PN532 InDataExchange analog in PN7150

[superoriginalma]

I am porting in-house library for reading desfire tags from old reader (PN532) to newer one(PN7150). This library works over InDataExchange command of PN532. I am not sure if I understood what is corresponding command for PN5170. As I understood this IC should be configured to use protocol ISO DEP and Interface ISO DEP with RF_DISCOVER_MAP_CMD, and then it should be put into discovery mode with RF_DISCOVER_CMD. After that I can send data packets, and those commands that was previously handled by InDataExchange command should be put into payload. Did I got it right? Are there any libraries that demonstrate how to properly use ISO DEP protocol? I am still not sure whether I should use ISO DEP , NFC DEP or RF Frame protocols.

Hello,

According to Table 4 of PN7150's User Manual, PN7150-NCI supports ISO-DEP (Reader/Writer):

It would be helpful to refer to NCI pdf file available under registration in NFC Forum, which describes better the RF Communication Configuration.
