hf mf sim not working reliably #271

Closed fabled closed 5 years ago

fabled commented 5 years ago

I just got my proxmark3 rdv4.0 and I am testing mifare side things. It seems the 'hf mf sim' is not currently working reliably. I tested the following:

What happens is that the A-led keeps blinking when close to reader, but the reader is unable to select the emulated token. Occasionally the reader is able to select the token I am emulating.

Perhaps this is due to the fact that 'hf 14a sim' and Proxmark official git master 'hf mf sim' are using prepare_allocated_tag_modulation() + EmSendPrecompiledCmd() for the initial handshake (anticollision + selection) allowing faster responses, where as this branches' 'hf mf sim' is using the plain EmSendCmd(). I suppose this causes timing differences that making it work unreliable against some readers.

aha... when it comes to RDV4, I suggest you look in https://github.com/RfidResearchGroup/proxmark3 dedicated repo.

And yes, iceman fork hasn't gotten the remake of sim from official repo yet.
