Re: [requests] What would you like to see next on proxmark3 ?

Ive tried this with many different tags and thresholds and always get the same result. This was tested with a good ioprox.

Re: [requests] What would you like to see next on proxmark3 ?

hmmm looks like someone added a timeout in the lf search ...  roll

it appears you'd have to run:
lf read

once tag was read:
data samples
lf search 1

for the threshold to work currently...

add it to the list... sad

Re: [requests] What would you like to see next on proxmark3 ?

For the next hardware version, i like to see..

* On/off power button, so i dont have to pull out the usb kabel when it locksup or just dont work

* Some input/output pins to add external sensors there can be used by the proxmark3 lua code, like be able to connect color light sensors to the pins for detecting when external rfid kaypad it having an red/green led, sound sensor for beeps

* UHF range 8xxmhz(or some thing) for both the US and EU range

Better late than never.  I've scratched it out for you.

That is fully possible.  As long as you can manually demod the snoop.

@lohcm88,  if you look at my fork,  I've a timestamp part commented out from the code.  The logfile looks like crap when its enabled but thats what you are looking for. I think it was in client/util.c  "addtologfile"

Or have a look at AddLogCurrentDT() in client/util.c and make use of it. In official repository too.

No, it is not directly available to end users. But it is only a few lines of code away...

Re: [requests] What would you like to see next on proxmark3 ?

Hello,

I was curious that just by using send command., can we perform below communication?

R: 26                                    => Welcome (REQA) (or use WUPA = 0x52)
T: 44  03                                => Respond (ATQA)
R: 93  20                                => Select cascade 1 (SEL)
T: 88  04  34  74  cc                    => CT, UID(byte 1,2,3), BCC
R: 93  70  88  04  34  74  cc  0e  05    => Select available tag (SEL)
T: 24  d8  36                            => Select Acknowledge (SAK)
R: 95  20                                => Select cascade 2 (SEL)   
T: e1  e3  1c  80  9e                    => UID(byte 4,5,6,7), BCC
R: 95  70  e1  e3  1c  80  9e  b9  e1    => Finish select (SEL)
T: 20  fc  70                            => SAK without cascade bit set
R: e0  50  bc  a5                        => Request Answer to Select (RATS)
T: 06  75  77  81  02  80                => ATS (DESFire EV1)
R: 50  00  57  cd                        => Disable (HALT)

If not, It would be great to see that in proxmark3 by just having simple command to send above communication.

Regards,
Jk123

@Jk123 Please don't double post.  The hf 14a raw cmd is what you are looking for.
