Now that you have introduced the ZigBee Stack functions well enough ... are there application level programs available for larger network applications where a PC can connect to the Network Coordinator to take data from the network from the coordinator, accumulate and organize and analyze network information as well as being able to know physical location of logical node ...
also for diagnostics (e.g. something similar to CAN_Alyzer if you are familiar with the CAN bus)
Again, since this is a review of the archived presentation, I will / am researching these issues ... but for possible inclusion or mention in future presentations it may help ...
Commissioning, Monitoring and Diagnostics are of interest now that the groundwork has been laid out in the first four presentations. It seems as if some capabilities or features might be difficult apart from the enhancements of ZigBee Pro.
I sympathize with the comment that this is too complicated for someone's app - it is in some cases. Over 80% of my designs have NOT been actual ZigBee. about 30% were not even 802.15.4 but used the phy and LL built into the silicon. Example, simple monitoring or control.
Anatoliy, you ask a great question. There is no one best answer. I have standardized to one mfr for new designs just to simplify what I have to stay current (and pay to maintain!) Being an old Moto guy, I use Freescale but also work in Microchip, TI, and Renesas. I teach my hands-on classes with Freescale.
The effective throughput through a router or coordinator does depend on the # of nodes. Picture a toll booth - takes longer to get through, even with an EZ-Pass, because everyone has to go through those few lanes
I guess my questions are for Friday: Can we get some insight about Zigbee vendors and their pros and cons? Also would be good to know about testing and debugging tools that associated with vendors or third parties and their pros and cons? What dev kits are recomended to learn Zigbee in more details?
Many nodes and modules can handle lots of great apps. DMX (I love working with that) is one case. voice over 802.15.4, sure. We have streamed low-resolution mp3s. If you have to, you have to. But like was said, you are hauling gravel with a Civic (actually, in my case, in the back of a Jeep Cherokee!)
78RPM: Voice over ZigBee is a misuse of the technology. Can you haul gravel with a Honda Civic? Yes, but it's not built for that. You'd be better off just using ZigBee to trigger pre-recorded messages that live on the end-node.
