Description

Defines pairing options for Bluetooth Low Energy Security Manager Protocol (SMP).

Note

Possible combinations are :

BLE_SMP_OPTION_NONE : No bonding, use LE legacy pairing.
BLE_SMP_OPTION_BONDING : Bonding requested, use LE legacy pairing.
BLE_SMP_OPTION_SECURE_CONNECTION : No bonding, prefer LE Secure Connections if supported, otherwise use LE legacy pairing.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_SECURE_CONNECTION : Bonding requested, prefer LE Secure Connections if supported, otherwise use LE legacy pairing.
BLE_SMP_OPTION_MITM : Man-In-The-Middle (MITM) protection required, no bonding, use LE legacy pairing.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_MITM : Bonding requested, MITM protection required, use LE legacy pairing.
BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION : MITM protection required, no bonding, prefer LE Secure Connections if supported, otherwise use LE legacy pairing.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION : Bonding requested, MITM protection required, prefer LE Secure Connections if supported, otherwise use LE legacy pairing.
BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : No bonding, prefer LE Secure Connections if supported, otherwise use LE legacy pairing, enable keypress notifications.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : Bonding requested, prefer LE Secure Connections if supported, otherwise use LE legacy pairing, enable keypress notifications.
BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : MITM protection required, no bonding, prefer LE Secure Connections if supported, otherwise use LE legacy pairing, enable keypress notifications.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : Bonding requested, MITM protection required, prefer LE Secure Connections if supported, otherwise use LE legacy pairing, enable keypress notifications.
