ECSRadioController provides some of functions which we usually use at the laptop.
Such as Bluetooth and Wi-Fi switch.
Besides, it provieds functions that can control the brightness scenario.

In the future, we will develop a real keyboard.
Except general functions, the keyboard has additional functions(such as Bluetooth and Wi-Fi switch, mentioned previous descriptions).
The keyboard will use the functions in the ECSRadioController.

Thanks.
