@file  app_peripheral.c

@brief This example file demonstrates how to activate the peripheral role with
the help of BLEAppUtil APIs.

Two structures are used for event handling, one for connection events and one
for advertising events.
In each, eventMask is used to specify the events that will be received
and handled.
In addition, fill the BLEAppUtil_AdvInit_t structure with variables generated
by the Sysconfig.

In the events handler functions, write what actions are done after each event.
In this example, after a connection is made, activation is performed for
re-advertising up to the maximum connections.

In the Peripheral_start() function at the bottom of the file, registration,
initialization and activation are done using the BLEAppUtil API functions,
using the structures defined in the file.

More details on the functions and structures can be seen next to the usage.
