Many of you who are trying to get your ZigBee product (Platform, Smart Energy, MSP or other) ready for certification might be confused with all the documents to read - the specifications, the appendices, errata, etc. All you want is to run the tests and make sure the behavior is what it’s expected to be before you go to get your product certified. In ZigBee, like in many other standards, the easiest way to do that is to emulate the Golden Unit (GU) behavior. They are, after all, the reference and they are what the tests run against so why not just do as they do?Unfortunately, the GU's might be a little hard to obtain. The manufacturers rarely give them out, and when they do, it’s usually at a pretty hefty price. Fear not! The Alliance has made available, through authorized test labs, the logs for those GUs. What does this mean to you? Well, now you can get these logs and just compare them to what you are observing on your own devices. Since the tests for ZigBee are conducted over the air, if you ensure that the behaviors are similar, your chances of success in certification will be pretty high. From there on, all that will be left to do is correct a few small glitches, if any, once you start your official certification testing.
