.SH DESCRIPTION

|
|
|
|
.B nfc-poll
|
2010-10-08 22:01:47 +02:00
|
|
|
is a utility for polling any available target (tags but also NFCIP targets)
|
|
|
|
|
using ISO14443-A, FeliCa, Jewel and ISO14443-B modulations.

This tool uses hardware polling feature if available (ie. PN532) or switch back
|
|
|
|
|
to software polling, it will display available information retrieved from the
|
|
|
|
|
tag.

.SH IMPORTANT
|
|
|
|
|
There are some well-know limits with this example:
|
|
|
|
|
- Even with NDO_AUTO_14443_4A enabled (default),
|
|
|
|
|
.B nfc-poll
|
|
|
|
|
can miss ATS. That due to the way the PN532 use to poll for ISO14443 type A, it
|
|
|
|
|
will attempt to find ISO14443-4-only targets, then ISO14443-3. If your
|
|
|
|
|
ISO14443-4 target is present when PN532 looks for ISO14443-4-only, ATS will be
|
|
|
|
|
retrieved. But if your target enter the field during ISO14443-3, RATS will not
|
|
|
|
|
be sent and ATS not retrieved.
|
|
|
|
|
-
|
|
|
|
|
.B nfc-poll
|
|
|
|
|
can show up only one card while two are in field. That's due, again, to the way
|
|
|
|
|
the PN532 poll for targets. It will stop polling when one modulation got a
|
|
|
|
|
result, so if you have, for example, one ISO14443-3 (eg. Mifare Ultralight) and
|
|
|
|
|
one ISO14443-4 (eg. Mifare DESFire), it will probably return only the
|
|
|
|
|
ISO14443-4.
