WiFröst: Bridging the Information Gap for Debugging of Networked Embedded Systems
summary
WiFröst instruments the microcontroller, local router and server and aggregates those streams into a web IDE timeline so networked bugs become visible. It uses a modified WiFi library that tags HTTP transactions, mitmproxy on Raspberry Pi for router logging and a logic analyser synchronized traces approach to correlate microsecond device events with slower network events. The system supports HTTP/HTTPS, flags wrong WiFi passwords, DNS resolution failures, bad API keys and JSON error fields via automated extensible checks, and the demo shows the visualization and checks successfully find and explain faults.
