https://community.nxp.com/t5/NFC/NFC-Simulation-Card-Response-Issue-with-TagWriter/m-p/2327561#M14100 <P>I am currently using the development kit of LPC55S69 + OM27160A to debug the NFC simulation card. When using TagWriter to read the tag information, the response is not timely or even there is no response at all. However, using the NFC service provided by the phone can respond promptly and read the tag information. I am running the nfc_example_RWandCE.c in the NXP-NCI2.0_LPC55S6x_examples. Even if I turn off MODE_POLL, the situation is still not satisfactory. It seems to be constantly in a loop of detecting the device status for the first time. Please help provide some troubleshooting suggestions. Thank you very much.</P> Fri, 06 Mar 2026 06:25:04 GMT zhaoheng 2026-03-06T06:25:04Z https://community.nxp.com/t5/NFC/NFC-Simulation-Card-Response-Issue-with-TagWriter/m-p/2327561#M14100 <P>I am currently using the development kit of LPC55S69 + OM27160A to debug the NFC simulation card.
