CCS/CC3200_NFC_CARD_READER: NFC Demo not detecting NFC Cards

Part Number: CC3200
Other Parts Discussed in Thread: TRF7970A, , MSP430F5529

Tool/software: Code Composer Studio

Hi All, I have a CC3200 Launchpad (Rev 4.1) and a TRF-7970ABP NFC Booster Pack (v4.7) I’m trying to follow www.ti.com/.../tidua70.pdf It all works until I try to scan any NFC card. Nothing detects unfortunately as per this thread: e2e.ti.com/.../518595 Out of interest, I tried running the demo without the TRF7970A Booster pack connected and the result is the same! Any ideas on how I can start detecting NFC cards? Thanks in advance! Cheers, Tim

    Tim -

    the demo will start looking for tags only after the device is put into the station mode (see flow chart on page 6), after following the steps in the design guide -

    you can use the nfc.usf file found here to program the device ==> here is where i put the addon and where that file is:

    C:\ti\CC3200SDK_1.3.0\cc3200-sdk\example\nfc_reader\html

    this is handy because the html files (for the http server page needed for putting the demo into Station mode needed to come up corrrecty) are added, etc. already   - when its looking for tags, the green LED will be flashing and the terminal will look like this. (below)

    Hi Josh,

    I've been through the process you've mentioned, and can get the device to show that it is ready to accept an NFC card:

    In this state, the green light on the booster pack is not blinking and the NFC card is not detected at all.

    The code I'm using was downloaded from here: www.ti.com/tool/cc3200_nfc_card_reader 

    I noticed the code you've mentioned is in C:\ti\CC3200SDK_1.3.0\cc3200-sdk\example\nfc_reader\html, however the installer on the website actually installed this example application into a lower SDK version directory C:\ti\CC3200SDK_1.1.0\cc3200-sdk\example\nfc_reader\html. I'm not sure if that matters though.

    I think the problem is stemming from the version of the booster pack that I'm using, since the IRQ pin has changed between versions. This is discussed here: e2e.ti.com/.../518595. Unfortunately it was not resolved.

    As a side note, can you confirm that the CC3200+TRF7970A is not supported with the NFCLink application?

    Anyway, thanks for your help so far, hopefully I can work out the pin muxing or whatever the issue is and get scanning!

    Cheers,

    Tim

    Tim - 

    i think you need to move the solder blob on the BP.

    see page 2 here

     with regards to NFCLink - this was created to work first on MSP430F5529, for integration into an Android or Ubuntu system 

    what is your system requirement? 

    are you using Android or Ubuntu? if not, you can use the standalone version for MCUs

    or the Linux Kernel based version
