- bpod_core.com.verify_serial_discovery(port, expected_message, timeout=1, trigger=None) bool
Check if a device sends an expected discovery message on a serial port.
Opens the specified serial port and waits to receive bytes matching the expected discovery message. Optionally executes a function first, which can be used trigger the device’s discovery routine, e.g., by sending a command.
- Parameters:
port (
str) – The serial port to read from (e.g., ‘/dev/ttyUSB0’ or ‘COM3’).expected_message (
bytes) – The exact byte sequence expected from the device.timeout (
float, default:1) – Maximum time (in seconds) to wait for the discovery message. Defaults to 1 s.trigger (
Callable, optional) – A function to call before reading. Use this to trigger the device’s discovery routine.
- Returns:
True if the device sent the expected message within the timeout period, False otherwise (including if the port cannot be opened).
- Return type:
