The transport is threaded and the session puts an async face on it, so
pings and acks are answered whether or not anyone is awaiting a
coroutine. Telemetry is stored per key with a timestamp, because a drone
that has stopped reporting otherwise reads identically to one repeating
itself.
Encoding goes through protocol/codec lazily, so this lands without
waiting for that stream; the sim carries a small encoder of its own for
the events it sends, which also keeps it from agreeing with the client
about a shared mistake.
Ported from bebop-2's sim.py, retargeted at the vendored XML and with
the identity burst now sent per controller attach rather than once per
process.
protocol/types.py and arsdk/types.py are the interfaces the parallel streams
build against: command/arg/enum/expectation specs and the safety tiers on one
side, frame encoding and the buffer conventions on the other.
Logging goes to stderr throughout, since stdout carries JSON-RPC. That is also
why this package will speak ARSDK itself rather than through pyparrot, which
prints from its receive thread.
Bebop-era snapshot of common.xml and ardrone3.xml (BSD-3-Clause, Parrot SA),
with pyparrot's <myclass> rename reverted to Parrot's <class>. Provenance and
the comparison against upstream master are in arsdk-xml/PROVENANCE.md.
