Original C example: Bluetooth - SoC Empty

This example is almost empty. It implements a basic application to demonstrate how to handle events and how to use the GATT database.

• A simple application is implemented in the event handler function that starts advertising on boot (and on connection_closed event). As a result, remote devices can find the device and connect to it.

• A simple GATT database is defined by adding Generic Access and Device Information services. As a result, remote devices can read basic information, such as the device name.
