I have a question regarding the implementation of NFCIP-1 on Nokia 6212:
Does said Nokia phone implement to the letter the passive mode (phone is the initiator) from the NFCIP-1 spec?
The problem I have is as follows:
I have an NFCIP-1 device that can be read by the Nokia phone. Works great, no problems whatsoever.
Now I want to replace the phone with a PN512 chip connected to my PC. And everything goes fine, until I send the ATR_REQ command, which fails every time. I have no documentation for the NFCIP device, so I can't tell where's the problem. Although if I could send the frames in exactly the same way as the Nokia 6212, then this should work (as it works with the phone).
I know this is very low level, and most of you will suggest to upgrade to PN53x as it takes care of the whole anticollision stuff, but this is not an option for me. I need to go through the anticollision manually and with the PN512 chip as this is the only chip available to me.
Can anyone share some light on the subject?
