libllcp: "Invalid Received Frame" (13), returned error: "RF Transmission Error" (-20)) when receiving vcard

[Victor Palacio]

Hello,

I'm trying to send a vcard contact to a NFC reader using libllcp. The phone is a samsung S3 (GT-I9300).

I tested snep-server example application with 2 different readers; SCL3712 (PN53x driver) and ADRBv2 (arygon driver).

Both tests return same error when I touch to beam a contact:
...

debug    libnfc.chip.pn53x    Chip error: "Invalid Received Frame" (13), returned error: "RF Transmission Error" (-20))
...
or
...

debug    libnfc.bus.uart    RX: 91 00
debug    libnfc.chip.pn53x    Chip error: "Invalid Received Frame" (13), returned error: "RF Transmission Error" (-20))
...

Can anybody give me a hint about this error?

Regards,

I tried also libllcp branch 'socket', with same result.

I'm using libnfc 1.7.1.

Here is libllcp log for this problem... Looks like an underlying libnfc problem, but i'm just guessing...

Could you first try snep-client, then try snep-server to see what happens?

What Android app must I use to do this test? What is trying to send snep-client? Looks like a SmartPoster URL to me. I'm not sure how can Contacts App manage that info.

This is the log when I try to use Contacts while executing snep-client:

Maybe the problem is a response length limit?

When using command TgInitAsTarget, I assume MIFARE params and FELICA params does not apply.

General Bytes are; 14 (20 bytes) 46 66 6d 01 01 11 02 02 00 80 03 02 00 13 04 01 60 07 01 03... there are no TKBytes (TKLen = 0x00).

What are the meaning of this bytes?. Is there the reason for my problem? I cannot find nothing about general bytes in PN532 manual.

[Victor Palacio]

I succeded (somehow) to receive only short contacts.

¿There is a limit condition for data with snep-server example? I cannot find anything about that.
