Good presentatons. Thank you Fred.

Iron

Thank you Fred and Lauren!

MiWi seems a good platform for many applications

Not familiar with the RN-XV

This made building wireless networks seem very easy.  I'll have to give it a try.

Iron

See you all next seminar

it was really fast but great!

Iron

I had a blast this week and I hope you did too!

Blogger

Did I answer everyone's question?

Blogger

@FrankMcCarthy

Take another look at slide 16.  You will see that I distinctly specified 8 octets as the additional node ID.

AdditionalNodeID[0] is assigned the value of the third octet of the 64-bit address (0x21).

I think it has legs :-)

Blogger

Hi Fred, Is this the issue. In the command payload, the node capacity is stated as 0x21 which should have been part of the 8 octets in the Additional Node ID. 

There is a one byte offset in the field.

 

@xynxnex

It can be any node capable of being configured for indirect messaging.

Recall, RFD nodes can only talk to a coordinator.

Blogger

Thanks Fred. The message forwarding node sounds pretty slick.  Thanks for a great series.

Iron

? is the message forwarding node then part of the pan coordinator?

Iron

Did I miss anyone?

 

Blogger

Thank You Lauren, Design News and Digi-Key.

Iron

Fred -  Thanks again for sharing your expertise. I always enjoy your presentations. I'm looking forward to doing some experimenting with MiWi.

Iron

@garysxt

MiWi has the option to configure a message forwarding node.  The message intended for a sleeping node is captured and stored by the message forwarding node.  When the sleeping node wakes up, it polls the message forwarding node for any missed messages.

Blogger

@FrankMcCarthy

The 0x21 is part of the 8 additional Node ID bytes.  It is not a bit field.

21 16 AB are the first 3 octects of the 64-bit EUI.  CORD 0x20 makes up 5 more octets of the additional Node ID.

That's 8 octets in total as was configured.  The sniffer should not have broken down 0x21 as a bit field as it is part of the EUI I included for application ID purposes.

Blogger

? can you explain the 21 bug from page 16 ?

Iron

I now have a basic understanding of MiWi and some of the tools available for working with MiWi. Its not so scary after all. Will consider MiWi for future projects.

Iron

@Ferrero

Microchip's 8-bit Wireless Development Kit.

Blogger

@chsengineer

It's a free download from Microchip.

Blogger

@xynxnex

The modulation schemes can be similar.  So, that's why I chose channel 26 for the 802.15.4 PAN and chennel 6 for the WiFi device.

Blogger

Thanks so much 78RPM

Iron

I was not familiar with the RN-XV (until today that is...)

Iron

@Ferrero, I'm sure Fred will have a suggestion, too.  You can find his class on ZigBee in the CEC archive. I purchased a book that helped me: Building Wireless Sensor Networks bu Rpbert Faludi. Chapter 1 gives you a shopping list. Chapter 2 has you doing your first application. Then it's on to sensors and feedback.  Amazon lets you read a lot of this book in the "Look inside this book" link.

Platinum

@Fred

Okay, thanks!  I was getting confused about whether you were suggesting some kind of ISR or multi-threaded solution :)

Iron

@N3WWN

The code I expose is sometimes taken from differing threads.  It's bits and pieces and is not really intended to be interpreted as a single program.  The idea is to convey the concept.

Blogger

Presently no need to monitor a remote 802.15.4 network, but sounds useful.

Iron

Here is a search which shows a bunch of those modules: Some as cheap as ~ $25

http://www.digikey.ca/product-search/en/rf-if-and-rfid/rf-evaluation-and-development-kits-boards/3539644?k=MRF24J40

for those who want some variety in their RF life.

SO even if you do need a MicroChip module -- the price is right.

Iron

?? Fred, do you have implementation suggestions for MiWi if you want the nodes to be battery powered and have long life, but need fairly quick response to commands from the controller? Normally you would turn off the receiver and just listen from time to time, but then you might miss a command from the controller.

Iron

Thank you Fred, Lauren and Digi-Key, have a great weekend!

Iron

Back from my meeting, catching up...

Iron

?? Fred, on slide 16, you said that the 21 in the payload was a bug. Why is this a bug? The last three octets of the address are 0x21, 0x16, 0xAB. 

Thank you Fred and Lauren for the seminars.

Adding the WIFI to MIWI in todays session was a great way to tie it all together

Thanks a lot Fred and Lauren!

Iron

Excellent presentation!!

 

I haven´t experience with ZigBee. What board should you advise to buy in order to start with ZigBee?

Thanks so much.

Iron

Thanks Fred and Lauren 

Iron

?? can the WDS be downloaded from Microchip or can you get it only from a purchasing a dev kit?

why dont the mifi and wifi interfere with each other?

Iron

Thank you Fred & Lauren

Iron

Thanks Fred, Lauren and Digi-Key.

Iron

Thanks again for this series on MiWi!  More MiWi, please!

Iron

Great presentation, Thank a lot Fred

Iron

Thanks for the great series on MiWi/802.15.4

Iron

Thanks Fred, Lauren & Digikey.

Iron

Awesome Fred, than you for the series.

Thank you Lauren and Design News

Thank you Digi-Key

Iron

Thank you, Fred and Lauren.

Iron

Thank you Fred, Lauren and Digi-Key

Platinum

Thanks Fred, nice info this week

We are on slide 21. 

Platinum

Looks like something to keep in considertion for future projects.

Iron

MiWi would be a good choice for many applications that can be  closed system.

Iron

MiWi look like a possible choice for wireless needs.

I like MiWi, try to use it

Iron

Seems to make setting up a wireless network easy

Iron

I might consider it for future use.

Iron

Looks better - will consider for future use......

 

 

Iron

I might be able to use

Iron

I really like MiWi!

Iron

MiWi definitely a choice should I need to do wireless. thx

 

Iron

It might be viable the next time I have an application.

Iron

The question was: How do you feel about MiWi? 

Platinum

The coord and node now both have multiple do { ... } while(1); loops... that's not possible, is it?

Iron

We are on slide 13. 

Platinum

We are on slide 12. 

Platinum

How can we have two do{...}while(1); loops?

Don't currently have a need.  Who knows about tomorrow though.  :)

Iron

No remote monitoring requirements at present

 

Iron

might need to monitor one in the future

 

Greetings from Bremen/Germany

Iron

The question was: Do you have a need to monitor a remote 802.15.4 network?

Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.

@78RPM  Yes, been reading Fred's magazine articles for years.  I even have an EPROM emulator he used to sell way back when.

Iron

Fred, since your previous class I've been enjoying your column in Nuts & Volts.  I think I'll subscribe to Servo, too.

Platinum

Good plan to split the narrarative across slides 19 and 20 - that's what I'd do!  TGIF.  ;)

Yep.. Duplicate slidss 19 and 20..

I really wanted you to get the idea behind the  RN-XV :-)

I'll only talk about half of what I wanted to say on slide 19 and spout out the rest on slide 20 :0

Unfortunately, I have a meeting conflict today. Downloading the slide deck now. Will review, but will have to catch up on the lecture later on today.

Have another great session everyone!

Good morning from Beaverton, Oregon

Iron

The streaming audio player will appear on this web page when the show starts at 2 PM Eastern time today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. If that doesn't work, the class will be archived immediately following our live taping.

Platinum

Be sure to click 'Today's Slide Deck' under Special Educational Materials above right to download the PowerPoint for today's session.
