Temperature Measurement Attribute Reporting

Would you attach the sniffer log? It is hard to analyze from your snapshot.

Here it is:

Msg number 5 is ReportAttributes from Netwox temperature sensor and  status is OK. Message number 17 is ReportAttributes from Computime thermostat and status is Err.

I can't open your *.anl file type. Could you save it as *.psd?

.anl file can be opened with Perytons sniffer. Here is a .psd file captured with SmartRF Packet Sniffer which is very confusing for me and i hope you will be able to find what you are looking for.

EDIT: I converted the .psd file to .anl so msg number 9 is ReportAttributes from Netwox temperature sensore and message number 40 is from Computime thermostat.

@YiKai Chen

did you had a chance to take a look at the sniffer log?

P.S

Sorry if I am annoying but I have to figure this out and I ran out of ideas.

Sorry, I forget to have a look at your problem after weekend. I will try to have a check on your sniffer log tomorrow.

Ok thank you!

My latest assumption is that is has something to do with security. I'm using HA profile and security with default TC Link key is enabled.

It would seam I have found the root of the problem, which  I missed at first. My coordinator multifunctional endpoint ID is defined as 0x0C (12) and when I'm receiving AF_INCOMING_MSG from thermostat packages have DestEndPoint = 12, when I stop receiving AF_INCOMING_MSG thermostat starts sending packages with DestEndPoint = 10.

Any idea why would the thermostat device start sending packages with different DestEndPoint value all of the sudden?

Do  you do a thorough search of your source code if thes are keyword 0xA, 0x0A, or 10? I believe you must put endpoint=10 somewhere.

The only time I'm using my endpointIDis when I'm sending AF_DATA_REQUEST with source endpointID = 0x0C to send Configure Reporting Command to thermostat.

Anyhow if I where to change it somewhere in side my code then the temperature meter from Netwox would also at some point start to send AttributeReport with different endpointID and that dose not happen.

So there must be a link between the fact that the package from thermostat has an status: err and the fact that it starts to send AttributeReport with different endpointID.

Perytons sniffer says that the status Err is because off: "End of  message found in ProfileCmdAttributeId field".

Have you had a chance to look at my log?

Yes, I have checked your sniffer and I see that the latest Temperature Measurement report attribute uses 0xA as its end point. This is strange if you don't change it in your code. Is it possible that the memory of destination endpoint is overwritten by accident? Can you attach your source code for me to have a look?

Well I don't know since I do not have the source code from that device. Is there any setting that I am missing that could cause this type of behavior that comes to your mind?

Also I was thinking that since I only have one endpoint (multifunctional) registrated on my CC2530 I could hack up/hardcode Zstack to send all msg to my endpoint?

If you don't have the source code of temperature sensor, you should contact who provides you the device for help.

HI,

I also have to do something similar as what you have done.

"I have a zigbee devices (thermostat) that has temperature measurement cluster and I set periodic attribute reporting via configure reporting command. When this device sends ReportAttributes it is passed to me over UART with AF_INCOMING_MSG and I can process it and get measured value."

So I have a z-stack running on my cc2530. I have a temperature sensor which is getting paired with cc2530. I want to retrieve the data which temperature sensor is sending to cc2530 and then pass it over UART.

Can you please guide me in this.

Thanks,

Nilima

Hi Nilima,

Since this is an old thread, I suggest you open a new thread in case the issue persists.

- Install z-stack HA 1.2: http://www.ti.com/tool/z-stack. It consists of HA1.2 compliant sample apps, including separate apps for temperature sensor , thermostat and heating cooling unit. Please read the sample app users guide - installed as part of HA1.2 package.

- Open sample app project (ex: thermostat)  in IAR and open file hal_uart.c . It has h/w UART interface details. Checkout uart init, read and write functions - search for usage of these functions in the opened project ( ex: file MT_UART.c). This should give you a good idea of how to use UART.

Thanks,

Saurabh

Hi Nilima,

Have you already receive temperature attribute on your ZC? And you just want to send temperature to UART?

Thanks for replying to my query.

I have CC2530 which is acting as SampleThermostat co-ordinator. I have a sensor which is getting paired with CC2530.

Sensor is using following cluster:

TEMPERATURE_MEASUREMENT

My AIM is to send temperature measurement to UART.

But I dont see temperature attribute coming on ZC.

Is there anything we have to do in SampleThermostat application to see the actual temperature data?

Hi Nilima,

Would you please specify how you send your temperature to coordinator? Do you use correct destination address and end point?

Hi YiKai

7875.Frame_dataformat_TH.pdf

The above file contains the data format what sensors are sending to my co-ordinator.

Also I can debug upto "afIncomingData()" in AF.c that I am receiving some packets after pairing is done.

