- Rewrite README with v2 features (OpenClaw, M5 Echo, Opus, pluggable backends),
fold ARCHITECTURE.md and PIPELINE.md content inline
- Remove dev-only test scripts (streaming TTS, UDP recv, qwen3 bench, etc.)
- Remove redundant m5_echo/flash.sh and terminal.py (root scripts handle both)
- Consolidate credentials to .template naming, remove .example
- Embed parakeet-mlx ASR server as optional dependency (pipeline/services/asr_server.py)
- Default LLM to Claude Haiku 4.5 via OpenRouter, local example uses Gemma 4 E4B
- Update pyproject.toml with metadata, bump to 2.0.0
- Clean up .gitignore
- Add managed conversation backend for OpenClaw (x-openclaw-message-channel
header, user field for device identity)
- Replace aggressive interrupt logic with VAD-aware check: only interrupt
on actual speech, not background noise/trailing packets
- Fix 0xDD timeout units (was milliseconds, now seconds) and keep callActive
alive with 30s hold during LLM+TTS processing
- Set callActive on boot for VOX mode so device accepts audio without tap
- Mic timeout no longer kills callActive — only double-tap ends the call
- LED feedback: scale to configured led_power, let device handle fade-down
- Add greeting toggle, TTS/SEND logging, pyserial dep, setuptools config
PTT devices (--device name=ip:ptt): skip VAD, buffer audio until packets
stop, skip LED commands, interrupt in-flight responses on new audio.
Auto-detected from multicast "PTT" announcement.
HTTP control server on :3002 for runtime device management:
POST/GET/DELETE /devices
Firmware: replace per-chunk DC offset with IIR filter to eliminate
zipper noise at chunk boundaries (m5_echo + onjuino).
Protocol: TCP timeouts use actual timeout param, failures are silent
for non-critical commands (LED blink).
Pipeline: labeled error logging (ASR/LLM/TTS), env var resolution
warning, Gemini OpenAI-compatible endpoint support.
Test scripts: rewritten to use pipeline modules, delete redundant
test_opus_tts.py, add pyproject.toml (replaces requirements.txt).
