HCI Packet Logging of Bluetooth USB Dongles with a TotalPhase Beagle USB Protocol AnalyzerĪfter registration, the TotalPhase’s Beagle Software API is available for Mac/Win/Linux in 32-bit and 64-bit versions. Here’s our experience using the Beagle USB 12 Protocol Analyzer to log Bluetooth communication directly at the USB port. somehow running a Windows VM on Linux and capturing the USB data) or connect a USB Bluetooth Dongle and use a USB Protocol Analyzer. hci_dump (from Linux’ blueZ Bluetooth stack).Īs for Windows, we can either try to log the USB traffic locally (e.g. If you are not using BTstack, but the other side is either macOS or Linux, you can also get an HCI Log via PacketLogger (macOS) resp. By this, the debug output is captured in-line with the Bluetooth packets, which makes them much easier to analyze.

If one side is using BTstack, a good way for this is to just enable HCI Packet Log, convert the console output with the create_packet_log.py tool and then inspect it with Apple’s PacketLogger (macOS only) or Wireshark (any platform).

When a Bluetooth use case doesn’t work as expected, it’s often very helpful to analyze the Bluetooth communication.
