Sensor Functions

dev.io.sensors - wire path i\s - generated from fwMenuSensors.

enable_motion_stream

Stream Motion. Streams accelerometer and gyroscope data to the host at the given rate. 0 stops the stream.

Wire command: i\s\m

Arg	Wire type
stream_rate_ms	decS32

Returns: none (Ok/Err only)

dev.io.sensors.enable_motion_stream(stream_rate_ms: int) -> Result

ow_status ow_io_sensors_enable_motion_stream(ow_device* dev, int32_t stream_rate_ms);

dev.io().sensors().enable_motion_stream(stream_rate_ms: i32) -> Result<(), OwError>

The C and Rust signatures above are also the WASM guest signatures - the device API surface is identical; only the transport differs (ow_open_wasm(&dev) in C, OneWili::open() in Rust).

dev.io.sensors.enable_motion_stream(stream_rate_ms)   # check dev.ok

enable_field_stream

Stream Field. Streams magnetometer data to the host at the given rate. 0 stops the stream.

Wire command: i\s\f

Arg	Wire type
stream_rate_ms	decS32

Returns: none (Ok/Err only)

dev.io.sensors.enable_field_stream(stream_rate_ms: int) -> Result

ow_status ow_io_sensors_enable_field_stream(ow_device* dev, int32_t stream_rate_ms);

dev.io().sensors().enable_field_stream(stream_rate_ms: i32) -> Result<(), OwError>

The C and Rust signatures above are also the WASM guest signatures - the device API surface is identical; only the transport differs (ow_open_wasm(&dev) in C, OneWili::open() in Rust).

dev.io.sensors.enable_field_stream(stream_rate_ms)   # check dev.ok

enable_env_stream

Stream Env. Streams temperature, humidity and ambient light to the host. This stream is change-driven: the rate is a heartbeat floor, so samples can arrive faster when readings move. 0 stops the stream.

Wire command: i\s\e

Arg	Wire type
stream_rate_ms	decS32

Returns: none (Ok/Err only)

dev.io.sensors.enable_env_stream(stream_rate_ms: int) -> Result

ow_status ow_io_sensors_enable_env_stream(ow_device* dev, int32_t stream_rate_ms);

dev.io().sensors().enable_env_stream(stream_rate_ms: i32) -> Result<(), OwError>

The C and Rust signatures above are also the WASM guest signatures - the device API surface is identical; only the transport differs (ow_open_wasm(&dev) in C, OneWili::open() in Rust).

dev.io.sensors.enable_env_stream(stream_rate_ms)   # check dev.ok

enable_orientation_stream

Stream Orientation. Streams fused roll, pitch, yaw and heading to the host at the given rate. 0 stops the stream.

Wire command: i\s\r

Arg	Wire type
stream_rate_ms	decS32

Returns: none (Ok/Err only)

dev.io.sensors.enable_orientation_stream(stream_rate_ms: int) -> Result

ow_status ow_io_sensors_enable_orientation_stream(ow_device* dev, int32_t stream_rate_ms);

dev.io().sensors().enable_orientation_stream(stream_rate_ms: i32) -> Result<(), OwError>

The C and Rust signatures above are also the WASM guest signatures - the device API surface is identical; only the transport differs (ow_open_wasm(&dev) in C, OneWili::open() in Rust).

dev.io.sensors.enable_orientation_stream(stream_rate_ms)   # check dev.ok

get_sensors

Get Sensors. Prints the most recent sample from each of the four sensor groups.

Wire command: i\s\g

Returns: none (Ok/Err only)

dev.io.sensors.get_sensors() -> Result

ow_status ow_io_sensors_get_sensors(ow_device* dev);

dev.io().sensors().get_sensors() -> Result<(), OwError>

The C and Rust signatures above are also the WASM guest signatures - the device API surface is identical; only the transport differs (ow_open_wasm(&dev) in C, OneWili::open() in Rust).

dev.io.sensors.get_sensors()   # check dev.ok

Events

Spontaneous frames this menu emits (not command responses). Text events arrive as [*<id> ...] frames (Python: Transport.events; C: ow_poll_text_event; Rust: poll_event -> Event::Text); binary events use the binary API below. The on-device rthon binding does not receive event streams in v1.
