Hi Mohit,
Thanks for sparing time to review the draft and showing interest.

Indeed the draft considers CoAP over UDP. That is why we have put only RFC 7252 in the reference. But, we should explicitly mention this in the draft. Thanks for pointing this out.

 Yes we do have. As I mentioned in a previous communication, we have an accepted paper in Globecom workshop on UAV and is due to be presented this December. If we get a chance to present the draft in a physical meeting, we can discuss more with visuals of the experiments and the results under different connection environments.

Thank you.
