The distribution and import package remain named sds200; the user-facing project and executable are named sdsctl. New code should use SDSScanner.

USB

from sds200 import SDSScanner

with SDSScanner.auto(model="SDS150") as radio:
    print(radio.get_model())
    print(radio.get_firmware())
    print(radio.get_volume())
    print(radio.get_squelch())

SDS200 Ethernet

from sds200 import SDSScanner

with SDSScanner.network("192.168.1.25") as radio:
    info = radio.get_scanner_info()
    print(info.system)
    print(info.department)
    print(info.channel)
    print(info.frequency)

Continuous state updates

from sds200 import SDSScanner

with SDSScanner.network("192.168.1.25") as radio:
    radio.on_state_change(
        lambda change: print(change.fields, change.current.channel)
    )

    with radio.scanner_info_push(interval_ms=500):
        radio.wait()

Reconnect and health

from sds200 import ReconnectPolicy, SDSScanner

policy = ReconnectPolicy(
    initial_delay=1.0,
    multiplier=2.0,
    max_delay=30.0,
    max_attempts=8,
)

with SDSScanner.network(
    "192.168.1.25",
    reconnect_policy=policy,
) as radio:
    print(radio.health_check().as_dict())
    print(radio.health_summary().as_dict())

LAN discovery

from sds200 import discover_network_scanners

for scanner in discover_network_scanners(["192.168.1.0/24"]):
    print(scanner.endpoint, scanner.model, scanner.latency_ms)

Only probe networks you own or are authorized to scan. Close scanners and bounded push contexts deterministically, as shown by the context managers. Consult the repository source, type annotations, and transport guide for advanced integration work.
