The drone sends BatteryStateChanged from two places with different values: the true figure on buffer 126, corroborated by its own log and tracking a smooth discharge, and a constant 0 on buffer 127 that appears in no log line. Keeping the newest frame meant a healthy aircraft read as flat and preflight refused. Events now carry their buffer and the store keeps the last value per source, so a disagreement is visible instead of silently resolved. get_state reports the sources whenever they differ, rather than handing over a winner. preflight breaks the tie on physical grounds, not preference: an aircraft that is powered and holding a link is not at 0%, so a zero from a live drone is not credible while a non-zero one is. It says the number was contested either way, and a genuine zero from every source still reports zero and still blocks.
mcbebop
An MCP server for the Parrot Bebop 2, so an agent can talk to the drone without anyone writing code for each question.
Parrot abandoned the Bebop line, but the aircraft is still a capable, cheap platform and its protocol is fully described by Parrot's own XML, which this package vendors. Every one of the 264 commands is reachable; nothing is hand-wrapped.
Status: in development. Not flight-tested. See the safety section.
What it talks to
| Interface | Notes |
|---|---|
| ARSDK3 over UDP | commands and telemetry; this package implements the protocol directly |
| ARStream2 | live H.264 video. The Bebop 2 serves no RTSP, despite what older libraries assume |
| FTP | media, flight plans, blackbox logs |
| Telnet | read-only shell, only after the drone's debug mode is enabled |
Safety
Commands are classified by consequence. Observing and configuring are open;
anything that can spin a motor or change the flight envelope refuses until
arm() is called with a reason, and re-locks on a timer and on disconnect.
Landing and Emergency are deliberately never locked, because refusing to
land an airborne aircraft is the more dangerous answer.
connect(target="sim") runs everything against a protocol-accurate simulator,
which is where anything involving motion should be rehearsed.
