Migrating from Thinkify HSP2_0 to HSP3_0 firmware

The 3.0 firmware command interface is similar, but not backwards compatible with the

interface used in the 2.0 system. Changes were made to add functionality, and improve

the usability and consistency of the command structure.

At the end of this document is a list of commands supported by the 3.0 system. Further

details of these commands will be described in additional documents.

Overall command entry -

In the 2.0 system several commands were redundantly provided both as PI level

commands and TR65 commands, but were actually just pass through commands to the

TR65 module. Then later on in the development of the 2.0 system it was determined there

was just too many commands to support this way of doing things, and the concept of

sending a command preceded by a '!' would result in a command directly sent to the

TR65.

The 3.0 system no longer supports this. For any command sent, the command interface

parser in the 3.0 will first determine if this command is meant to be processed by the PI.

If it is not recognized as a valid PI command it is then sent to the TR65. If the TR65

recognizes it as a valid command it executes it, otherwise reports UNKNOWN

COMMAND.

Therefore the whole concept of preceding the commands intended for the TR65 with a '!'

is eliminated. and the PI does not support any commands that are really direct TR65

control commands, but instead just directly sends these on to the TR65. Some examples

of the commands this applies to are setting the attenuation and radio parameters and

setting the trigger and delay parameters.

Data entry of programming data -

The development process in the 2.0 evolved as time went on. In the beginning only 96 bit

EPC programming was supported along with passwords. As development proceeded it

became apparent that further functionality was desired - examples being the size of the

EPC memory data field and the ability to program USER memory data. As these were

attempted to be added to the 2.0 command interface, the control structure got

cumbersome and difficult to use. There were multiple commands and setup procedures

depending on the desired actions to the tags currently being run which were unable to be

changed easily etc. The 3.0 system attempts to correct this.
