Bluetooth API

The openvela Bluetooth framework provides a complete Bluetooth stack interface, supporting Classic Bluetooth (BR/EDR) and Bluetooth Low Energy (BLE), covering everything from low-level connection management to upper-layer application profiles.

Core Protocols

• GAP (Generic Access Profile) — Device discovery, connection management, pairing and security
• GATT (Generic Attribute Profile) — BLE data attribute read/write and notifications
• Device Management — Remote device pairing, connection, and property queries

BLE Interfaces

• BLE Scanning — BLE device discovery and broadcast data reception
• BLE Advertising — BLE advertising data transmission and management

Audio and Media

• A2DP (Advanced Audio Distribution Profile) — High-quality stereo music streaming
• AVRCP (Audio/Video Remote Control Profile) — Playback control, track change, volume adjustment
• HFP (Hands-Free Profile) — Bluetooth call functionality

Data and Peripherals

• HID (Human Interface Device) — Keyboards, mice, game controllers
• SPP (Serial Port Profile) — Data pass-through
• PAN (Personal Area Network) — Network sharing and Bluetooth networking
