Question

我正在尝试阅读ANT+ garmin usb中的数据并按照本教程https://www.johannesbader.ch/2014/06/track-your-heartrate-on-raspberry-pi-with-ant/

但是我收到了这个错误，

starting node
Traceback (most recent call last):
  File "garmin_ant_demo.py", line 71, in <module>
    sys.exit(0)
  File "garmin_ant_demo.py", line 39, in __exit__
    self.stop()
  File "garmin_ant_demo.py", line 33, in stop
    self.antnode.stop()
  File "build/bdist.linux-x86_64/egg/ant/core/node.py", line 167, in stop
ant.core.exceptions.NodeError: Could not stop ANT node (not started).

运行时

python garmin_ant_demo.py

在我使用上述方法失败后，我从git克隆了以下repo，

https://github.com/Loghorn/ant-plus

并尝试运行给定的示例程序（https://github.com/Loghorn/ant-plus/blob/master/sample/sample.js），但我一直收到以下错误，

    this.device.__claimInterface(this.id)
                ^

我尝试研究错误Error: LIBUSB_ERROR_BUSY，但根本没有运气，事实上有人有同样的问题How to solve LIBUSB_ERROR_BUSY on Raspberry Pi (Debian) running Node.js但没有得到任何回复。

从ANT + garmin USB读取数据
