Topic: ACR122U: nfc-emulate-* noob questions.

Hi, i'm starting to work with libnfc(1.4.2) and i would like to know some info about tag emulation on ACR122U.
Libnfc comes out with 3 tools:
nfc-emulate-forum-tag4
nfc-emulate-tag
nfc-emulate-uid

I have to emulate a MFC with 4byte UID(need many attempts with different UIDs ) and i have some some doubts:
-Which tool should i use? emulate-uid or emulate-tag?
-What's an initiator and how should i use it?
Basically i'm trying to change cards' UIDs to study A/B keys generation algo, that's based on UID. I want to make a byte-a-byte change on UID to find which bytes are involved in keys generation.

Thanks!

Hello,

First 1.4.2 is not supported anymore, please use the last stable version 1.7.x.
Next, please read manual pages of these tools :-), thanks.
