CONFIG_BT_EATT_SEC_LEVEL

Enhanced ATT bearer security level

Type: int

Help

L2CAP server required security level of EATT bearers:
Level 1 (BT_SECURITY_L1) = No encryption or authentication required
Level 2 (BT_SECURITY_L2) = Only encryption required
Level 3 (BT_SECURITY_L3) = Encryption and authentication required
Level 4 (BT_SECURITY_L4) = Secure connection required

Help

L2CAP server required security level of EATT bearers:
Level 1 (BT_SECURITY_L1) = No encryption or authentication required
Level 2 (BT_SECURITY_L2) = Only encryption required
Level 3 (BT_SECURITY_L3) = Encryption and authentication required
Level 4 (BT_SECURITY_L4) = Secure connection required

Direct dependencies

(BT_EATT && BT_CONN && BT_HCI_HOST && BT_RPC_STACK) || (BT_EATT && BT_CONN && BT_HCI_HOST && BT_HCI && BT)

(Includes any dependencies from ifs and menus.)
