Hello, could you advise how to configure the NFC antenna current for PN7220 via libnfc-nxp-rfExt.conf or other configuration files? Our tests show the antenna current is too high and needs to be reduced.
Hello @zhangkai
Recommends to enable DPC , but before enable DPC,which needs to be calibrated.
Hello @zhangkai ,
If you only need to reduce/limit the current, you can do it in the same way as described here: https://community.nxp.com/t5/NFC-Knowledge-Base/PN7642-Basic-RF-power-limitation-using-DPC/ta-p/2187...
