checkGenuine returns Invalid status 6814 (Unknown reason)

Hello, I'm trying to check a Nano S on firmware 2.0.0 by running

python3 -m ledgerblue.checkGenuine --targetId 0x31100003

The docs indicate that 0x31100003 is correct for my firmware: https://support.ledger.com/hc/en-us/articles/4404382029329-Check-hardware-integrity?support=true.

I'm getting the following error

Traceback (most recent call last):
  File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/runpy.py", line 193, in _run_module_as_main

ledgerblue.commException.CommException: Exception : Invalid status 6814 (Unknown reason)

When I try checkGenuineRemote it works.

python3 -m ledgerblue.checkGenuineRemote --targetId 0x31100003

However, the docs indicate the checkGenuineRemote is the right script for a Nano X, not a Nano S. What's even more confusing is when I run the command listed for the Nano X (which has a different targetId) on my Nano S, it also tells me the device is genuine:

python3 -m ledgerblue.checkGenuineRemote --targetId 0x33000004

What's the right command to use for a Nano S running firmware 2.0.0?

Start with ledgerblue/checkGenuine.py and ledgerblue/comm.py, using the reported checkGenuine and checkGenuineRemote commands as entry points. Compare how target IDs and returned status codes are handled for Nano S firmware 2.0.0, then verify the documented command and its genuine-device result.
