My Smart Bridge Pro started blinking. When I looked it up, I found this..
The light indicates the status of the Smart Bridge.
After powering on, the light will normally stay at a low even level. Here are some other statuses:Rotating light : this means that the Smart Bridge is automatically downloading/installing a firmware update
Rotating?? and after looking at the device again, sure enough, the LED is on the front and two sides, independently.. so they CAN make it look like it's rotating.
I've had this thing for two years and never noticed it before.. meaning this is the first update ever for me, or, I'm never looking at it at the right time
