我有一个micro：bit（v1.3 B），我正在尝试在MacBook（macOS Monterey）上使用Python bitio library。我一直在学习入门部分，已经到了“建立连接”部分。
我已经通过上传文件将bitio.hex文件“闪现”到micro：bit，它成功地显示了bitio标志，就像here所示的那样。
当我运行python3 counter.py时，它给出了以下错误：

microbit.repl.repl.REPLException: Timeout trying to receive [
raw EPL; CTRL-B to exit
>]

完整回溯：

Traceback (most recent call last):
  File "/Users/User/Downloads/bitio-master/src/counter.py", line 3, in <module>
    import microbit
  File "/Users/User/Downloads/bitio-master/src/microbit/__init__.py", line 130, in <module>
    repl.to_raw()
  File "/Users/User/Downloads/bitio-master/src/microbit/repl/repl.py", line 109, in to_raw
    self.wait_repl_response()
  File "/Users/User/Downloads/bitio-master/src/microbit/repl/repl.py", line 143, in wait_repl_response
    self.receive("\r\nraw REPL; CTRL-B to exit\r\n>", timeout=2)
  File "/Users/User/Downloads/bitio-master/src/microbit/repl/repl.py", line 82, in receive
    raise REPLException("Timeout trying to receive [%s]" % buffer)
microbit.repl.repl.REPLException: Timeout trying to receive [
raw EPL; CTRL-B to exit
>]

全输出：
