Reverse-engineered USB protocol in 24hrs; $30 BLE sniffer now works on Linux.

Strengths

•USB protocol reverse-engineering from binaries shows solid low-level skills and clear documentation (CLAUDE.md, RE_PROCESS.md)
•Leverages all three MCUs simultaneously to capture entire BLE advertising spectrum—hardware design awareness
•Dead simple libusb implementation, minimal dependencies, standard pcap output for Wireshark integration

Weaknesses

•Niche audience—only useful if you own this specific $30 device; addressable market is small
•Early-stage: README notes 'working' status but no mention of connection state decryption or link layer reassembly completeness

Post Description

I bought a WCH BLE Analyzer PRO, only to realize it doesn't have Linux support. Using the windows binaries, i reverse engineered their USB implementation, and vibe-coded a capture tool together in less than 24 hours.
