LoRa receiver flowgraph built programmatically via gr-mcp: - osmosdr_source → low_pass_filter → lora_rx → message_debug - XML-RPC server for runtime variable control (samp_rate, center_freq) with introspection enabled - Qt frequency sink for spectrum visualization Docker infrastructure: - gnuradio-lora: gr-lora_sdr OOT module from EPFL (chirp spread spectrum) - gnuradio-lora-runtime: combined runtime with Xvfb + gr-lora_sdr - Compose file, entrypoint, and launch script for LoRa receiver Also includes: - lora_scanner.py: multi-SF LoRa scanner example - lora_infrastructure_test.py: hardware-free pipeline validation (signal_source → throttle → null_sink + xmlrpc variable control) - Integration tests for LoRa scanner flowgraph construction End-to-end pipeline validated: launch_flowgraph → connect_to_container → list_variables → get/set_variable all working through Docker + XML-RPC.
