E1067-00-002-01 Page 4 of 14 Command structure All data flow between the module and host is framed within packets. The packet structure is the same for data flow from the host as for data flow from the module and is shown below. HDR 0xFF Header, indicates the start of the packet LEN AA Length, number of bytes that are to follow as a part of this packet Data1 0xXX … … DataAA 0xXX Data bytes to be transferred. It consists of a defined (0xFF) header, a length byte which is the count of all data bytes that are to follow, and then all the data bytes themselves. Therefore if the data we wanted to send is 0x01, 0x02, 0x03, we would create the packet “0xFF, 0x03, 0x01, 0x02, 0x03”. For multi-byte transfers i.e two byte words, the low byte is transferred first. When transmitting a packet, the inter-byte delay must not exceed 500ms else this current packet will be abandoned and the complete packet must be resent. Currently the baud rate is fixed at 9600. Commands Scan for a single tag Returns the ID of a single tag, to be used when no more than one tag is in the field.

Setting GG to 0 and not sending any Data bytes will set the lock pointer to address FF.

Setting HH to 0 and not sending any Data bytes will set the lock pointer to address GG. When writing to an address less than 10 on a password protected tag, the module’s own internal confirmation will always fail regardless of whether or not the write was successful. This is because addresses less than 10 cannot be read on a password protected tag. It is down to the host application to check the required operation against the data returned from a Get tag’s configuration memory operation. Successful operation - data has been written and confirmed. HDR 0xFF LEN 0x02 CMD 0x0A OK 0x01 Unsuccessful operation HDR 0xFF LEN 0x02 CMD 0x0A ERR 0x0
