Vol 3, Part H: 3.5.3 Pairing Confirm message.
Vol 3 (Host), Part H (SM): 3 (SMP), 3.5 Pairing Methods
[uint8_t opcode] jau::uint128_t confirm_value
Used following a successful Pairing Feature Exchange to start STK Generation for LE legacy pairing and LTK Generation for LE Secure Connections pairing.
Command is used by both devices to send the confirm value to the peer device,
see Vol 3, Part H, 2.3.5.5 SM - Pairing algo - LE legacy pairing phase 2 and
and Vol 3, Part H, 2.3.5.6 SM - Pairing algo - LE Secure Connections pairing phase 2.
The initiating device starts key generation by sending the Pairing Confirm command to the responding device.
If the initiating device wants to abort pairing it can transmit a Pairing Failed command instead.
The responding device sends the Pairing Confirm command after it has received a Pairing Confirm command from the initiating device.
Notable: No endian wise conversion shall occur on this data, since the encryption values are interpreted as little-endian or as a byte stream.

inlineconstexprnoexcept |
Returns the 128-bit Confirm value (16 octets)
In LE legacy pairing, the initiating device sends Mconfirm and the responding device sends Sconfirm as defined in Vol 3, Part H, 2.3.5.5 SM - Pairing algo - LE legacy pairing phase 2
In LE Secure Connections, Ca and Cb are defined in Vol 3, Part H, Section 2.2.6 SM - Crypto Toolbox - LE Secure Connections confirm value generation function f4.
See Vol 3, Part H, 2.3.5.6 SM - Pairing algo - LE Secure Connections pairing phase 2.
