Convert btsnoop-formatted btmon log

Hi,

I have applied two patches from bluetooth-next...

Bluetooth: Send HCI Set Event Mask Page 2 command only when needed
Bluetooth: btbcm: Read controller features during configuration

...against the official Debian/stretch kernel v4.9.30.

And grabbed a trace-log via 'btmon -w trace.log'.

When doing a...

btmon --read btmom-w_bcm20702_bth-next-fixed.BTSnoop-v1

...I cannot see the lines with "Broadcom Read Controller Features".

What am I doing wrong?

How can I convert that BTsnoop-v1 binary log-file?
Let's say ASCII.

More precisely I wanted to investigate if the list of local-supported
HCI event commands matches/dismatches the list shown from the
firmware.

I hope I could explain it.

Thanks.
