LoRa receiver flowgraph built entirely through gr-mcp MCP tools.
Successfully decodes live packets from Heltec V3 beacon at 915MHz,
SF7, BW125k via RTL-SDR.
Signal chain: osmosdr(1MSPS) → LPF(200kHz, dec×2) → lora_rx(500kSPS)
→ message_debug
Key settings for RTL-SDR live reception:
- DC offset auto-correction (mode=2) to remove DC spike at center freq
- IQ balance auto-correction (mode=2)
- signal.pause() fallback for Docker detached mode
- XML-RPC on 0.0.0.0 for Docker host accessibility
