[PN7150] Can Not Get The NDEF Write During Card Tag Emulation

kennyliao — Wed, 22 Apr 2020 04:06:25 GMT

Hi Experts,

We used the application "NXPNCI-K64F_example" from "NXP-NCI_MCUXpressoExample_V1.5.zip" and configured it into "Card Tag Emulation" Only (CARDEMU_Support). And our final target is to write an NDEF message into the Tag from a remote reader.

But we encountered a problem that relates to NDEF Write from remote NFC Reader (Smart Phone APP "NXP" ).

Thus, we tried to set a breakpoint in the NDEF Status Machine Case "T4T_NDEF_EMU_Write" and put the Reader near the Tag to write an NDEF message, the case "T4T_NDEF_EMU_Read" was reached, but the case "T4T_NDEF_EMU_Write" does not ever into this case. The Case "T4T_NDEF_EMU_Write" command content that is "0x00, 0xD6", but we certainly do not see it. Do I misunderstand? Or miss something need to modify?

Please help us, Many Thanks.
