Sending data problem

Mehek Rai

Other Parts Discussed in Thread: Z-STACK

I configured the sample switch as Coordinator and sample light as End device. I am trying to send a message from Coordinator to End device. End device is joining to network and sending data request continuously. But if Coordinator is not able to send a data to End device. It is trying to send 8 times. But End device is not receiving it and acknowledging to Coordinator. But the same sample light code configured for Router, Router able to receive the data and sending the acknowledgement. I have a log result.psd

From the sniffer log, it seems send some basic command in wrong format so ZED can't recognize it and don't response to it.

But if i configured as router with same code without changing any thing . It is receiving the data. Is there any different to be send for End device and Router

NO, it should be the same. I don't see ZC send command to ZR in your attached sniffer log. How do you know your ZR receives data?

i didn't attached the log for ZR. But same device i configured as ZR. It is receiving the data and blinking the LED also

Can you attach the sniffer log with ZR? By the way, what command do you send from ZC to ZR or ZED?

Router.psdI used AF_DataRequest(&dstAddr, &srcEP, ZCL_CLUSTER_ID_GEN_BASIC, strlen((char const*)buffer), buffer, (uint8*)TRANS_ID, AF_SKIP_ROUTING, AF_DEFAULT_RADIUS );

The problem is what inside your "buffer"? I think your buffer doesn't follow ZCL payload.

what is ZCL payload? i am sending "TOGGLE\r\f"

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Guru 735695 points

Since you use ZCL_CLUSTER_ID_GEN_BASIC in AF_DataRequest, you have to following ZCL payload for Basic cluster. You can refer to ZCL spec for details.

Please can you give the refrence where it is. Depends on Clusture id buffer format should vary? Can't we directly send the buffer string

0 YiKai Chen over 11 years ago in reply to Mehek Rai

1. You can refer to ZIGBEE CLUSTER LIBRARY SPECIFICATION.

2. If you use Zigbee HA profile, you have to follow HA profile/ZCL spec and you can't send buffer string directly.

I could not able to find how should be the format of buffer.(Can you please give one example as per above cluster), iam using Zstack Home 1.2.1. If this is the case, then why router only receiving the that same buffer data why end device not

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Guru 735695 points

If you intend to send a buffer, you should refer to GenericApp in Z-Stack Mesh.

0 Mehek Rai over 11 years ago in reply to YiKai Chen

In that also it is using same thing, instead of "TOGGLE\r\n", "HELLO WORLD" and using GENERICAPP_CLUSTERID. In that buffer the raw HELLO WORLD is there

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Guru 735695 points

It is different. GenericApp doesn't use HA profile and ZCL so raw data buffer won't be filter by ZCL layer.

Mr.Chen i am confused, you only told me to refer GenericApp. So i did.
-> Please can you tell at least one example to send. If i want to Send TOGGLE using HA Profile what should in the sending buffer.
-> If that command itself wrong, then how router able to receive and End device not

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Guru 735695 points

When you say that you want to send TOGGLE using HA profile, do you mean to send a toggle command to a light or something? Or you really want to send string "TOGGLE"?

I want to send a string

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Guru 735695 points

If you want to send a string, GenericApp is definitely a best example for you.

Mr Chen, i have used already AF_Data request using Zstack 2.5.1a. But now i am using Zstack Home 1.2.1. I used AF_Data Request as same as GenericApp only difference is i am using HA profile and different Clustur Id. As you see in the sniffer, it is sending data but end device is not responding and Router is responding. I am not getting where i am doing wrong

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Can you show me how you receive sending data on your end device?

0 Mehek Rai over 11 years ago in reply to YiKai Chen

Prodigy 130 points

You are asking about 2.5.1a?. I can able to receive in zcl.c. I have shared sniffer log of Zstack Home. In 2.5.1a i didn't get any problem of AF_DataRequest. I want to tell one more thing. AF_DataRequest is working from End device to Coordinator but not from other way round in Zstack Home 1.2.1

0 YiKai Chen over 11 years ago in reply to Mehek Rai

Since you can't receive data in Z-Stack home 1.2.1, can you show me how you receive data in it?
