rgrover1 710:b2e1a2660ec2 29 \brief
rgrover1 710:b2e1a2660ec2 30 This class provides several helper functions to generate properly
rgrover1 710:b2e1a2660ec2 31 formatted GAP Advertising and Scan Response data payloads
rgrover1 710:b2e1a2660ec2 32
rgrover1 710:b2e1a2660ec2 33 \note
rgrover1 710:b2e1a2660ec2 34 See Bluetooth Specification 4.0 (Vol. 3), Part C, Section 11 and 18
rgrover1 710:b2e1a2660ec2 35 for further information on Advertising and Scan Response data.
rgrover1 710:b2e1a2660ec2 36
rgrover1 710:b2e1a2660ec2 37 \par Advertising and Scan Response Payloads
rgrover1 710:b2e1a2660ec2 38 Advertising data and Scan Response data are organized around a set of
rgrover1 710:b2e1a2660ec2 39 data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
rgrover1 710:b2e1a2660ec2 40 Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
rgrover1 710:b2e1a2660ec2 41
rgrover1 710:b2e1a2660ec2 42 \par
rgrover1 710:b2e1a2660ec2 43 Each AD type has it's own standardized 'assigned number', as defined
rgrover1 710:b2e1a2660ec2 44 by the Bluetooth SIG:
rgrover1 710:b2e1a2660ec2 45 https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile
rgrover1 710:b2e1a2660ec2 46
rgrover1 710:b2e1a2660ec2 47 \par
rgrover1 710:b2e1a2660ec2 48 For convenience sake, all appropriate AD types have been encapsulated
rgrover1 710:b2e1a2660ec2 49 into GapAdvertisingData::DataType.
rgrover1 710:b2e1a2660ec2 50
rgrover1 710:b2e1a2660ec2 51 \par
rgrover1 710:b2e1a2660ec2 52 Before the AD Types and their payload (if any) can be inserted into
rgrover1 710:b2e1a2660ec2 53 the Advertising or Scan Response frames, they need to be formatted as
rgrover1 710:b2e1a2660ec2 54 follows:
rgrover1 710:b2e1a2660ec2 55
rgrover1 710:b2e1a2660ec2 56 \li \c Record length (1 byte)
rgrover1 710:b2e1a2660ec2 57 \li \c AD Type (1 byte)
rgrover1 710:b2e1a2660ec2 58 \li \c AD payload (optional, only present if record length > 1)
rgrover1 710:b2e1a2660ec2 59
rgrover1 710:b2e1a2660ec2 60 \par
rgrover1 710:b2e1a2660ec2 61 This class takes care of properly formatting the payload, performs
rgrover1 710:b2e1a2660ec2 62 some basic checks on the payload length, and tries to avoid common
rgrover1 710:b2e1a2660ec2 63 errors like adding an exclusive AD field twice in the Advertising
rgrover1 710:b2e1a2660ec2 64 or Scan Response payload.
