OptoGrid

class OptoGrid(sessions_directory: str = '', filename: str = '', device_name: str = 'OptoGrid 1', command_timeout: float = 5.0, scan_timeout: float = 4.0, device_log: bool = False, save_accel_gyro: bool = True, save_orientation: bool = True, save_magnetometer: bool = False, imu_logging: bool = True, sham: bool = False)

Bases: object

Synchronous, thread-safe BLE driver for the OptoGrid, with optional IMU logging. BLE work happens on a private background thread; public methods block the calling thread for the BLE round-trip but never block the loop.

Methods

Attributes

imu_raw_history: deque

start() → None

stop() → None

property is_connected: bool

property is_connecting: bool

property address: str | None

status() → str

Human-readable connection status, e.g. for a GUI label.

connect(identifier: str | None = None, timeout: float = 10.0) → bool

connect_async(identifier: str | None = None, timeout: float = 10.0) → None

Connect in a background thread. Returns immediately. Check is_connected / is_connecting for status.

disconnect() → bool

scan() → list[str]

trigger() → bool

program(settings: OptoSetting) → bool

start_imu_logging() → str | None

Enable the IMU on the device and start logging to a CSV file. Returns the file path, or None on failure.

sync(value: int = 1) → bool

Manually mark a sync value in the IMU stream, independent of trigger().

Useful to mark task events (e.g. trial onset) in the IMU log. If IMU logging is not active, returns False without doing anything.

stop_imu_logging() → str | None

Disable the IMU on the device and close the CSV file. Returns the file path that was written.

property imu_logging: bool

toggle_status_led(on: bool) → bool

toggle_sham_led(on: bool) → bool

read_battery_mv() → int | None

read_last_stim_ms() → int | None

read_uled_check() → int | None

read_device_id() → str | None

read_params() → dict[str, str] | None

Read all opto parameters and device info from the connected device.
