Sorry for the delay in y reply but O have been travelling for the past couple of weeks.

I suspect that this socket is not available any more as it is quite old and I know they no longer market this model. I imagine the problem is caused by something this device is doing which may not be conforming to the Zigbee specification. whilst the Nordic nRF52840 should indeed survive this it is difficult to justify the effort required to resolve the issue if it is truly unique to my situation. I have removed the device from my network and have not encountered any further problems as yet.

If you would like to pursue the problem further I would be happy to send you the offending device for your developers to test with. Just let me know who and where to send it to and I will ship it to you for testing. I really do appreciate your help and the responsiveness of your support which confirms that the nRF52840 was the correct choice for my development.

Is it possible to obtain this "older Zigbee power socket from SmartThings" in order to reproduce the issue? Do you have a model/version number?

Could you provide zigbee stack trace and wireshark log when this device connects to the network?

RE: Zigbee Light Demo stops responding

I believe I have isolated the device that is causing the nRF52840 to fall over. It is an older Zigbee power socket from SmartThings. In the WireShark trace it is at source address of 0xa1d5. With that device out of th enetwork the nRF52840 worked for 24 hours but once it was reintroduced tot he network the nRF52840 fell over within a few minutes.

I moved the nRF52840DK to my other environment which has an identical hub and it has been working for 24 hours without issue. This leads me to suspect some other device in the network is upsetting the ZBoss stack. I will move it back and run some tests by removing other Zigbee devices to try and nail down what is causing the failure. I will report back as I make progress. Thanks again for your help.

RE: Zigbee Light Demo stops responding

I have two SmartThings hubs in my environment in separate buildings. I will try the Nordic 52840DK in the second environment to see if it is truly the hub that is causing this or if it is some other device in the network. I will also try and grab a WireShark trace. It would be great if we could get some sort of time stamp on the debug log trace so we might be a ble to match it to the WireShark trace. Do you know if this is possible in Segger? My hubs are both Samsung SmartThings V2 hubs. I can provide access to my SmartThings account so you can see exactly what is in the network. I will need an email address to set up an account.

RE: Zigbee Light Demo stops responding

Jørgen Holmefjord — Fri, 26 Apr 2019 10:43:50 GMT

Our developers have analyzed the logs you provided, and confirm that the Zigbee stack is asserting. They know where the assert was called, but still don't know why it asserts. They have tried to reproduce the issue without success, and will now acquire SmartThings hub V2 to test with.

In the meantime, it would be of great help if you could provide information on the following points:

Please provide as much details about the hub as you can collect (the hub name, version, revision, if possible to get also it's firmware version).
Please provide as much information as possible about other devices in your zigbee network (do you have other routers or end devices, except light bulb demo and light switch demo?).
Can you perform the test again and gather logs (this binary dump with <info> zboss: is perfect) AND wireshark logs from the same test run? Having both will help us correlate logs with network traffic.

RE: Zigbee Light Demo stops responding

Jørgen Holmefjord — Tue, 23 Apr 2019 15:15:18 GMT

I have forwarded your findings to the developers. They have started investigating and trying to reproduce the issue.

RE: Zigbee Light Demo stops responding

I downloaded the new SDK and tried to recompile my code. Since there appear to be many changes to the SDK and no apparent documentation explaining what must be done to existing projects to allow them to use the new 3.0 SDK I decided to simply start again with the 3.0 demo light bulb code.

I added the necessary bis to the Segger project to allow RTT log output. I am still amazed that you ship examples without this enabled! I then added all the logging stuff. I wasnt sure how to go about changing the library to the debug version so I simply replaced the two standard files with the debug versions indicated in your last post.

I changed the default Zigbee channel mask to ZB_TRANSCEIVER_ALL_CHANNELS_MASK and added code to reset the persistent storage if the ON button is pressed on startup, This second piece should be added to the examples with a note explaining what it does. You should also make the network connection light blink when it is waiting to connect but I did not do this so I could keep as close to your original code as possible.

The program failed after only a few minutes in the same way as before.

I did not capture a new WireShark log but the old one is still on my WEB site and nothing has changed in the environment. I place a ZIP copy of the entire project and a text file with the output of the debug window. These are available at http://www.cedartechnology.com/Nordic.

RE: Zigbee Light Demo stops responding

Jørgen Holmefjord — Tue, 09 Apr 2019 10:29:49 GMT

I just got some feedback from our developers:

Unfortunately provided zigbee_stack_trace.log does not contain any useful information. The problem is complex and hard to reproduce. However nRF5 SDK for Thread and Zigbee 3.0.0 have been made available today. This release include a lot of bug fixes.

