NFC type-4 tag is not able to respond PPS request. and How to update the ATS response.

[Bhavesh Shah]

Hello there,

I am facing some difficulties while using nRF52832 NFC for an application.

When I tap the nrf52832 device on the NFC reader the nrf52 cannot able to respond to the PPS request.

As per the document International ISO/IEC 14443-4:2000(E) Standard (http://www.emutag.com/iso/14443-4.pdf) page number 5, Figure 1 — Activation of a PICC Type A by a PCD, the NFC reader can request for some parameter changes at nRF52 side with PPS request. In its replay NFC card (nrf52832 in this case) needs to respond with PPS response.  But it is not responding to PPS request. 

Is any way to configure it. 

is there any way to change the ATS response in nRF52832.

Hello,

What did you program the nRF with? Did you use one of the examples from the SDK? In that case, which SDK version? Please note that the NFC on the nRF2832 is ISO/IEC 14443-2 (not sure if there is any difference).

Best regards,

Edvin
