BLE

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.

BLE publishes 3 APIs on the APIs.io network. Tagged areas include BLE, Bluetooth, Embedded, IoT, and Protocols.

The BLE catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

BLE’s developer surface includes documentation, training material, and 9 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ble: open an issue to ask a question, or submit a pull request to add artifacts.
