[Icc-avr] Atmel/Meshnetics Zigbee Stack

[John Edwards]

It wasn't my intention but maybe it's time to talk about what the most
accessable (cheap and easy) Zigbee solution is. I can see that for the
simplest sensor based application, layering your application on the Zigbee
processor makes sense. But any complex application would at least initially
have to have it's own processor.

So: I still want an ICCAVR based Zigbee stack. I hate all these little bits
of GCC code we have floating around. Any solutions out there??

BTW Meshnetics is targeting <$20 US for their module in medium quantities.
The original ZIgbee promise was <$5 and as you can see <$2 incremental cost
is happening
