我尝试将我的 Shimmer3 ( http://www.shimmersensing.com/products/shimmer3-imu-sensor ) 与我的 Linux Mint 计算机连接，并尝试使用蓝牙传输数据。为此，我使用 git hub 代码： https ://github.com/seemoo-lab/pyshimmer 。我按照阅读中的说明做了所有事情，但我仍然收到此错误并且无法修复它。这是我的小程序：

import time

from serial import Serial

from pyshimmer import ShimmerBluetooth, DEFAULT_BAUDRATE, DataPacket, EChannelType


def handler(pkt: DataPacket) -> None:
    cur_value = pkt[EChannelType.INTERNAL_ADC_13]
    print(f'Received new data point: {cur_value}')


if __name__ == '__main__':

    serial = Serial('/dev/rfcomm0', DEFAULT_BAUDRATE)
    shim_dev = ShimmerBluetooth(serial)

    shim_dev.initialize()

    dev_name = shim_dev.get_device_name()
    print(f'My name is: {dev_name}')

    shim_dev.add_stream_callback(handler)

    shim_dev.start_streaming()
    time.sleep(5.0)
    shim_dev.stop_streaming()

    shim_dev.shutdown()

这是我的错误/终端输出：
