Hi, I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments. This document is for the Standards Track. This document defines how IPv6 is transported over Low Energi Bluetooth leveraging 6LoWPAN techniques for 802.15.4. I have no real feedback. The document is well written and makes sense to me. The compression details are a bit outside of my experience so didn’t get into all the details there. There are no real nits (one single referenced draft has a newer version) and my only semantical small change would be: - 3.2.4 first paragraph, remove “in this document”. Header compression as defined … … is REQUIRED as the basis … … Those two first sentences are a little repetitive which adds to it - 3.3, should this just be moved up under 3.2.1 or something? Its only referenced there unless I’m missing something and doesn’t need the context of what comes after. /nco
