I have my Core connected via usb and currently just running Tinker while I play around. Usually it can stay connected for a day or so before it loses connectivity and requires a Factory Reset to connect again.
I managed to catch it in the act of disconnecting one night and the light combination looked like this:
- Breathing Cyan
- Flashing Cyan (10 sec)
- Flashing Red (3 cycles, less than a second)
- Flashing Cyan (~5 secs)
- Flashing Green
It would stick on flashing green until a factory reset was performed. After the factory reset I am sometimes able to reconnect using the Spark CLI, sometimes it requires more than one reset to get it connected.
Is this combination of lights a clue as to what’s going on?
