Terms and Definitions¶
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
- Industrial, Scientific, and Medical
- L2CAP
- Link Logical Control and Adaption Protocol
- 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.
- Resolvable Private Address Only
- RPAO
- A required GATT characteristic called “Resolvable Private Address Only” that is used with Network Privacy Mode.
- White List
- WL
- A filter policy in the Controller’s Link Layer that can prevent unwanted link layer events from waking up the host.

- AP
- Application Processor, the host MCU that implements the user application. Connected to a network processor via a serial interface such as NPI
- UNPI
- Unified Network Processor Interface, a standardized serial transport format that is implemented by TI for the purposes of interfacing to network processor devices like the SNP. UNPI also manages the handshaking required for the serial interface.

- A TI-RTOS Software interrupt.
- TI-RTOS
- Texas Instruments Real Time Operating System
- Zero-Latency Interrupts
- An interrupt that will not be routed through the TI-RTOS kernel’s Hwi dispatcher. For more information, see this wiki article.
Over the Air Download (OAD) Terms and Acronyms¶
- BIM
- Boot Image Manager
- OAD
- Over the Air Download

- The device whose firmware is being upgraded over the air. This is assumed to be a CC26xx device running the TI OAD service.
- OAD Downloader
- The device responsible for accepting an OAD enabled image from the compiler and transferring it over the air to the OAD target.
- SNV
- Simple Non Volatile. 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.
