Hi, I'm using the PN7150 NFC controller in my design. We are presently in the process of performing certification of my product and we are required to test the NFC by switching across the different types/modes - type A, B, F and continuous TX (CTX).

Is there a software tool that NXP already has developed? If yes, can that be shared?

Dear,

We currently don’t have a software tool capable of performing the switching among the diverse types/modes. Nevertheless, there is a way you can manage to carry out that task, by modifying the polling loop in PN7150.

It can be modified in nfc_task.c by re-structuring this section:

unsigned char DiscoveryTechnologies[] = {
     MODE_POLL | TECH_PASSIVE_NFCA,
   MODE_POLL | TECH_PASSIVE_NFCB,
   MODE_POLL | TECH_PASSIVE_NFCF,
};

Regards,

Ivan.
