Cannot detect Yubikey 5 NFC with PN532
agorgl opened this issue · 11 comments
I have a PN532 module plugged in HSU (UART) mode with a usb serial adapter.
Using nfc-poll -v and scanning various RFID cards and tags works flawlessly, but trying to scan a YubiKey 5 NFC doesn't read anything.
I tried two different PN532 modules, one ITEAD PN532 NFC MODULE and an ELECHOUSE NFC RFID MODULE V3 that exhibit same behavior.
Any idea on how to debug / diagnose the problem?
Scanning yubikey with NFC Tools on Android it shows up as having a tag type of ISO 14443-4 with the description NXP - Mifare Plus. Same behavior is observed with another (train) nfc card that I have with tag type of ISO 14443-4 and description NXP - Mifare DESFire EV1 4k.
Are these kinds of cards supported by libnfc / nfc-poll?
I also tried using another USB UART / TTL adapter, even serial over BT with a HC-05 module, powering module with separate supply etc. just to be sure that it was not the problem of any other component in the equation.
Did you find out anything?
Nop, I kinda gave up after a while (I even tried to make my own NFC antenna!).
I think that these cheap PN532 modules are not powerful enough to interact with Yubikey NFC / Mifare DESFire EV1 4k cards
I have it detecting a Yubikey 5 NFC just fine, even via pcsc_scan. (Running on a Raspberry Pi 4 with PN532 connected via i2c) It also works just fine with a Codewave NFC Micro Sticker Tag, so this isn't a size or antenna issue.
libnfc + ifdnfc built from source using latest master of both repos.
I tried only using uart, can you try and tell us if it works with uart too? If so, what board do you have exactly?
Can't test UART at the moment, but it's this board here
https://a.aliexpress.com/_mqQRXte
It also detects the yubikey with plain old nfc-poll.
Are you sure this is your board? Because I have a similar chinese board that looks exactly the same, and I could not make yubikey scanning work with it in UART mode
That's the exact board that I am using.
I actually have a second one coming in a few days, so can see if ur works the same and also test UART mode.
So I just checked and basically the quality varies dramatically between these cheap clone boards from AliExpress or Amazon... One of them ones that I have here has very poor range and struggles to even reliability detect full sized smart card, let alone a Yubikey...
Even from the same seller/vendor?
Haven't tried but I would imagine so, these clones are never consistent...
