The WCH BLE Analyzer Pro is an inexpensive (~$20) USB Bluetooth LE sniffer and analyzer, useful and a good value for reverse engineering and debugging.

The BLE Analyzer Pro features three CH582F Bluetooth LE RISC-V microcontrollers and a CH334 USB hub, supports Bluetooth Low Energy (BLE) 4.0/4.2/5.0, and connects to the host through its USB-C port.

One downside is that the WCH BLE Analyzer software was only made for Windows 7 to 11.

Xecaz decided to look into it and reverse-engineered the USB protocol to write Linux software using libusb that outputs a standard pcap compatible with popular tools such as Wireshark, or as he puts it: “WinChipHead forgot to ship a Linux driver. We forgot to ask permission.”

The Linux “driver” for the BLE Analyzer Pro tool can be found on GitHub.
