Description

The definition of pairing options.

Note

Possible combinations are :

BLE_SMP_OPTION_NONE : No bonding, LE legacy pairing is used.
BLE_SMP_OPTION_BONDING : Bonding requested, LE legacy pairing is used.
BLE_SMP_OPTION_SECURE_CONNECTION : No Bonding. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_SECURE_CONNECTION : Bonding Requested. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing.
BLE_SMP_OPTION_MITM : No bonding, LE legacy pairing is used. MITM protection is required.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_MITM : Bonding requested, LE legacy pairing is used. MITM protection is required.
BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION : No Bonding. MITM protection is required. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION : Bonding Requested. MITM protection is required. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing.
BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : No Bonding. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing. Enable keypress notifications.
BLE_SMP_OPTION_BONDING | BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : Bonding Requested. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing. Enable keypress notifications.
BLE_SMP_OPTION_MITM | BLE_SMP_OPTION_SECURE_CONNECTION | BLE_SMP_OPTION_KEYPRESS : No Bonding. MITM protection is required. If both devices support LE Secure Connections, use LE Secure Connections; 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 is required. If both devices support LE Secure Connections, use LE Secure Connections; otherwise use LE legacy pairing. Enable keypress notifications.
