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.

Glad that the lectures can be kept to less than an hour ... and very glad that these are archived lectures -- very helpful to be able to stop, research, review ...

z-wave is very economical and does not require high skill level...

Iron

Wow... the original plan was to make this lecture shorter than the previous few... information overload... :)

Iron

One more lecture to go in this track...

Iron

Great to have access to the recorded sessions!

Iron

Back to the offline lecture...

Iron

I also had problems following the lecture. I sometimes got lost with the slides.

I prefer when the speaker clearly indicates which slide is next

Iron
Hello
Catching up again
Iron

I agree Frank, I had trouble following along with the slides as well. 

Alot of good information here

had problems following the lecture in the begining

I prefer when the speaker makes comments on the slide number often

Thanks Charles for sharing knowledge

Iron

Boy am I ever getting lost, those slide numbers.

I shall study up and make out soon. Rod. R.

Iron

Thank you and look forward to more.

Iron

Thanks all for attending!!! Your feedback is very helpful!  Join us tomorrow as we wrap up this week.  Thanks to Rob and Design News and Digi-Key for making these happen.  See you tomorrow!!!

Iron

I will try to cover XBee in modules tomorrow.

Iron

I only use the brands I listed simply as one cannot be an expert (and afford tools for) active development in every mfr's chips.

Iron

Perhaps my last post was lost in the ether - Atmel would be a fine choice.  All have their strengths and weaknesses. Depends on your app

Iron

Can I use both XBee Pro900 and XBee Pro Series 2B in the same network?

Iron

All nodes on a network stay on one channel at a time

Iron

Would you not recomment Atmel ZigBee chips?

Iron

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.

Iron

Can the endpoints share the same channel?

Iron

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.

Iron

Thank you. See you tomorrow.

Iron

Thank you Charles for good sessions!

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

Iron

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!)

Iron

Thanks for the lecture;

 

Iron

Does it means the throughput of coordinator depend on how many node (endpoint)?

Iron

Yes, an end point can be part of multiple profiles.  But there are caveats. and tradeoffs.

Iron

That was a ton of information. Thanks so much, Charles.

Blogger

OK! Coffee in hand - First to JSP - the coordinator throughput is much closer to the full 250kbps, but with all of the nodes speaking, a single node may only see 20-30kbps.

 

Iron

thanks Charles and Rob. Enjoyed very much.

Can we do Voice over ZigBee if the message is very brief -- e.g., "Press OK to start."  Or is that best handed off to another device using a switch activation?

Gold

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.

Iron

Using this hardware.

Iron

Thanks Charles, Ron and Digikey Design news!

Iron
Thanks Charles for an excellent presentation.

Thank you all and a Merry Christmas and Happy New Year!

 

Iron

Thanks Charles and Rob. Thanks your good info!

Can ypu recommend some RFD device set for me and their website. Thanks a lot.

Iron

Thanks all - sorry for running long but there was a LOT to talk about!  I will be back in 30 seconds to answer questions!

 

Iron

Thank you!  Great information!  Another session with examples would be absolutely terrific!

Iron

Charles, thank you for today's lecture

Iron

Charles, have you had any experience with continual sensor transmission using 15.4 or ZigBee ?

 

Iron

Thank you Charles and Rob.

Iron

Thank you all, gentleman.

Thanks Charles, informative presentation.

Iron

Thanks.  Another interesting lesson.

Iron

Thank you Charles. 

If ZigBee is too complicated for my product, are there alternative protocols suites for 802.11.4? Are any of these standards?

Iron

Good info, thanks a lot

Iron

Thanks very much Charles & Rob; Excellent info! 

Iron

Good - thks Charles, Rob & Digi

Iron

Texas Instruments

and yes am interested in light connections as well

Iron

We're now on slide 17.

Can we do Voice over ZigBee if the message is very brief, e.g., "Press OK."?

Gold

We're now on slide 16.

Blogger

We're now on slide 15.

Blogger

Is ZigBee ONLY IPv6? (as opposed ot IPv4)

Iron

We're now on slide 14. 

Blogger

(that would be AN xBee...)   :)

(Actually, a xBee can do 512 channels of DMX without blinking an eye!)

We're now on slide 13.

Blogger

sorry, more than one application spec at the same time?

Iron

can a network support more than one protocol at the same time?

Iron

thank you for a good info

Iron

Thanks Charles and Rob.

Iron

Yes, I would be very interested in a webinar covering a practical example.

@Rob & @Charles  - ZigBee 2 Design Session would make a great addition to the series.

Iron

Wow, it would be great to see real examples! 

Iron

Is the co-ordinator aggregate throughput limited to 20-35kbps ?

Iron

audio just died here when the other phone rang

Iron

We're now on slide seven.

Blogger

Can a given end device be a member of 2 different networks at the same time?

Iron

If the audio is not working after you refresh your browser, you can play the program back after it's archived. It ill be archived as soon as the audio program is finished.

Blogger

yes refreshing my browser worked for me

Iron

We're now on slide six.

Good afternoon everyone

Iron

TonyD, what is the reason you care about its uncertain latency?

Iron

Hello from US East Coast.

Iron

Good morning from SoCal

Iron

@JoeFromOzarks, Yeah, that's the knid of mrning we had here, too.

What I like about Zigbee is its mesh networking. What I don't like is its uncertain latency.

Iron

Wind here is driving everyone crazy.  50mph gusts.   I always wanted animated outdoor Christmas decorations but this isn't quite what I had in mind!   :)

morning, now did did post.

Iron

Hey, this does not want to post today. ???
