NFC P2P using EXP-MSP430F5529+TFR7970ATB & TRF7970AEVM

Other Parts Discussed in Thread: MSP430F5529, CC2541

Hello,

I'm trying connect EXP-MSP430F5529+TFR7970ATB & TRF7970AEVM by NFC P2P. EXP-MSP430F5529 is passive target 106 kbps and TRF7970AEVM is initiator. Fw for EXP-MSP430F5529 is MSP430F5529_P2P_Demo. 

I send anticollision command using TRF7970 EVM control GUI (page 14443A). IRQ_STATUS_COLLISION_ERROR appears each time for EXP-MSP430F5529 . So, is it possible link the devices by NFC P2P? If yes, how do it?

Thanks,

Alex.

    Dear Alex,

    It sounds like you are using the Card Emulation Reader tab on the EVM GUI. The ISO14443A tab is for reading Card Emulation type A and does not have P2P commands. Try using the using the commands within the NFC-PP tab to handle the anti-collision instead. All of the P2P functionality of the GUI is within that tab.

    Refer to section 2.9 of the EVM user guide for details on how to use the P2P interface of the GUI: http://www.ti.com/lit/ug/slou321a/slou321a.pdf

    Hello Ralph,

    Thanks for your advise. If  I use commands within the NFC-PP tab  I have folllowing message:

    "Set new target CID number".

    correct - this will never work - as the firmware in the TRF7970AEVM as it ships was written well before NPP, SNEP and LLCP were created and then used.

    we are in the process of backporting portions of the P2P code to the TRF7970AEVM, but this will take some time as resources are limited for this activity. Is this a requirement for you to have the TRF7970AEVM as part of your demonstration/evaluation?  Perhaps the better question is: Do you need a P2P solution with a lower end MCU involved?

    Hi Josh,

    My target is porting the NFC P2P for TRF7970ATB from MSP430 to CC2541. I've got this part from MSP430F5529_P2P_Demo f/w and ported it to CC2541 f/w. Now I'd like understand how to work NFC P2P on MSP430F5529 board. So I need other part for P2P connection and I take TRF7970AEVM.

    A question about the log: what does "()" mean?

    For example:

    23:59:14.811    --> 010D000304A208010203080000
    23:59:14.971    <-- 14443A Select.

    Dear Alex,

    If you are trying to experiment with how to use NFC P2P with the 5529 you could get our Launchpad and Boosterpack bundle which has a DLP-7970A and a MSP430F5529: https://estore.ti.com/nfclink-bndl.aspx

    With that hardware you can use the LaunchPad build option in CCS for the P2P demo you already have.

    Josh,

    I am having the same problem.  Whenever I try to communicate in NFC-PP mode, I get the message "Set new CID number".  I really want to duplicate this function in the EVM to get an idea of range and alignment requirement.

    What can I do to make this work as shown in the TRF7970AEVM Users Guide?
