I cloned the repo, and I'm following the Developing Solo (No Hardware Needed) section of the readme.

After I run ./main, the terminal output is

[STOR] Auth state is initialized
[STOR] pin not set.

If I run python tools/ctap_test.py, the output shows

Test init
Traceback (most recent call last):
  File "tools/ctap_test.py", line 828, in <module>
    t.test_hid()
  File "tools/ctap_test.py", line 156, in test_hid
    r = self.send_data(CTAPHID.INIT, '\x11\x11\x11\x11\x11\x11\x11\x11')
  File "tools/ctap_test.py", line 85, in send_data
    return self.dev.call(cmd, data, event)
AttributeError: Tester instance has no attribute 'dev'

Then, if I run python python-fido2/examples/credential.py, the output says
No FIDO device found

Not sure what the desired outputs should be - could you help troubleshoot what's going on? (Not sure if this matters, but I have Mojave). Thanks!

Hmm, did you install our patched version of python-fido2? Is the repo up to date?

I see in master version of tools/ctap_test.py, test_hid() is commented out.

if __name__ == '__main__':
    t = Tester()
    t.find_device()
    # t.test_hid()
    # t.test_long_ping()
    t.test_fido2()
    # t.test_rk()
    # t.test_responses()
    # test_find_brute_force()
    # t.test_fido2_simple()
    # t.test_fido2_brute_force()

I'm guessing for your case, for some reason, t.find_device() is commented out

I believe I installed the patched version of python-fido2 (head at 329434f).
I checked tools/ctap_test.py and noticed I was running t.test_hid() instead of t.find_device() because I was fiddling around with it. Whoops. Now when I run python tools/ctap_test.py, I get

[]
Traceback (most recent call last):
  File "tools/ctap_test.py", line 827, in <module>
    t.find_device()
  File "tools/ctap_test.py", line 73, in find_device
    raise RuntimeError('No FIDO device found')
RuntimeError: No FIDO device found

A step that I forgot I did about: I changed line 75 in pc/device.c from

    serveraddr.sin_port = htons( 8111 );

to

    serveraddr.sin_port = htons( 0 );

to fix an error that said bind failed: Address already in use. Also did the same in tools/http2udb.py line 44 (udpport = 8111 -> udpport = 0). I wonder if the issue is something to do with which ports tools/ctap_test.py is using to find the device.

[conorpp]

The bind failed: Address already in use was due to an error with the routine being called twice. Just merged this PR which should fix it.

#58

I would revert serveraddr.sin_port = htons( 0 );, it must be 8111.

[meganchen]

Sweet. Thanks! The bind failed: Address already in use error is gone now. I'm still getting RuntimeError: No FIDO device found. Not sure what else to try

@meganchen Perhaps 'Simulated device' section in nucleo board documentation would help you (if it has not gone stale already).
My guess is, that you are not using the bundled modified python-fido2 library, but the original one. You need to install the bundled sources in a virtual environment, and run it from there.
