A developer named Xecaz reverse-engineered the USB protocol of the WCH BLE Analyzer Pro, a ~$20 USB Bluetooth LE sniffer that previously only had Windows software. The resulting open-source Linux tool uses libusb and outputs standard pcap files compatible with Wireshark. It captures BLE traffic simultaneously on advertising channels 37/38/39 across all three onboard CH582F RISC-V microcontrollers, enabling decoding of ADV_IND, CONNECT_IND, OUI lookups, and more. An Android app is also in development.
