[Radioactive-design] RE: HW Emulator: feedback

[Vadim P. <vpe...@ho...>]

I read through your HW Emulator list. It is pretty old, but here is some =
feedback anyway:

Simulating reader protocols is a very time consuming task. I have done =
not for most readers, but I could justify it because I need to test =
device drivers. Documentation for reader protocols usually comes with =
the readers and one cannot download it from HW vendor web site. This =
really means that creating and maintaining HW simulators will require =
buying reader or probably requesting a loaner from manufacturer.

If purpose of creating HW emulator is to test middleware, I would opt =
for creating a simple protocol and use it for simulation.=20

As far as RAReader interface is concerned, it is a pretty good shot. =
However there are a few things to consider:

* Readers have 1-N antennas and some configuration attributes are =
related to antennas. setReaderProperties() can only deal with device =
configuration, but not antenna configuration. One solution is to have =
Antenna[] getAntennas() and setAntennaProperties( Antenna ant )
* Status notification is a well-defined function can be represented =
through a listener interface, without Savant EMS messaging.Status =
notification is needed to for monitoring purpose, for other application =
entities to react to status (e.g. a workflow that handles a production =
line, etc.), or to initiate device recovery process. All of these =
aspects can be encapsulated in a framework and exposed through facade =
interfaces.

Thanks.
