Hi All,

Just started getting some odd behavior out of my Robot Inventor hub. The big center button never used to flash much at me, but now it is. Flashes orange twice, then bluish-white once. Takes abut one second to do those three flashes. Then does it again, and again etc. If I try to run a program (hub is connected by cable to my computer), it runs the program correctly... while the center button keeps flashing orange as described.

If I hold the center button down, it quietly clicks at me three times in the normal shutdown sequence, then shuts down. Except the center button keeps flashing. Now orange twice, off for maybe 1/2 second, then orange twice more etc.

Has anybody seen this before? What could be causing it?

-----------------------------------

A little more: When I unplug the cable and then long-press the center button, the hub powers down as expected.... and now the center button's light goes out and stays out. At that point the hub looks simply powered down, with no lights on, none flashing etc., perfectly normal. 

Then when I plug the cable in (computer and hub), the hub powers up as expected... and the center light starts its one-white-two-orange flashing again. The tiny "charge" light is on also, red, meaning the battery needs more charge.

I'll let it charge overnight and see if its behavior changes.

It means the battery is low.

Thank you, David, you are right! I plugged it in all night. Next morning, I ran several programs on it, powered up and down a few times, never saw a single orange flash.
