Hello!
I am currently debugging an application using the PN7160 in Cardmode. Below are the NCI message logs from NfcLibrary.
NCI << 61 23 00
(NxpNci_WaitForDiscoveryNotification())
NCI << 61 05 0c 01 02 04 80 ff 01 00 80 00 00 01 80
(NxpNci_ProcessCardMode())
NCI << 61 06 02 01 01 (RF_DEACTIVATE_NTF)
NCI >> 21 06 01 00
NCI << 41 06 01 00
NCI >> 21 03 05 02 80 01 81 01
NCI << 41 03 01 00
From what I understand after receiving RF_INTF_ACTIVATED_NTF the next message is RF_DEACTIVATE_NTF which causes it to return to wait for RF_INTF_ACTIVATED_NTF instead of exposing the registered NDEF message to the NFC reader.
- Is my understanding correct?
- What could be the cause of this behaviour? An incorrectly matched antenna?
- Can I find some tool to decode NCI messages so that I don't have to dig through the NFC Controller Interface Technical Specification?
