this aligns port 10 expectations to reality for smart label and tag xl and therefore loros.

Summary by CodeRabbit

  • Bug Fixes
    • Corrected GNSS altitude decoding for SmartLabel and TagXL devices.
    • Updated port 10 payload parsing to report movement status consistently.
    • Corrected battery value decoding and voltage handling.
    • Updated decoded payload output to reflect the revised movement and altitude values.

📝 Walkthrough

Walkthrough

Port 10 GNSS decoding now exposes movement as a boolean, interprets altitude in decimeters, and updates battery typing. SmartLabel and TagXL decoder configurations, payload structures, documentation, fixtures, feature checks, and JSON assertions reflect the new format.

Changes

Port 10 GNSS decoding

Layer / File(s) Summary
SmartLabel Port 10 decoding
pkg/decoder/smartlabel/v1/port10.go, pkg/decoder/smartlabel/v1/decoder.go, pkg/decoder/smartlabel/v1/decoder_test.go
SmartLabel replaces Status with Moving, decodes altitude by dividing by 10, retains battery scaling through the renamed transform, changes Battery to float32, and updates decode and marshal tests.
TagXL Port 10 decoding
pkg/decoder/tagxl/v1/port10.go, pkg/decoder/tagxl/v1/decoder.go, pkg/decoder/tagxl/v1/decoder_test.go, pkg/decoder/tagxl/v1/port10_test.go
TagXL replaces Status with movement decoding, changes altitude scaling from 100 to 10, renames the battery transform, and updates payload, feature, movement, and marshal tests.

Priority: ⬇️ Low — Defer this decoder change because it is limited to Smart Label and Tag XL port 10 movement and altitude decoding.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 42eb0

This change corrects GNSS altitude scaling and exposes movement state, but SmartLabel consumers using feature detection will not see movement support and the moving=true decode path lacks coverage. Resolve these issues before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a positive movement-bit test.

The four SmartLabel Port 10 decode fixtures use a first byte of 0x00. These assertions only verify Moving == false. A decoder that always returns false would pass them. Add a fixture with bit 0 set, such as a payload beginning with 0x01, and assert payload.Moving == true.

Advertise FeatureMoving for SmartLabel port 10.

Because port 10 now decodes Moving, add decoder.FeatureMoving to the SmartLabel port 10 feature list. Decode forwards config.Features to decoder.NewDecodedUplink; without this flag, decodedPayload.Is(decoder.FeatureMoving) remains false. TagXL already includes this feature in pkg/decoder/tagxl/v1/decoder.go:92.

Proposed fix
-			Features:   []decoder.Feature{decoder.FeatureGNSS, decoder.FeatureTimestamp, decoder.FeatureBattery},
+			Features:   []decoder.Feature{decoder.FeatureGNSS, decoder.FeatureTimestamp, decoder.FeatureBattery, decoder.FeatureMoving},
