How bear2305/fakesensor works

This repository is an ESP32/Wokwi fake fingerprint sensor that lets a master board use the Adafruit fingerprint protocol without physical sensor hardware. The principal workflow is: the master sends UART commands, the emulator parses and dispatches them, switch inputs supply a simulated finger identity, and command handlers return status or template data while maintaining buffers and stored templates. The README documents enrollment, search, template transfer, password protection, database management, and diagnostics. The sampled source shows dispatch and several handlers; links for omitted internals are not asserted.
