Hi,

I got some problems to communication with Blackberry Bold 9900 NFC. I used NXP PN533 simulate Type Tag 2, 9900 detected it but can't recognize it. I used the NFC-forum standard tag format, here is the memory setting table:

0x00, 0x00, 0x00, 0x00, // Internal Manufacturing use

0x00, 0x00, 0x00, 0x00, // Internal Manufacturing use

0x00, 0x00, 0xFF, 0xFF, // Block 2 (Static lock bytes: CC area and data area are read-only locked)

0xE1, 0x10, 0x06, 0x0F, // Block 3 (CC - Type 2 version 1.0, Data area 48 bytes, Read-only mode)

0x03, 0x27, 0xD9, 0x02, // T =0x03, L=0x27

0x20, 0x01, 0x53, 0x70, //Smart Poster ID: 0 Length = 0x20

0x30, 0x99, 0x01, 0x0b,

0x01, 0x54, 0x31, 0x05, //Text ID: 1 Length = 0x0b “Title”

0x65, 0x6e, 0x2d, 0x55,

0x53, 0x54, 0x69, 0x74,

0x6c, 0x65, 0x59, 0x01,

0x09, 0x01, 0x55, 0x32, //URL ID:2 Length = 0x09 “www.abcd.com”

0x01, 0x61, 0x62, 0x63,

0x64, 0x2e, 0x63, 0x6f,

0x6d, 0x00, 0x00, 0x00,

0x00, 0x00, 0x00, 0x00,

Thanks for your kindly help.

Exactly what type of tag are you emulating? Not all tags are alike; for example, NXP supports a proprietary format for MiFare Classic to store NDEF content. We are unable to read such MiFare Classic tags due to licensing constraints.

Hi Jomurray,

Thanks for your response, Unfortunately we just used NXP Mifare Classic Tags to do that... Also we want to know which type is ok, if its possible with NXP MIFARE Ultralight or any other types?

Best Regards

MiFare 1k and 4k tags are not supported due to licensing constraints. The same licensing constraint applies to MiFare Plus tags and DESFire tags in MiFare mode (DESFire tags also support ISO7816-4 mode and these are supported). MiFare Ultra Light,and Ultra Light C are supported since they are not subject to licensing constraints.

So thanks for your information. We had confused with this issue for a long time. BTW, we have an additional question about  your NFC, how could we working with your LLCP, is that also base on NFC-DEP?

[jomurray]

LLCP and SNEP (over LLCP) from the NFC Forum set of specs are planned. They are not available in the current relase (7.0) but are currently planned as part of he Peer-2-Peer feature which should be coming soon. I can't be more specific about dates. There is a good deck on this and other NFC material that was presented at the latest DevCon11 confernce (entitled: "NFC:  The Future of Apps and How to Build an NFC Enabled App").

You might also like to have a look at a couple of articles that I wrote with my colleague on developing NFC applications on the BlackBerry platform.

We plan more in the series!

Yes, I understand what you mean, but we got your latest release version 7.1 Bundle 168(v7.1.0.64), if LLCP avaiable on this? BTW, what's your NFC hardware model? Thanks for your kindly help. BR