Please find below packet sniffer data

0385.sensor_packet.psd

I have problem open your sniffer log. After I read 7875.Frame_5F00_dataformat_5F00_TH.pdf, I see those commands seem not provide by TI. Where is your temperature sensor from?

Which command?

Also I have question.

SampleThermostat does binding on the key press.

But I dont have any such keys on my device. So How can I handle binding?

In Frame_5F00_dataformat_5F00_TH.pdf, there is command like "41 54 2B 1E 91 00 12 4B 00 01 17 C5 BA AD A0 02 0A 04 02 01 04 40 18 47 0A 00 00 29 64 0D FD". As I know, it is nothing like TI's command.

You can use ZDP_BindReq from ZC to do binding.

Exactly at what location I need to call ZDP_BindReq?

Once you have enough information (simple description, IEEE address, active endpoint,...) of binding devices, you can use ZDP_BindReq anywhere you want to trigger binding.

So suppose If I dont have binding done, Then I wont be able to receive any data from temperature sensor.

Sorry for troubling you a lot.

Yes, you won't receive any data if you don't do binding. Binding is used to tell device where to send data.

Thanks YiKai for your support.

Does the co-ordinator will send the bind request or the sensor has to send the bind request,

Because in one of the document I have read that co-ordinator  will receive the bind request.

If you use ZDP_EndDeviceBindReq to do binding, it needs to be sent from two binding devices and coordinator will receive the request and coordinate binding. If using ZDP_BindReq, you can sent it from coordinator directly.

Hi YiKai,

Following are few my queries. Sorry for posting all together.

I am still not able to receive the temperature measurment in thermostat application.

There is no binding done in the sensors we have received. We are using NHR S05-ST sensors.

Can you tell me APS layer function where I will get data received indication.

Also when "Data Request" packet will be sent? whether co-ordinator will send this packet or end-device(which is sensor in this case).

Also my sensor is getting paired with the coordinator when coordinator is non-beacon mode. In beacon mode sensor is not getting paired.

Nilima,

I don't have experience doing integration to NHR S05-ST sensor. I need more information to help you. I think you need to do the following steps and use packet sniffer to keep over the air messages for debug.

1. Start a coordinator to form Zigbee network and enable permit join of this ZIgbee network.

2. Start NHR S05-ST to send beacon to join coordinator.

3. Make sure NHR S05-ST joins your coordinator in packet sniffer.

4. Trigger ZDP_BindReq to bind NHR S05-ST with coordinator.

5. Check if NHR S05-ST sends temperature correctly.

p.s. I would suggest you use ubiqua protocol analyzer to do packet sniffer.

Please find below the packet capture using ubiqua protocol analyzer.

You can go to Tools->Options->Security and add the key "0x5A 0x69 0x67 0x42 0x65 0x65 0x41 0x6C 0x6C 0x69 0x61 0x6E 0x63 0x65 0x30 0x39" into list.

Thanks a lot.

Yes I did that and I am able to see Temperature Measurement at ZCL layer in the packet capture.

But in the code, in zcl.c, which function will get hit. How do I see this data in the z-stack code.

In my case I can see afIncomingData() function is getting hit. And I think I am able to get encrypted APS payload.

If we use SampleSwitch project as coordinator, you should process it in zclSampleSw_ProcessIncomingMsg. In zclSampleSw_ProcessIncomingMsg, there is case ZCL_CMD_REPORT: and it calls zclSampleSw_ProcessInReportCmd. You can implement processing in zclSampleSw_ProcessInReportCmd().

I am using sampleThermostat as Coordinator.

But I dont see zclSampleThermostat_ProcessIncomingMsg() getting invoked.

Set a breakpoint at zcl_ProcessMessageMSG in zcl_event_loop() and make sure it stop here first.

No it is not stopping in zcl_event_loop when data transfer is happening.

Since it will hit afIncomingData, you can trace into it and see why it doesn't go to afBuildMSGIncoming.

Thanks a lot YiKai.

Was able to solve the problem. The endpoints defined on coordinator and sensor were different.

Hi Nilima,

Great. It's nice to hear that you make it work.

Can you tell me exact function in z-stack where we get to know the end-point is successfully paired with co-ordinator and we can get information of end-point like its short address etc.

Hi Nilima,

You can use ZDP_ActiveEPReq to ask for endpoint of end device.

Yes but my application needs to know when the sensor successfully joins the coordinator.

When end device joins ZBS network, it will send end node announcement. You can receive it in coordinator which allow s you know end device joins coordinator.

Hi YiKai,

I am done with the end node announcement.

Now I want to figure out how coordinator comes to know when any of its end-device gets disconnected. Can you please provide inputs on this.

Thanks & Regards,

Nilima

Hi Nilima,

There is no callback or event to know device disconnected from it. The alternative is your application implements supervision message sent to coordinator periodically. If coordinator doesn't receive the supervision message, it means device loses connection.
