and actually I advise you not to try anything like this, because you
can't measure things this way. The HCI is in between and there are no
rules that maps any of the ACL traffic on HCI to the ACL traffic on the
baseband. Get yourself a protocol analyzer and use its routines for
measurement of the traffic.

I never checked it and as the name suggest it is a test utility.
