So we have identified the PN7150.</P><P></P><P>Our problem is the "linux_libnfc-nci" provided by NXP. Normaly it's compatible with i2C-dev driver kernel but we can't instanciate multi node with this library (many static and hard coded). Have you solution to use your library with 3 readers without rewrite all library?</P><P><BR />Have you another component with this standard with a library where we can instantiate multi readers?</P><P></P><P>Thank you :smileywink:</P></BODY></HTML> Thu, 04 Apr 2019 14:04:26 GMT thomas_villeboe 2019-04-04T14:04:26Z pn7150 - multi node in one linux application https://community.nxp.com/t5/NFC/pn7150-multi-node-in-one-linux-application/m-p/879875#M5107 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P><BR />We have application which use 3 readers PN5xx with library "libnfc" in uart interface.</P><P><BR />Now we want upgrade this solution with the support of ISO15693.