We advise to the customer to do the following:

build the application with the new version of the SDK
- If the problem occurs again (we hope it won't), recompile the application with zigbee library traces:
  - use trace-enabled libraries, you will find them in $(SDK_ROOT)/sdk/nrf5/external/zboss/lib/debug
  - enable the tracing by setting in application's sdk_config.h the following:
    - ZIGBEE_TRACE_LEVEL 4
    - ZIGBEE_TRACE_MASK 0xFFFF
    - NRF_LOG_DEFAULT_LEVEL 4
    - NRF_LOG_BUFSIZE 65536
    - NRF_LOG_MSGPOOL_ELEMENT_COUNT 32
    - NRF_LOG_MSGPOOL_ELEMENT_SIZE 40
    - NRF_LOG_BACKEND_RTT_TX_RETRY_CNT 100
    - SEGGER_RTT_CONFIG_BUFFER_SIZE_UP 32768
  - Please provide source code of the application (if possible, the link http://www.cedartechnology.com/Nordic/light_bulb.zip is dead), wireshark log (or other pcap compatible) and traces.

Jørgen Holmefjord — Tue, 02 Apr 2019 14:36:16 GMT

Unfortunately, I have not heard back from the developers yet. They are quite busy, but I have requested an update as soon as possible. Sorry for the inconvenience.

RE: Zigbee Light Demo stops responding

IanAber — Fri, 29 Mar 2019 23:53:34 GMT

Is there any news from development? Is there anything I can do to help? It seems like a buffer management issue since it invariably stops around the allocation or deallocation of a ZBoss buffer.

I really like the Nordic environment and the nRF52840 but I am coming under a lot of pressure to look at alternative devices from other manufacturers if I can't get this to work. All I am trying to do is to get a stable platform running in a commercially available mix of Zigbee products so I can develop five different devices to monitor and control an off grid power and air conditioning system. I have some of the code working but I can't keep the nRF52840 connected for more than a hour or so which means it is all pretty useless.

RE: Zigbee Light Demo stops responding

Jørgen Holmefjord — Mon, 25 Mar 2019 10:15:18 GMT

Yes, I was able to read the sniffer trace using the keys. I have forwarded the details to our developers, hopefully they can shed some more light on what is happening from the sniffer trace and stack logs.

RE: Zigbee Light Demo stops responding

IanAber — Sun, 24 Mar 2019 14:47:17 GMT

Did the keys work for you? I have been trying to do more checking myself. When I run the code on the nRF52840DK I can see that most of the time it stops in the zb_nrf52840_abort function sitting in an endless loop flushing the zb_osif_serial buffer, which is of course empty.

The stack trace shows only back to the zb_free_buf() function (1 level up) so I cannot tell where it came to from that. Is there any more I can do to enable me to help find out where it is going wrong?

RE: Zigbee Light Demo stops responding

IanAber — Fri, 22 Mar 2019 14:05:20 GMT

Sorry about that. I did not realise the trace would not have been decrypted already. To save time, here are the keys my system is using to read this data...

Transport Key : 5A 69 67 42 65 65 41 6C 6C 69 61 6E 63 65 30 39

Network Key : 50dcaba83f417592833406696ed2bea4

I hope that helps.

Jørgen Holmefjord — Fri, 22 Mar 2019 13:52:52 GMT

Unfortunately, I'm not able to read the sniffer trace as it is encrypted. Please make sure you run the sniffer before commissioning the device into the network, for the sniffer to obtain the keys. This could require you to erase the devices before starting the commissioning procedure on the devices again.

RE: Zigbee Light Demo stops responding

IanAber — Fri, 15 Mar 2019 15:35:04 GMT

I had to download the Wireshark source and recompile it to get it to run on the Mac with the nRf52840 dongle, sorry for the delay.

I don't see where to add an attachment so the sniffer file is on my WEB site at www.cedartechnology.com/.../nRF52840DK.pcapng

The nRF52840DK is running the sample light bulb application. It was started just after the trace was begun. The device has address 0x10ad. The hub (address 0x0000) is a SmartThings V2 hub and has the nRF52840 listed as a light bulb. I am able to turn the light on and off via the SmartThings application on an iPhone.

Looking at the trace the last Link Status broadcast from the nRF52840 is at entry number 29229 followed by a couple of Route Reply messages which I assume are in response to the broadcast Route Request messages from the devices that are being replied to.

After this the nRF52840DK became unresponsive as can be seen starting at row 31914 where the SmartThings hub sent the Off command to turn off the light. This was not acknowledged. The hub repeated the command several times but no acknowledgements were sent by the nRF52840.

