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
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.

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.

Swi
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

OAD Target

The device whose firmware is being upgraded over the air. This is assumed to be a CC26xx device running the TI OAD service.

OAD Target App also refers to the Image A project for on-chip OAD applications

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.
