Adds a new CapturingTransport wrapper in minimateplus.transport that mirrors
every TX/RX byte to two raw .bin files using the same on-wire format as
bridges/ach_mitm.py, so the resulting captures are byte-for-byte compatible
with the existing Blastware MITM captures and load directly in the Analyzer.
A new "Download" tab in seismo_lab.py lets the user connect to a device over
TCP or serial and run connect / list-keys / download-events while the wrapper
saves raw_bw_<ts>.bin (our TX) and raw_s3_<ts>.bin (device TX) into a
seismo_dl_<ts>[_<label>]/ session directory. On completion, the panel hands
both files to the Analyzer and switches tabs, mirroring the UX of the
existing Bridge capture flow.
minimateplus/transport.py:
- Add SocketTransport(TcpTransport) — wraps an already-accepted inbound
socket; connect() is a no-op; everything else inherited from TcpTransport.
Enables the ACH server to reuse all existing protocol/client code without
any changes.
bridges/ach_server.py:
- Minimal inbound ACH server — listens on port 12345, accepts call-home
connections from MiniMate Plus units, runs the full BW protocol:
startup handshake → get_device_info → get_events(full_waveform=True)
- Saves device_info.json + events.json + raw_rx_<ts>.bin + session log
per connection to bridges/captures/ach_inbound_<ts>/
- raw_rx.bin is byte-compatible with existing Analyzer tooling
- Taps transport.read() to capture raw S3 bytes alongside parsed output
- Each connection runs in its own daemon thread
- Clearly distinguishes push vs pull protocol in the startup log

- minimateplus/transport.py: add TcpTransport — stdlib socket-based transport
with same interface as SerialTransport. Overrides read_until_idle() with
idle_gap=1.5s to absorb the modem's 1-second serial data forwarding buffer.
- minimateplus/client.py: make `port` param optional (default "") so
MiniMateClient works cleanly when a pre-built transport is injected.
- minimateplus/__init__.py: export SerialTransport and TcpTransport.
- sfm/server.py: add `host` / `tcp_port` query params to all device endpoints.
New _build_client() helper selects TCP or serial transport automatically.
OSError (connection refused, timeout) now returns HTTP 502.
- docs/instantel_protocol_reference.md: add changelog entry and full §14
(TCP/Modem Transport) documenting confirmed transparent passthrough, no ENQ
on connect, modem forwarding delay, call-up vs ACH modes, and hardware note
deprecating Raven X in favour of RV55/RX55.
Usage: GET /device/info?host=<modem_ip>&tcp_port=12345
