Lightly modified version of the BLE stack, that doesn't bring up a DFUService by default... as we have our own.

rgrover1 260:ea7f9f14cc15 28 \brief
rgrover1 260:ea7f9f14cc15 29 This class provides several helper functions to generate properly
rgrover1 260:ea7f9f14cc15 30 formatted GAP Advertising and Scan Response data payloads
rgrover1 260:ea7f9f14cc15 31
rgrover1 260:ea7f9f14cc15 32 \note
rgrover1 260:ea7f9f14cc15 33 See Bluetooth Specification 4.0 (Vol. 3), Part C, Section 11 and 18
rgrover1 260:ea7f9f14cc15 34 for further information on Advertising and Scan Response data.
rgrover1 260:ea7f9f14cc15 35
rgrover1 260:ea7f9f14cc15 36 \par Advertising and Scan Response Payloads
rgrover1 260:ea7f9f14cc15 37 Advertising data and Scan Response data are organized around a set of
rgrover1 260:ea7f9f14cc15 38 data types called 'AD types' in Bluetooth 4.0 (see the Bluetooth Core
rgrover1 260:ea7f9f14cc15 39 Specification v4.0, Vol. 3, Part C, Sections 11 and 18).
rgrover1 260:ea7f9f14cc15 40
rgrover1 260:ea7f9f14cc15 41 \par
rgrover1 260:ea7f9f14cc15 42 Each AD type has it's own standardized 'assigned number', as defined
rgrover1 260:ea7f9f14cc15 43 by the Bluetooth SIG:
rgrover1 260:ea7f9f14cc15 44 https://www.bluetooth.org/en-us/specification/assigned-numbers/generic-access-profile
rgrover1 260:ea7f9f14cc15 45
rgrover1 260:ea7f9f14cc15 46 \par
rgrover1 260:ea7f9f14cc15 47 For convenience sake, all appropriate AD types have been encapsulated
rgrover1 260:ea7f9f14cc15 48 into GapAdvertisingData::DataType.
rgrover1 260:ea7f9f14cc15 49
rgrover1 260:ea7f9f14cc15 50 \par
rgrover1 260:ea7f9f14cc15 51 Before the AD Types and their payload (if any) can be inserted into
rgrover1 260:ea7f9f14cc15 52 the Advertising or Scan Response frames, they need to be formatted as
rgrover1 260:ea7f9f14cc15 53 follows:
rgrover1 260:ea7f9f14cc15 54
rgrover1 260:ea7f9f14cc15 55 \li \c Record length (1 byte)
rgrover1 260:ea7f9f14cc15 56 \li \c AD Type (1 byte)
rgrover1 260:ea7f9f14cc15 57 \li \c AD payload (optional, only present if record length > 1)
rgrover1 260:ea7f9f14cc15 58
rgrover1 260:ea7f9f14cc15 59 \par
rgrover1 260:ea7f9f14cc15 60 This class takes care of properly formatting the payload, performs
rgrover1 260:ea7f9f14cc15 61 some basic checks on the payload length, and tries to avoid common
rgrover1 260:ea7f9f14cc15 62 errors like adding an exclusive AD field twice in the Advertising
rgrover1 260:ea7f9f14cc15 63 or Scan Response payload.
