So I received a beta development kit yesterday and started playing with it. I noticed that usually when a new sketch is upload to a blink, it reboots and shows rotating blue dots on its surface.
Now I have this project I wrote blindly (without having blinks) and when I try to upload it, the blink simply goes dark. Nothing happens and it does not appear it is working at all. Then if I upload a different sketch, it works again.
What may be the issue here?
Thanks in advance.
