NDEF Record Structure

NDEF Record Structure

The HaLo URL NDEF record contains information about the chip's unique public keys as well as information about the last issued command and last returned response for that command. There is a proprietary interface allowing the user to issue arbitrary commands against the chip using the NDEF layer.

Significant parameter changes occured with verison c5.
