@kennethlimcp sry forgot to mention it was Apple router. I left it for 30 minutes or so near the router and when came back it was breathing cyan. And can’t be sure about u.Fl one as I gave it to my brother. So I should ask him first, but for sure he attached to it a good self made antenna
and yes the core was blinking blue.
@war1st is it connected to the cloud now?
You should only end up with:
- blinking green
- blinking cyan
- breathing cyan
as the most common encounters which usually resolve with a reset. Other cases are rare 
@kennethlimcp yes it is breathing cyan now and connected to the cloud.
