[SOLVED] OTA Not Working

[JuanMa]

Hi all,

I am trying to use OTA Wifi following the documentation, but when the device requests the manifest, an error ocurrs:

File "OTA_server.py", line 156, in do_GET
    manifest = generate_manifest(current_ver, host)
  File "OTA_server.py", line 287, in generate_manifest
    to_delete, new_files, to_update = get_diff_list(current_ver, latest)
  File "OTA_server.py", line 215, in get_diff_list
    right_paths = get_all_paths(right, ignore=ignore)
  File "OTA_server.py", line 201, in get_all_paths
    paths += [os.path.join(d, f) for f in files]
  File "OTA_server.py", line 201, in <listcomp>
    paths += [os.path.join(d, f) for f in files]
  File "/usr/lib/python3.5/posixpath.py", line 89, in join
    genericpath._check_arg_types('join', a, *p)
  File "/usr/lib/python3.5/genericpath.py", line 143, in _check_arg_types
    (funcname, s.__class__.__name__)) from None
TypeError: join() argument must be str or bytes, not 'NoneType'

I have followed it and the problem seems to be that the method os.walk(path) returns None as dirpath. Am I doing something wrong?

PD: The files inside the script folder are these:

ServerFiles-->
               OTA_Server.py
               firmware_1.0.0.bin
               firmware_1.0.1.bin

Thanks,

JuanMa

@JuanMa I am currently trying the same, also referencing this video from Pycom: https://www.youtube.com/watch?v=NnUVYIedl_w

When i run the HTTP server from the OTA folder in pycom-libraries-master/examples/OTA the folders are already in place, but i get same error as you! What did you do to solve it precisely?

Thanks

Problem solved. It is mandatory to create the version folders.
