Device Address
A 48-bit value used to identify a device. A device address can be public, random static, or random private.
GAP
Generic Access Protocol
GFSK
Gaussian Frequency-Shift Keying
HCI
Host Control Interface
Identity Address
IA
A Resolvable Private Address that is resolveable with an Identity Resolving Key yields an Identity Address.
Identity Resolving Key
IRK
A key exchanged during Phase 3 of the bonding process. A Resolving List contains a local and a peer Identity Resolving Key as well as an Identity Address.
ISM
Industrial, Scientific, and Medical
L2CAP
Link Logical Control and Adaption Protocol
LE
Low Energy
LL
A Bluetooth low energy stack layer in on the controller side.
LTK
Long Term Key
A term defined by the Bluetooth Core Specification Version 4.2 referring to the key used for encypted connections.
PHY
Physical Layer
Resolving List
RL
A Link Layer maintained table of one or more entries of a local and peer Identity Resolving Key associated to an Identity Address.
Resolvable Private Address
RPA
A resolvable address is one that can be resolved given that the device has an Identity Resolving Key. By resolving a Resolvable Private Address one can determine its Identity Address.
White List
WL
A filter policy in the Controller’s Link Layer that can prevent unwanted link layer events from waking up the host.
Long Term Key
LTK
A symmetric 128-bit key that is used to encrypt an encrypted BLE link.