I do not see problems when the nRF52840 is in its own little network with the sample coordinator and switch only when in the full environment with the Samsung SmartThings controlled network.

Thanks very much for looking into this. If I can supply any further information please let me know. I can be reach by phone at +1-352-281-6286

Jørgen Holmefjord — Fri, 08 Mar 2019 15:18:31 GMT

Did you add the keys described in the sniffer documentation to Wireshark?

I need to forward the logs to the developers, I'm not able to decode it myself. I realized it would give the developers more details if I also included a sniffer trace with the logs.

RE: Zigbee Light Demo stops responding

IanAber — Fri, 08 Mar 2019 15:12:20 GMT

Despite spending many hours trolling through articles on the WEB I have so far been unable to generate a sniffer trace with Wireshark and the sniffer application available for the nRF52840 dongle. I can get a trace of data but as far as working out how to handle the encryption I have been entirely unsuccessful. If you can point me to some article that explains how to set this up for someone who does not have a PHD in encryption and wireless sniffing I would be very happy to get a trace to you and would be eternally grateful for the help. I would also hope that this might allow me to identify exactly what is going on myself and be able to feed you much more detailed information about what is might be causing it.

From the ZB log trace I provided and the very limited interpretation of the debug data I found does it look to you like there is a real issue here or am I misinterpreting the results? The fact that the code appears to be stuck in an endless loop called zb_nrf52840_abort with the parent function being zb_buf_from_ref led me to believe that the reference to the buffer is somehow invalid and the ZBoss has effectively panicked and shut down. Is this correct? It seems odd that it would stuff the device into what looks like a shutdown state from which there appears to be no way to recover other than pressing the reset button or cycling the power supply. In an embedded system I would expect the device to at least reboot after a period of time if not immediately The loop seems to be trying to ensure all the debug log data has been sent out but doesn't seem to do anything after that and I didn't find anything relevant in the debug console window to indicate that there was a problem anyway. Perhaps there is some watchdog function that could be set up to do this that would still respond to a time interrupt even though the main thread is stuck in a loop. Did I miss this? Is it just not built into the demo code?

I really do appreciate your help here. I am not sure what the situation is in Europe and Asia but in the US I believe that Samsung Smartthings is one of the main SmartHome ecosystems on the market available on shelves in stores all round the country and consequently any product aimed at this arena MUST be able to work flawlessly with it to stand any real chance of wide acceptance.

I know that debugging this sort of thing using just data from afar and not being able to recreate the problem in your own environment is a monumental task and I take my hat off too you for trying to help me here. Many thanks.

RE: Zigbee Light Demo stops responding

Jørgen Holmefjord — Fri, 08 Mar 2019 14:42:32 GMT

Could you also provide a sniffer trace, to see what is happening on-air between the devices?

RE: Zigbee Light Demo stops responding

IanAber — Thu, 28 Feb 2019 14:36:45 GMT

I have enabled the debug trace dump and run the program on the nRF52840DK. I put a breakpoint at the flush statement in zb_nrf52840_abort.

void zb_nrf52840_abort(void)
{
  while(1)
  {
#ifdef ZB_NRF_TRACE
    /* Flush all remaining logs, including reason of abort. */
breakpoint here ===>    zb_osif_serial_flush();
#endif /* ZB_NRF_TRACE */
  }

When the program stopped in the debugger I captured the debug window trace and it is pasted here. The stack trace shows that the abort was called from zb_buf_from_ref.

RE: Zigbee Light Demo stops responding

Can you enable the debug trace dump in your application, and provide the log from the crashing device?

RE: Zigbee Light Demo stops responding

It is beginning to look like this is something to do with the environment. I have only seen it happen when paired with the SmartThings hub and am in the process now of trying to pair it with a different hub. I suspect it is the light bulb not handling some message being sent by the hub. In the end it is a ZBoss problem as every other device I have works fine in this environment and the example code for the light bulb is not actually being call by the stack so the failure must be in the stack itself somewhere. I am looking for some way to trace what is going on but have, as yet, not found any way to do so.

Are you only seeing this issue when it is connected to the SmartThings hub? I have tested the application with light_switch and light_coordinator examples for some hours now, without seeing any issues.

I have uploaded the complete Segger project to my WEB site. You can get it at http://www.cedartechnology.com/Nordic/light_bulb.zip.

I joined the device to a network coordinated by a Samsung SmartThings hub which is running on channel 14. To make it easier I simply set the channel to 'All Channels' in main.c so when the board goes into discovery it will search for any coordinator in join mode. I also made the application clear the configuration if the ON button is pressed on startup.

Thanks for your help.
