Bluetooth Low Energy Terms and Acronyms¶
- BLE
- Bluetooth Low Energy
- BR
- Basic Rate
- BR/EDR
- Basic Rate/Enhanced Data Rate
- CCCD
- Client Characteristic Configuration Descriptor
- 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

- LE
- Low Energy
- Link Layer
- LL
- A Bluetooth low energy stack layer in on the controller side.
- 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.
