ST95HF. Application questions

I try to use chip ST95HF. I am a beginner in NFC. I need to develop Peer to Peer connection. What protocol should I use for it?

I can not see of the emitted field at 13,56 MHz.

I initialized of the chip to work for IEC14443B protocol (I checked of the reply – it was 0x0000). I used for test of the IDN command 0x000100 and received of the true reply - "NFC FS2JAST4".

Then I try to send of the test sequence:

0x00 0x06 0x64          0x35….0x35 (0x35 – 100 times).

I did not receive of the true reply (0x0C 0x00 instead of 0x00 0x00) and I did not see any field (I use a good receiver and tested of the SF95HF output by scope).

Could you help to understand of my error?
