Trying to calculate distance but get "AttributeError: module 'acconeer.exptool.a121' has no attribute 'DetectorConfig'

[yalatoom]

I tried to use this code based on your example to calculate distance:

import acconeer.exptool as et
from acconeer.exptool import a121
from acconeer.exptool.a121.algo.distance import Detector, DetectorConfig, ThresholdMethod

SENSOR_ID = 1

def main():
    # Specify the connection method and device manually
    serial_port = "/dev/ttyUSB1"  # Example: specify the serial port for USB connection

    # Open the connection to the sensor
    client = a121.Client.open(serial_port=serial_port)

    # Other parts of the script remain the same
    detector_config = a121.DetectorConfig(
        start_m=0.0,
        end_m=2.0,
        max_profile=a121.Profile.PROFILE_3,
        max_step_length=12,
        threshold_method=a121.ThresholdMethod.RECORDED,
    )
    detector = a121.Detector(client=client, sensor_ids=[SENSOR_ID], detector_config=detector_config)

    detector.calibrate_detector()

    detector.start()

    interrupt_handler = et.utils.ExampleInterruptHandler()
    print("Press Ctrl-C to end session")

    while not interrupt_handler.got_signal:
        detector_result = detector.get_next()
        try:
            if detector_result is not None:
                for distance in detector_result[SENSOR_ID].distances:
                    print("Distance:", distance)
        except et.PGProccessDiedException:
            break

    detector.stop()

    print("Disconnecting...")
    client.close()

if __name__ == "__main__":
    main()

but get this error:

AttributeError: module 'acconeer.exptool.a121' has no attribute 'DetectorConfig'

I am using Raspberry Pi and connected "SparkFun Qwiic Pulsed Coherent Radar Sensor - Acconeer XM125" with USB port to my Raspberry Pi.

Line 15 should say: detector_config = DetectorConfig( and not detector_config = a121.DetectorConfig(

Thank you. It solved that error but received another error:

Try lowering the baudrate to get a more stable connection:

    # Open the connection to the sensor
    client = a121.Client.open(serial_port=serial_port, override_baudrate=115200)

Thank you. That solve my issue and it works now.
