Terms and Definitions¶
Bluetooth Low Energy Terms and Acronyms¶
- Application-program interface
- API
- Refers to the function call.
- BLE
- Bluetooth Low Energy
- BR
- Basic Rate
- BR/EDR
- Basic Rate/Enhanced Data Rate
- CCCD
- Client Characteristic Configuration Descriptor
- Coding Indication
- CI
- Bit field in every BLE packet sent on LE Coded PHY that indicates the coding of the PDU (S=2 or S=8).
- Device Address
- A 48-bit value used to identify a device. A device address can be public, random static, or random private.
- Forward Error Correction
- FEC
- Error correction used to improve the sensitivity in the LE Coded PHY.
- GAP
- Generic Access Protocol
- GFSK
- Gaussian Frequency-Shift Keying
- HCI
- Host Control Interface
- Identity Address
- IA
- A Resolvable Private Address that is resolvable 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
- Link Budget
- The link budget is the ratio between the Tx power and the Rx sensitivity level.
- Link Layer
- 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 5.0 referring to the key used for encypted connections.
- Physical layer
- PHY
- The physical layer is the lowest layer of the Bluetooth protocol stack. It configures the physical parameters of the radio transmission and reception. It determines how a bit (and its value) are represented over the air.
- PDU
- Protocol Data Unit
- 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.
- Resolvable Private Address Only
- RPAO
- A required GATT characteristic called “Resolvable Private Address Only” that is used with Network Privacy Mode.
- Simple Non-Volatile storage
- SNV
- An abstraction layer used by the BLE stack for reading and writing to non volatile memory. The GAPBondMgr layer of stack uses SNV to store keys. This region can also be used by the user.
- White List
- WL
- A filter policy in the Controller’s Link Layer that can prevent unwanted link layer events from waking up the host.
Dynamic Multi-protocol Manager Terms and Acronyms¶
- Dynamic Multi-protocol Manager
- DMM
- An arbiter between multiple protocol stacks that are sharing the multi mode RF driver and thus the radio. The DMM aides in scheduling radio operations by way of application provided state information and timing constraints.
