Detailed Description

BT Core Spec v5.2: Vol 4, Part E HCI: 7.7.65.5 LE Long Term Key Request event.

HCIPacket:

uint8_t packet_type
HCIEvent:
- uint8_t event_type
- uint8_t packet_len (total = 3 + packet_len)
- HCIMetaEvent
  - uint8_t meta_event_type
  - HCILELTKReqEvent:
    - uint16_t connection_handle (2 octets)
    - uint64_t random_number (8 octets)
    - uint16_t ediv (2 octets)

This event indicates that the peer device being BTRole::Master, attempts to encrypt or re-encrypt the link and is requesting the LTK from the Host.

This event shall only be generated when the local device’s role is BTRole::Slave (responder, adapter in peripheral mode).

Rand and Ediv belong to the local device having role BTRole::Slave (responder).

Rand and Ediv matches the LTK from SMP messaging in SC mode only!

It shall be replied via HCILELTKReplyAckCmd (HCIOpcode::LE_LTK_REPLY_ACK) or HCILELTKReplyRejCmd (HCIOpcode::LE_LTK_REPLY_REJ)
