Add GSS-derived characteristics, array fields, and precise numeric scaling by vkolotov · Pull Request #3 · openhab/bluetooth-gatt-parser

vkolotov · 2026-07-13T11:39:26Z

Summary

Expands the bundled GATT specification set and fills a few gaps in the parser.

Bundled characteristics (191 → 348)

Recovers the Fitness Machine profile and other characteristics from the last published Bluetooth SIG characteristic XML (2017).
Adds 139 characteristics derived from the current GATT Specification Supplement (GSS). The SIG retired the machine-readable characteristic XML repository around 2019; field structure now lives in the GSS YAML, with scaling/unit/presence encoded as a rigid mini-grammar inside prose. Scalars are high fidelity (decode verified); cases the prose cannot express unambiguously carry an inline  marker rather than a fabricated value.

Parser

Variable-length array fields via Field.repeats (0 = repeat to end of data, N = fixed count); the parser emits indexed holders Name[0], Name[1], … (e.g. the RR-Interval list in Heart Rate Measurement).
Registers the GSS float type names medfloat16/medfloat32 (the IEEE-11073 16/32-bit floats).

Numeric conversion

Exact BigDecimal scaling: the decimal exponent is applied via scaleByPowerOfTen and the binary exponent via exact powers of two, so getBigDecimal/getBigInteger no longer inherit the rounding error of Math.pow(10, e).
Simplifies two's-complement int/long deserialization (identical results).
Implements the previously-unsupported IEEE-11073 serialize* and deserializeDouble.

Notes

Target stays at Java 11; no toolchain changes.
README refreshed (GSS provenance, array support; fixed stale links/paths).
Tests: mvn clean test → 127 passing.

Pull request overview

This pull request expands the bundled Bluetooth SIG GATT specification set (including GSS-derived additions) and enhances the parser/number-formatting logic to support repeated (array) fields and more precise numeric conversion/serialization.

Changes:

Add GSS aliases for IEEE-11073 floating-point formats (medfloat16/medfloat32) and implement IEEE-11073 serialize/deserializeDouble support.
Add repeated-field support via Field.repeats and parse-time expansion into indexed field names (Name[0], Name[1], …).
Improve numeric scaling for BigDecimal/BigInteger conversion to avoid Math.pow rounding artifacts; add/update tests and refresh README.

Hey @vkolotov, what a pleasant surprise to see you here!
Many thanks for the huge update of this library. Could you briefly check the few review comments from copilot? Besides this, we should be good to merge.

Should I publish a new version after the merge or do you have any additional changes in the queue for which I should wait?

vkolotov · 2026-07-16T23:28:30Z

Hi @kaikreuzer , yes I'm back and I'm working on something trully exciting now - Direct-BT (based on Tinyb lib) transport binding (direct adapter access, no D-Bus and BlueZ). it shows already some great results, so good that I would recommend deprecating BlueZ binding or at least making the Direct-BT to be enabled by default. It will take a few weeks before I publish a new PR, there are some people who can review it but it would be greate if you could take part in it. Cheers!

PS. I will fix the found issues in this PR and we should be good to publish a new version. Thanks.

@vkolotov Sounds pretty interesting - looking forward to your PR and I'll do my best to help testing it!
