What is blue-dragon?

Blue Dragon (github.com/alphafox02/blue-dragon) is a Rust-powered passive sniffer for ultra wideband BLE 5 and Classic Bluetooth using SDRs like USRP B210, HackRF, or bladeRF. It grabs up to 40 BLE channels at once—no hopping, no misses—decoding LE 1M/2M/Coded PHYs plus BR packets, then spits out Wireshark PCAPs, ZMQ streams with GPS tags, or a live web dashboard. Think full 2.4GHz BLE band in one sweep for drive tests or site surveys.

Why is it gaining traction?

Single-channel sniffers like Ubertooth drop packets during hops; Blue Dragon's wideband channelizer catches everything simultaneously, including rare LE Coded long-range ads. ZMQ multi-sensor fusion, CurveZMQ encryption, and Wireshark extcap integration make it deployable for real-world BLE/blue tracking, outpacing narrowband tools.

Who should use this?

Bluetooth security researchers mapping IoT trackers or beacons in warehouses; pentesters auditing Classic BT in cafes/hotels; reverse engineers debugging BLE 5 connections during vehicle surveys with GPS-tagged captures.

Verdict

Solid niche tool at 12 stars and 1.0% credibility—mature docs, easy DragonOS builds, tested to 95% CRC rates. Grab it if wideband BLE sniffing fits; skip for basic debugging until more validation.
