aid: ble name: BLE description: >- Bluetooth Low Energy (BLE), also known as Bluetooth Smart, is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG). Aimed at IoT and embedded applications, BLE provides reduced power consumption while maintaining similar communication range to classic Bluetooth. The specification is managed by the Bluetooth SIG and covers the full protocol stack including the Generic Attribute Profile (GATT), Generic Access Profile (GAP), and the various service and characteristic specifications used for device interoperability. type: Index image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - BLE - Bluetooth - Embedded - IoT - Protocols - Standards - Wireless url: >- https://raw.githubusercontent.com/api-evangelist/ble/refs/heads/main/apis.yml created: '2025-01-01' modified: '2026-04-21' specificationVersion: '0.19' apis: - aid: ble:bluetooth-core-specification name: Bluetooth Core Specification description: >- The Bluetooth Core Specification defines the complete Bluetooth wireless communication protocol stack including BLE (LE) and Classic Bluetooth. The current stable version is Bluetooth 6.0. The specification covers the Physical Layer, Link Layer, HCI, L2CAP, SM, GAP, and GATT layers, as well as LE Audio, Isochronous Channels, and Direction Finding extensions. humanURL: https://www.bluetooth.com/specifications/specs/core60/ tags: - BLE - Bluetooth - Core Specification - Protocols - Standards properties: - type: Documentation url: https://www.bluetooth.com/specifications/specs/ - type: Specification url: https://www.bluetooth.com/specifications/specs/core60/ - type: JSONSchema url: json-schema/ble-gatt-service-schema.json - type: JSONSchema url: json-schema/ble-advertising-packet-schema.json - type: JSONStructure url: json-structure/ble-gatt-service-structure.json - type: JSONStructure url: json-structure/ble-advertising-packet-structure.json - type: JSONLD url: json-ld/ble-context.jsonld - type: Example url: examples/ble-heart-rate-service-example.json - type: Example url: examples/ble-advertising-packet-example.json - aid: ble:gatt-specification name: GATT and Assigned Numbers description: >- The Generic Attribute Profile (GATT) defines the framework for data transfer between Bluetooth LE devices.
