bryantaylor 0:eafc3fd41f75 28 * @brief This class provides several helper functions to generate properly
bryantaylor 0:eafc3fd41f75 29 * formatted GAP Advertising and Scan Response data payloads.
bryantaylor 0:eafc3fd41f75 30 *
bryantaylor 0:eafc3fd41f75 31 * @note See Bluetooth Specification 4.0 (Vol. 3), Part C, Sections 11 and 18

bryantaylor 0:eafc3fd41f75 34 * @par Advertising and Scan Response Payloads
bryantaylor 0:eafc3fd41f75 35 * Advertising data and Scan Response data are organized around a set of
bryantaylor 0:eafc3fd41f75 36 * data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
bryantaylor 0:eafc3fd41f75 37 * Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
bryantaylor 0:eafc3fd41f75 38 *
bryantaylor 0:eafc3fd41f75 39 * @par
bryantaylor 0:eafc3fd41f75 40 * Each AD type has its own standardized assigned number, as defined
bryantaylor 0:eafc3fd41f75 41 * by the Bluetooth SIG:
bryantaylor 0:eafc3fd41f75 42 * https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile.

bryantaylor 0:eafc3fd41f75 44 * @par
bryantaylor 0:eafc3fd41f75 45 * For convenience, all appropriate AD types are encapsulated
bryantaylor 0:eafc3fd41f75 46 * in GapAdvertisingData::DataType.

bryantaylor 0:eafc3fd41f75 48 * @par
bryantaylor 0:eafc3fd41f75 49 * Before the AD Types and their payload (if any) can be inserted into
bryantaylor 0:eafc3fd41f75 50 * the Advertising or Scan Response frames, they need to be formatted as
bryantaylor 0:eafc3fd41f75 51 * follows:
bryantaylor 0:eafc3fd41f75 52 *
bryantaylor 0:eafc3fd41f75 53 * @li @c Record length (1 byte).
bryantaylor 0:eafc3fd41f75 54 * @li @c AD Type (1 byte).

bryantaylor 0:eafc3fd41f75 57 * @par
bryantaylor 0:eafc3fd41f75 58 * This class takes care of properly formatting the payload, performs
bryantaylor 0:eafc3fd41f75 59 * some basic checks on the payload length, and tries to avoid common
bryantaylor 0:eafc3fd41f75 60 * errors like adding an exclusive AD field twice in the Advertising
bryantaylor 0:eafc3fd41f75 61 * or Scan Response payload.
