PN7160 DPC check

[Alb]

Hi,

I'm trying to setup dpc on pn7160 (AN13224) but when I select "12"->DPC Check on "NfcFactoryTestApp" I get the answer "Error, cannot get parameter value". Buffer received is 4F 3F 01 09. Can you tell me which is the reason of failure and most important where I can find this info in nxp docs?

Thanks

Alberto

Hi Daniel,

I will check parameters but can you tell me the meaning of device answer I reported for "DPC check" command in the app? I would like to have a clarification about it becasue using this setup reader works perfectly....

Thanks

Alberto

Hello mark_tang, 

I see your PN7160 FW version is 12.50.05

As Alberto has mentioned, the DPC Check has been added from version 12.50.06.

I am sorry that I overlooked this fact. I assumed that the FW you have is 06 or higher. 

So the DPC is working but the DPC command is not supported for the 05 FW version. 

The FW update can be done as described here: 

The latest FW, you can find it here -> https://github.com/NXP/nfc-NXPNFCC_FW/tree/master/InfraFW/pn7160

More description of how to do the FW update is available in PN7160 FAQ document -> 19 FW update
