Layrz Link Protocol

Changelog

3.1.2

• Fixed Dart TCP client <AuPacket> handling using return instead of continue, which caused <AsPacket> to be missed when both arrived in the same TCP chunk
• Added Dart TCP client IPv6 preference: hostname resolution now picks an AAAA record when available, falling back to A

3.1.1

• Fixed Go BleAdvertisement.Latitude, Longitude, and Altitude fields changed from float64 to *float64 so devices without GPS fix correctly report absent coordinates as nil instead of 0.0
• Fixed Go <Pb> packet parser to return an error (rather than silently zero-ing) when coordinate fields are present but non-numeric
• Fixed Go <Pb> parser to normalize MAC addresses to uppercase colon-separated format (AA:BB:CC:DD:EE:FF) after CRC validation

3.1.0

• Added full C++ implementation (cpp/) with CMake C++17 build, covering all packet types (Pa, Pb, Pc, Pd, Pi, Pm, Pr, Ps, Ab, Ac, Ao, Ar, As, Au, Ts, Te, Im), CRC-16/X-25, BLE advertisement codec, extras parser, and HTTP/TCP transports
• Added Go v3 implementation with full protocol parity against the Python source of truth
• Fixed Dart parity issues against Python wire format (field order, CRC scope, <Te> and <Ts> packets)
• Migrated Python type checker from mypy to ty; bumped requires-python to >=3.13
