fido-authenticator: “up needed” not signaled on NK3AM

[robin-nitrokey]

one curious thing is that I get the prompt to touch the device in the 3A NFC but it doesn't prompt with 3A mini
It seems if status == STATUS.UPNEEDED: # Waiting for touch this call in python-fido2 isn't called on the 3aMini

Nitrokey/pynitrokey#274

I also have the feeling that this #94 is also related to the issue here and the firmware is missing something - although I have no way to test what's going on at the hardware/firmware level
my feeling comes from the fact that the 3ANFC just works and perhaps this is related to nrf52 vs lpc55

In combination with #93, my guess that there is something wrong with the timers that trigger the ctaphid_keepalive and ui tasks: the CTAPHID_KEEPALIVE command signals STATUS_UPNEEDED, and ui should call the code that toggles the LED if it is blinking. @daringer do you have an idea why this could be the case? I will also try to debug this while working on #79.

looks like this is also fixed by #319

based on the original issue (Nitrokey/pynitrokey#274) I tested using nitropy fido2 verify and both behave identical now:

• nk3am:

❯ nitropy fido2 verify
Command line tool to interact with Nitrokey devices 0.4.38
Enter PIN: 
Touch your authenticator device now...
/../

• nk3an:

❯ nitropy fido2 verify
Command line tool to interact with Nitrokey devices 0.4.38
Enter PIN: 
Touch your authenticator device now...
/../

so, should we close this as fixed?

AFAIS this is fixed in current firmware releases, so I’m closing this issue. Please re-open if the problem occurs again.
