- \brief
- This class provides several helper functions to generate properly
- formatted GAP Advertising and Scan Response data payloads
-
- \note
- See Bluetooth Specification 4.0 (Vol. 3), Part C, Section 11 and 18
- for further information on Advertising and Scan Response data.
-
- \par Advertising and Scan Response Payloads
- Advertising data and Scan Response data are organized around a set of
- data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
- Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
-
- \par
- Each AD type has it's own standardized 'assigned number', as defined
- by the Bluetooth SIG:
- https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile
-
- \par
- For convenience sake, all appropriate AD types have been encapsulated
- into GapAdvertisingData::DataType.
-
- \par
- Before the AD Types and their payload (if any) can be inserted into
- the Advertising or Scan Response frames, they need to be formatted as
- follows:
-
- \li \c Record length (1 byte)
- \li \c AD Type (1 byte)
- \li \c AD payload (optional, only present if record length > 1)
-
- \par
- This class takes care of properly formatting the payload, performs
- some basic checks on the payload length, and tries to avoid common
- errors like adding an exclusive AD field twice in the Advertising
- or Scan Response payload.
-
- \par EXAMPLE
-
- \code
-
- // ToDo
-
- \endcode
