APPENDIX 2:

: RFID communication protocol

RFID communication protocol

Introduction

Generalities

Platform2 is supporting a communication interface with an RFID daughter board. Using a UART link,

the communication is possible thanks to a communication protocol described in this document.

Generic packet

All the frames described in this document are formatted as shown:

Code ID Length

Payload

1 Byte

2 Bytes N Bytes

Commands with codeIDs between 0x00 and 0x7F are configuration commands

Commands with codeIDs between 0x80 and 0xFF are communication commands

Communication protocol

Configuration messages

Code ID
