Install better.
Diagnose smarter.
On-board stream reduction.

The live RF Survey mode is now implemented and provides pushed windowed RF quality updates from target BLE sensors.

• Start, status, and stop survey commands.
• Windowed RSSI and packet-consistency scoring.
• Current, best, worst, mean, and final score tracking.
• Live feedback while the user moves the gateway or rotates the antenna.

Status

This now serves as the installed base for the next RF Survey workflow improvements rather than a future roadmap phase.

Build on the RF Survey Mode MVP by allowing users to identify candidate gateway positions, compare the observed RF quality at those positions, and export the result for installation records or support.

• Mark the current survey state with a label.
• Compare marks across one or more target sensors.
• Identify best overall and best per-sensor positions.
• Export the survey result as JSON and a readable summary.

Reasoning

The purpose is to support a more deliberate installation workflow where the user tests multiple physical positions or antenna orientations and then selects the best-performing option using data.

Move detailed BLE gateway diagnostics into a bounded local record-and-query model so the host can access details later when needed.

• Append-only circular diagnostic log.
• Compact common record header plus event-specific payloads.
• Queries by session, address, timestamp, or sequence.
• Flight-recorder bundles for support and correlation.

Reasoning

Diagnostics are currently handled live by the host, which adds transmission and computation overhead. The gateway is always connected to the host, but gateway-side diagnostics can be stored locally and accessed later instead of streamed live in detail.

Add firmware-supported reducers that compute compact metrics from raw BLE/sample streams over defined time windows.

• Reducer registry and common reducer interface.
• List, configure, enable, disable, and status commands.
• First accelerometry reducer over fixed windows.
• Reducer diagnostics captured by the flight recorder.

Reasoning

BLE bandwidth and throughput are always contentious. The hardware can execute dedicated reducers that compute metrics from raw streams, reducing BLE, serial, and host processing load.
