Reader trace but Not tag trace
i have a proxmark3 with:
bootrom: svn 412
os: svn 412
FPGA image built on 2009/12/8
and a reader ACR1281U
when i try to snoop whit command "hf 14a snoop" and then "hf 14a list", i get the next trace:
ETU rssi who bytes

I can't see any TAG trace. I tried changing distances btw reader/antenna/tag and it doesn't work... 
Any ideas?
Thank you!

Re: Reader trace but Not tag trace
Try an antenna with better tuning values. If nothing works, just simulate the tag and see what the reader communicates to you.

Re: Reader trace but Not tag trace
i tried whit two different antennas, (tuning values: 11,28v and 10.09v) but i continue without tag trace.
simulating the tag, i get: Reader requested we HALT!
is it possible that the reader block tag trace when snooping?
i don't have idea of what it's wrong...
Thanks
