Filed to emulate NFC #1611

Closed gushmazuko closed 2 years ago

gushmazuko commented 2 years ago

The bug

NFC emulation has stopped working since the 0.63.3 update. In the release notes you can see NFC: completely redesigned application, improvement ..., I guess the problem is here. I rolled back to the previous firmware 0.62.1 and the emulation works fine. Then I updated to 0.63.3 again, the emulation doesn't work again. Same with 0.64.3 & dev b3d7583f.

After each update I read the tag again.

Reproduction

  1. Read Mifare DESFire tag
  2. Save
  3. Emulate

Hello @gushmazuko , thanks for report, working on it. You have the problem with emulating DESFire tag UID, am I right?

Yes exactly.

I am actually having the same issue but with saving/emulating a Mifare Classic UID. I can emulate the UID from my capture file I took whilst on a previous firmware version, but a new read/save of the same card on the current firmware results in no "Emulate UID" option, just "Emulate" which doesn't work.

I have the same problem. Trying now to scan the emulated nfc from the flipper zero with my android phone.

Same issue with every Miflare Classic 1K that used to work before, example

UID: 04 30 66 62 5B 55 80
ATQA: 00 44  SAK: 08
Keys Found 32/32
Sectors Read 16/16

Firmware 0.65.2

Hello @gornekich, do you think this will also fix #1468 (Mifare Classic 1K) or is it another issue than this DESFire one ?

It works fine, thank you!
