Topic: Problems with nfc-emulate-forum-tag2 using PN533/Nexus S
I’m trying to execute nfc-emulate-forum-tag2.exe with following working environment:
Device: PN533 v2.7 / Nexus S (Android 2.3.3)
OS: Windows 7 32bit
Code revision: 1134
Build environment: TDM-GCC-4.5.2, libusb-win32 1.2.5.0, CMake 2.8.5
[Problem 1]
The program usually receives a HALT command after the first 4 blocks were sent.
Connected to NFC device: NXP / PN533 - PN533 v2.7 (0x07)
Emulating NDEF tag now, please touch it with a second NFC device

HALT sent
ERROR C:\Src\libnfc\examples\nfc-emulate-forum-tag2.c:143
Software caused connection abort (103)
nfc-emulate-forum-tag2.exe: Success
Such situation remains even the memory area is modified by the example given on Page 31 of NFCForum-TS-Type-2-Tag_1.0.

By the way, the program sometimes can receive another unknown error as following:

Emulating NDEF tag now, please touch it with a second NFC device

Unknown command: 0x93
ERROR C:\Src\libnfc\examples\nfc-emulate-forum-tag2.c:143
Unknown error (134)
nfc-emulate-forum-tag2.exe: Success
Did I miss anything or do anything wrong?
[Problem 2]
I tried to directly put the Nexus S on PN533, and executed the nfc-emulate-forum-tag2.exe again and agan. Sometimes the program hangs as following:
Connected to NFC device: NXP / PN533 - PN533 v2.7 (0x07)
Emulating NDEF tag now, please touch it with a second NFC device
And at this moment, the NFC TagInfo 1.04 running on Nexus S can collect a JIS-X 6319-4/FeliCa tag like https://picasaweb.google.com/lh/photo/T … directlink.
Shouldn’t the chip emulate a ISO/IEC 14443-3 tag?
[Problem 3]
If the initialization of .nbr is assigned to NBR_424 or NBR_106 instead of NBF_UNDEFINED, the program will always hang like what is shown in Problem 2. The NFC Tag Info now collects a ISO 14443A tag like https://picasaweb.google.com/lh/photo/n … directlink.
Does someone have any idea about this?
Any help would be highly appreciated.
