Dear Yikai Chen
i didn't find any state machine diagram in that document.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

TI doesn't provide document that has state machine diagram for Z-Stack as I know. All the useful documents are under C:\Texas Instruments\Z-Stack Home 1.2.1\Documents

Dear YiKai Chen

Sir, which algorithm is used for the coexistence of IEEE 802.15.4/Zigbee AND WIFI.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

You can refer to chapter 4 of this document.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

If anybody use PREDICTIVE CHANNEL SCANNING AND SWITCHING ALGORITHM for zigbee channel scaninig.

Please refer this document once PCSS for zigbee.pdf

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

As I know, none of current Zigbee stack provider uses it.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

I don't know sir that's why i am asking you it is correct algorithm or not.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

According to my experience, it is just a paper that propose some fancy algorithm and impractical.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Dear YiKai Chen

Please refer this link and say about MAC scan duration table(Which is mentioned in link) is right or not.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

I read this book many time and I see no problem on it. What is your point?

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

Explain about MAC scan duration table and how he is define it.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

The scan duration is defined in Zigbee spec and is an integer between 0 and 14. The author of this book converts those times to milliseconds for your convenience.

Dear YiKai Chen

The CC2530 zigbee module is acting as a router. In case an interrupt is occur, then it execute the interrupt or not.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

No matter what role of CC2530 Zigbee module is, interrupt service would be executed when interrupt is occurred.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

Dear YiKai Chen
We are interface our CC2530 zigbee module with our controllerand our zigbee is acting as a router.
1.our controller sends a data packet to router at that time there is a packet come's from another router for route the packet to coordinator.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

Finally my question is which process is executed first routing process or data packet process.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

Sorry, I don't understand your question well. Can you be more specific?

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

there are two processes are comes for router to execute ,one process is comes from our external controller and another process is comes form other router for route the packet to coordinator at the same time. Now which process is executed first.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

This really depends on the use scenario. I would say who comes first and who will be served first if they all use interrupt.

Dear Yikai Chen
If router respond to the outside packet then what factors influence the application processor.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

According to my experience, router functionality won't affect application and you can't even feel it.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

is there any buffer overflow occurs?

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

I never see it.

Dear YiKai Chen

Zigbee routing will be performed on which layer.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

It supposes to be on ZDO and NWK.

Dear YiKai Chen

Zigbee data packet transmission is based on GTS concept or CSMA / CA concept.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

It is CSMA-CA.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

But why in packet sniffer those packets are showing GTS fields.

Please see the attachment

If we disable GTS field option but it showing why?

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

You can refer to Zigbee spec for GTS field.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

By the way, GTS here means Guaranteed Time Slot. I think it is different to what you mean in GTS vs CSMA-CA.

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

I mean GTS means coordinator allocate the every router packet to certain time slot and CSMA / CA means coexistence purpose.

What is the use of Random number generator and why it is?

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

What is your point and how is it related to Z-Stack?

0 Lakshmi Praveen over 10 years ago in reply to YiKai Chen

Expert 1410 points

CC2530 zigbee module generate a 16-bit random number.why it is and how it is used.

0 YiKai Chen over 10 years ago in reply to Lakshmi Praveen

Guru 735685 points

Random function is basic one in programming world. For example, it is used to generate PANID in Z-Stack.

Hi,

ZigBee networks are non-beacon. Non beacon means asynchronous, not that is it is not using the 'Beacon' type of frames. GTS is used in deployments where the 802.15.4 coordinator periodically emits beacon, and as mentioned this is not the case in ZigBee.

The frame format of the Beacon frame as standardized in IEEE 802.15.4 spec includes GTS field, but in the context of ZigBee all the fields are 0 which in fact means that the coordinator does not permit GTS requests and that there's no GTS descriptor allocation.

Hope this clarifies.

Thanks,

TheDarkSide

Dear YiKai Chen

In CC2530 module we are facing a reset problem.if any reset occurs module loosing its state then we send AF_REGISTER and APP REGISTER again it showing it's state, For overcome this problem We enable NV_RESTORE and HOLD_AUTO_START options in code and dump the .Hex file in to our module but we can;t find any solution and we facing same problem again.
