It used to work for me (a few months, maybe a year ago). Right now when I run it there is no output (even though I granted it Bluetooth Capture permissions and have working RFCOMM communication in my program). Versions: PacketLogger 2024.03.18 (2024.03.18d1) Sequoia 15.4.1 M2 chip
Is PacketLogger working for you on Sequoia?
Oh, it works! I entirely forgot that I did an OS-reinstall and I have to install bluetooth diagnostic profile.
