My board based on e-series 3G has this weird behaviour on startup, system in automatic mode and empty setup() and loop():
- Green LED flash for 1-2mins
- White flash for a few seconds
- Green flash for 1-2min
- Blue (connected)
Sometimes the device fails to connect and it keeps looping 1-3
Yet, if I press reset a few seconds after 1. the devices reboot itself and connects to cloud (blue light) very quickly (1-10seconds).
