# WCH BLE Analyzer Pro: reconstructing its USB capture protocol for Linux

> The WCH BLE Analyzer Pro project reconstructs the USB capture protocol of a three-channel BLE sniffer and implements a Linux libusb driver. It sends monitor commands to the device's CH582F controllers, decodes returned frames and writes BLE link-layer packets to pcap for Wireshark. Research notes describe USB captures and analysis of bundled decoder scripts.
