https://bugzilla.kernel.org/show_bug.cgi?id=202515 --- Comment #7 from Mathias Tillman (master.homer@xxxxxxxxx) --- Thank you for pointing me towards the btmon tool, that does seem to support decoding the LE Extended Connect packets. I've attached two logs, one working and one non-working. In the working one I used a kernel I compiled myself with the use_ext_conn patched out. I started btmon, then restarted the bluetooth service and then tried to connect the mouse - I'm hoping that's enough to catch the hci initialisation? Seems like it from the log anyway. I had a look at the logs, and it seems to disable scanning right before it tries to connect, so I'm not sure that's the problem. However, I'm not familiar with how LE works at all, so I probably shouldn't start speculating. Let me know if you need anything else, and thank you for the help so far. -- You are receiving this mail because: You are the assignee for the bug.
