Detailed Description

Vol 3, Part H: 3.5.7 Pairing DHKey Check message.

Vol 3 (Host), Part H (SM): 3 (SMP), 3.5 Pairing Methods

Opcode::PAIRING_DHKEY_CHECK

[uint8_t opcode]
jau::uint128_t dhkey_check_values

Message is used to transmit the 128-bit DHKey Check values (Ea/Eb) generated using f6.
This message is used by both initiator and responder.
This PDU is only used for LE Secure Connections.

Notable: No endian wise conversion shall occur on this data, since the encryption values are interpreted as little-endian or as a byte stream.
