jksoft 0:76dfa9657d9d 26 \brief
jksoft 0:76dfa9657d9d 27 This class provides several helper functions to generate properly
jksoft 0:76dfa9657d9d 28 formatted GAP Advertising and Scan Response data payloads
jksoft 0:76dfa9657d9d 29
jksoft 0:76dfa9657d9d 30 \note
jksoft 0:76dfa9657d9d 31 See Bluetooth Specification 4.0 (Vol. 3), Part C, Section 11 and 18
jksoft 0:76dfa9657d9d 32 for further information on Advertising and Scan Response data.
jksoft 0:76dfa9657d9d 33
jksoft 0:76dfa9657d9d 34 \par Advertising and Scan Response Payloads
jksoft 0:76dfa9657d9d 35 Advertising data and Scan Response data are organized around a set of
jksoft 0:76dfa9657d9d 36 data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
jksoft 0:76dfa9657d9d 37 Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
jksoft 0:76dfa9657d9d 38
jksoft 0:76dfa9657d9d 39 \par
jksoft 0:76dfa9657d9d 40 Each AD type has it's own standardized 'assigned number', as defined
jksoft 0:76dfa9657d9d 41 by the Bluetooth SIG:
jksoft 0:76dfa9657d9d 42 https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile
jksoft 0:76dfa9657d9d 43
jksoft 0:76dfa9657d9d 44 \par
jksoft 0:76dfa9657d9d 45 For convenience sake, all appropriate AD types have been encapsulated
jksoft 0:76dfa9657d9d 46 into GapAdvertisingData::DataType.
jksoft 0:76dfa9657d9d 47
jksoft 0:76dfa9657d9d 48 \par
jksoft 0:76dfa9657d9d 49 Before the AD Types and their payload (if any) can be inserted into
jksoft 0:76dfa9657d9d 50 the Advertising or Scan Response frames, they need to be formatted as
jksoft 0:76dfa9657d9d 51 follows:
jksoft 0:76dfa9657d9d 52
jksoft 0:76dfa9657d9d 53 \li \c Record length (1 byte)
jksoft 0:76dfa9657d9d 54 \li \c AD Type (1 byte)
jksoft 0:76dfa9657d9d 55 \li \c AD payload (optional, only present if record length > 1)
jksoft 0:76dfa9657d9d 56
jksoft 0:76dfa9657d9d 57 \par
jksoft 0:76dfa9657d9d 58 This class takes care of properly formatting the payload, performs
jksoft 0:76dfa9657d9d 59 some basic checks on the payload length, and tries to avoid common
jksoft 0:76dfa9657d9d 60 errors like adding an exclusive AD field twice in the Advertising
jksoft 0:76dfa9657d9d 61 or Scan Response payload.
jksoft 0:76dfa9657d9d 62
