Everything worked before, but then the device sat on the shelf for a year.
Today I turned it on, started connecting from my smartphone and the program gave a message saying update.
Connected to the PC, updated - and now S1 does not work.
When power is applied, the LED blinks once in each color and then does not light up and nothing works.
I did a "reset" of device on my PC, but it still didn't help.
From the PC, the device is visible and flashed.
So what's now?
Thank you.
