Not able to mount using BTLE

❯ python3 fzfs.py -a MACADDR -m /home/user/fzmount
Traceback (most recent call last):
  File "/home/user/src/fzfs/fzfs.py", line 63, in <module>
    main()

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "<frozen genericpath>", line 19, in exists
TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

I tried the following to troubleshoot a bit

import serial
import serial.tools.list_ports
import serial_ble
bluetooth = serial_ble.BLESerial(MACADDR, '19ed82ae-ed21-4c9d-4145-228e61fe0000', '19ed82ae-ed21-4c9d-4145-228e62fe0000')
print(bluetooth)

which yielded the following

Traceback (most recent call last):
  File "/home/user/src/fzfs/t.py", line 5, in <module>
    print(bluetooth)
  File "/home/user/.virtualenvs/fzfs/lib/python3.11/site-packages/serial/serialutil.py", line 532, in __repr__
    'rtscts={p.rtscts!r}, dsrdtr={p.dsrdtr!r})'.format(
                                                ^^^^^^^
AttributeError: 'BLESerial' object has no attribute 'is_open'. Did you mean: 'isOpen'?

Using the cable with my FZ works fine.

Please let me know if there's anything I can try to help debug this.

Hm, weird. Could this be a dependency issue? Did you install from requirements.txt?
