I think the best analogy here are software patents. AFAIK, nothing 
prevents YOU from writing GPL code, that relies on patented
technology, but end user of the code may get into trouble by using
your code in commercial application - regardless of how well
he adheres to the GPL.

Same applies here: you are (I assume) not working for profit, and
therefore you are free to work on ZigBee. If, on the other hand
your GPLed code ends in someone's product, he will be in breach
of the ZigBee license, even if he does everything what GPL
demands from him. This way, your code is essentially non-free.

I don't know exactly how patents are handled in GPL V3 (and assume
they are not at all in V2) - if using patented technology is
considered a breach of GPL (since it may make code non-free),
then the use of ZigBee specs has the same effect.

And, standard disclaimers apply: I am not the layer and this is
purely my opinion, not advice.
