7Overview
8********
9
10This simple application is a usage example to manage HCI VS commands to obtain
11scan request events even using legacy advertisements, while may result in lower
12RAM usage than using extended advertising.
13This is quite important in applications in which the broadcaster role is added
14to the central role, where the RAM saving can be bigger.
15This sample implements only the broadcaster role; the peripheral role with
16connection can also be added, depending on configuration choices.

21* A board with Bluetooth LE support
22* A central device & monitor (e.g. nRF Connect) to check the advertiments and
23  send scan requests.
