Hi, unfortunately, the NFC Forum specifications are only free of charge for members. If you are not a member, you need to purchase them and they are expensive.

Some years ago they were still free of charge on their website, so many older website/articles still refer to them as such but they are no longer available.

Here is my github repository for a PN7150 driver. Could be usefull to answer some questions on NCI you have.

Enable Low Power Card Detection Mode ,i learn from https://www.nxp.com.cn/docs/en/application-note/AN11757.pdf

There is my code , uint8_t NxpNci_CORE_CONF_EXTN[]={ 0x20, 0x02, 0x0D, 0x03, /* CORE_SET_CONFIG_CMD */

0xA0, 0x40, 0x01, 0x00, /* TAG_DETECTOR_CFG */

0xA0, 0x41, 0xFF, 0x04, /* TAG_DETECTOR_THRESHOLD_CFG */

0xA0, 0x43, 0x00, 0x50 /* TAG_DETECTOR_FALLBACK_CNT_CFG */

};

Oscilloscope screenshot as follow, i know that it is regular mode , i guess it may be my configuration problem. To verify my problem, I want to know the answer when i send NxpNci_CORE_CONF_EXTN[].

Thank you for your guidance.
