Hello everyone.
I have Microsoft Surface (Designer) Keyboard. It is connected by Bluetooth
4.0/4.1 Low Energy.
I'm having small usability issue with the device. After 10 minutes of being
idle the keyboard goes to some kind of sleep state. Later, to wake it up it
takes ~2 seconds and during this time keys pressed are ignored.
