Introduction This document describes the message format of the communication protocol used by the host and the reader in order to issuing commands and reply with responses. The protocol is based on the Attribute Value Pair (AVP) schema and foresees a message header in order to identify the message scope. The command set and the firmware architecture draw inspiration from the Reader Protocol 1.0 specification draft from EPCGlobal but, at now, this protocol is not fully compatible with the same last specifications. Message fields are described left to right, with the most significant byte on the left and the least on the right. 1.1.

Protocol specification CAEN RFID UHF RFID Reader protocol uses two logical communication channels: one for synchronous commands and one for asynchronous notifications. Command channel is mandatory and, at now, it is implemented on top of a TCP/IP socket (port 1000) and on RS232 while notification channels are implemented only with sockets. All the messages (commands, responses and notifications) are composed by a header and a body. In all cases the body of the message is a list of attribute-value pairs. Responses always echo the Command AVP sent by the host. All the packets for the control and notification channel share a common header format: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ FIXED Message ID +-------------------------------+------------------------------+ Vendor ID +-------------------------------+------------------------------+ Length +-------------------------------+ FIXED: Must be 0x8001 for commands and 0x0001 for responses. Message ID: Id of the message. It is a sequence number used to map requests to its responses: a request and its corresponding response have the same message ID (the id is local to the channel). Vendor ID: Must be 21336: the IANA “SMI Network Management Private Enterprise Code” assigned to CAEN SpA. Length: Encodes the length of the message (in bytes) including the header. The header is followed by a list of AVPs the number of which depends on the command. Each AVP have the following format: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ RESERVED Length +-------------------------------+------------------------------+ Attribute Type Attribute Value ……… +-------------------------------+------------------------------+ ………[ until length is reached ]……… +--------------------------------------------------------------+ RESERVED: The first 16 bits are reserved for future extensions. All reserved bits must be set to 0 on outgoing messages and ignored on incoming messages. Length: Encodes the length of the AVP packet including the length and the reserved fields. Attribute type: A 2 byte code identifying the attribute type. Attribute value: The actual attribute value according to the type. It follows immediately after the Attribute Type field and runs for the remaining bytes indicated in the Length (i.e. Length minus 6 bytes of header).

Asynchronous Notification: Protocol specification The notification channels are implemented only with sockets. All the messages notifications are composed by a header and a body. In all cases the body of the message is a list of attribute-value pairs. The first AVP of the body is fixed and called NotifyMessage. All the packets for notification channel share the same header format of other packet as described at § 3. The first AVP (NotifyMessage) is followed by a list of AVPs, the number of which depends on how many tags should be notified. Each AVP has the same format of the AVP described in § 3. The NotifyMessage has the following fixed format: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ RESERVED +-------------------------------+------------------------------+ CommandName ReportBuffer +-------------------------------+------------------------------+ After the NotifyMessage AVP we can receive: a) a list of AVPs (as described in table 3) followed by an AVP with ‘Attribute Type’ ResultCode b) a single AVP called KillMessage with the following fixed format: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ RESERVED +-------------------------------+------------------------------+ KillCommand KillCommand +-------------------------------+------------------------------+ Table 3.1: Attribute types: Notification AVP List.
