dawnpy-udp

UDP transport extension for dawnpy. Provides the dawnpy-udp CLI for talking to a Dawn device over UDP/IP.

Installation

Requires the core dawnpy package to be installed first:

pip install -e tools/dawnpy-udp

Dependencies (installed automatically): dawnpy, click >= 8.1. The Python standard library handles socket I/O, so no extra transport package is required.

Command

dawnpy-udp 192.0.2.10
dawnpy-udp 192.0.2.10 --port 50000
dawnpy-udp 192.0.2.10 --descriptor descriptor.yaml
dawnpy-udp --help

The command requires the target host address and opens an interactive UDP console. By default it uses the Dawn simple protocol discovery commands (CMD_LIST_IOS and CMD_GET_INFO) to query the device at runtime. Passing --descriptor / -d uses the YAML descriptor as the IO list instead, then reads those ObjectIDs from the device.

Common options:

--descriptor / -d: optional descriptor.yaml path or configuration directory. Use this when the host should inspect the full descriptor-defined device state instead of relying on runtime CMD_LIST_IOS discovery.
--port / -p: UDP port. Defaults to 50000.
--debug / --no-debug: enable verbose protocol logging.

Console

The interactive console shares the command set documented in Interactive Console Commands (see dawnpy-serial).
