid blue

 - Is your core blinking blue?  Then press ENTER - Potentially unhandled rejection [2] No serial port identified (WARNING: non-Error used)

Steps to reproduce:

• Core plugged in but not in listen mode
• Run spark setup
• Observe error output in prompt

I had this issue today, too, but it was because I was powering the Spark from the VIN pin, so the USB cable wasn't actually connected to the Spark. 😞
