SMP Pairing Request Vol 3, Part H (SM): 3.5.1

Initiator starts the Pairing Feature Exchange by sending a Pairing Request command to the responding device.

The rules for handing a collision between a pairing procedure on the LE transport and a pairing procedure on the BR/EDR transport are defined in Vol 3, Part C (GAP): 14.2 BRD/EDR/LE security aspects - Collision Handling.

SMP Pairing Response Vol 3, Part H (SM): 3.5.2

Command is used by the responding device to complete the Pairing Feature Exchange after it has received a Pairing Request command from the initiating device, if the responding device allows pairing.

If a Pairing Request is received over the BR/EDR transport when either cross-transport key derivation/generation is not supported or the BR/EDR transport is not encrypted using a Link Key generated using P256, a Pairing Failed shall be sent with the error code SMPPairFailedMsg::ReasonCode::CROSSXPORT_KEY_DERIGEN_NOT_ALLOWED (Cross-Transport Key Derivation/Generation Not Allowed).

The rules for handing a collision between a pairing procedure on the LE transport and a pairing procedure on the BR/EDR transport are defined in Vol 3, Part C (GAP): 14.2 BRD/EDR/LE security aspects - Collision Handling.
