A Mission describes the configuration of zero or more channels including those channels’ transmit and receive ports, codecs, and Rallypoints. Missions are intended to be shared between ICE users as files or QR codes.

Third parties interested in writing software to produce their own, ICE-compatible Mission files can do so by using this section as a guide. A .ice Mission file contains a serialized representation of a single mission object. Object format specification and serialization algorithm is described below.
