CCS/DLP-7970ABP: NDEF Message reading and writing from NFC enabled smart phone

Part Number:DLP-7970ABP

Tool/software: Code Composer Studio

Hi,

I want to send NDEF message to have a Peer to Peer communication with Android mobile (without any type of tag). 

I have a few questions in the example code provided for DLP7970ABP + CC3200 launchpad for NFC reader operation:

1. What is the purpose of the file NDEF.C ?
2. Can I know the functionality in detail for the following functions and how to use them in sending and receiving (reading and writing) the NDEF messages.

   void RATS(void);
   unsigned char NDEFApplicationSelect(void);
   void CapabilityContainerSelect(void);
   unsigned char ReadBinary(unsigned char Offset, unsigned char Read_Length);
   unsigned char ReadBinary2(unsigned char Offset, unsigned char Read_Length);
   void SelectNDEF(void);

   And can anyone tell me the basic setup details for performing the Peer to Peer communication between with  DLP7970ABP + CC3200 and Android mobile?

   On a whole I want to have a Peer to Peer communication without any type of external passive tag, so can anyone suggest the good approach for the having the  Peer to Peer communication with  DLP7970ABP + CC3200 and Android mobile.
