Description

MIMT mode

1 byte

0x00: MIMT not required

0x01: MIMT required

OOB enable

1 byte

0x00: Out Of Bound authentication not enabled

0x01: Out Of Bound authentication enabled

OOB data

16 bytes

OOB data

Min encryption key

size

1 byte

Minimum size of the encryption key to be used during the pairing

process

Max encryption key

size

1 byte

Maximum size of the encryption key to be used during the pairing

process

Use fixed pin

1 byte

0x00: Use fixed pin during the pairing process

0x01: Do not use fixed pin during the pairing process.

In this case, GAP will generate Evt_Blue_Pin_Code_Request

event to the host.
