While well-developed tools exist for debugging network communication for desktop and web applications, it can be difficult for developers of networked embedded systems to figure out why their network code is failing due to the limited output affordances of embedded devices. This paper presents WiFr\"{o}st, a new approach for debugging these systems using instrumentation that spans from the device itself, to its communication API, to the wireless router and back-end server. WiFr\"{o}st automatically collects this data, displays it in a web-based visualization, and highlights likely issues with an extensible suite of checks based on analysis of recorded execution traces.}, booktitle = {Proceedings of the 31st Annual ACM Symposium on User Interface Software and Technology}, pages = {447–455}, numpages = {9}, keywords = {IDE, embedded systems, debugging, internet of things}, location = {Berlin, Germany}, series = {UIST '18} }
