I want to capture Bluetooth packets like PacketLogger.

Some article says Wireshark needs a dongle to capture Bluetooth packets. However, MacBook has own receiver and it enables MacBook to use BlueTooth.

I want to choose the native capture interface, but I cannot find it ( or do not know the correct name)

How can I capture Bluetooth packets by my MacBook?

Environment:

  • MacBook Pro (Retina, 13-inch, Early 2015)
  • macOS Catalina(10.15)
  • Wireshark 3.0.5, installed by Homebrew cask

It doesn't have a name, because it's not an interface that libpcap supports or that a Wireshark extcap module supports.

PacketLogger uses an internal, undocumented mechanism. I looked at the code a long time ago when I was at Apple and had access to the source; I no longer have access, and don't remember what the mechanism was, but it wasn't a documented mechanism, so I couldn't add it to, for example, libpcap.

Use PacketLogger, and then read the PacketLogger trace with Wireshark.

Thank you for your answer! I will capture packets by PaketLogger and see .pklg file by Wireshark.
