--- Begin Message --- Thanks for the feedback Guy. I revised the wording based on your suggestion, while also noting there is a four octet access address in the LE packet before the coding indicator. See the updated version here since the GitHack version rendered with a suitable Content-Type is sl

--- Begin Message --- Hmm. Chris Kilgour (whiterocker) originally created the spec, and the version on tcpdump.org was just a backup copy. Now, Chris has said that he is no longer active in the Bluetooth LE sniffing space, and he doesn’t want to be in charge of the spec any more. Perhaps the sp
