Zigbee Light Demo stops responding

[IanAber]

I programmed a NRF52840 Dongle with the example light switch code having changed the channel to 14 which is what my coordinator is on.

I then programmed a NRF52840DK with the example switch code and adjusted the search to look specifically for the dongle with the endpoint at 10. All the other compatible devices in my Zigbee network have endpoints set to 1.

I programmed my Smartthings hub to recognise the Nordic dongle as a simple light bulb.

I put the hub in discover mode and fire up the dongle and the DK which both connect.

The Smartthings hub recognises the dongle as a light and I can turn it on and off from the Smartthings app on my phone.

The NRF52840DK switch also finds the dongle and I can control the light on the dongle using the two buttons on the DK board. The Smartthings hub DOES NOT see the updates to the dongle made from the DK switch unless I manually refresh it, but that is another issue.

Everything is fine for a random amount of time varying between a few minutes and several hours up to just over a day on one occasion. Then the light (dongle) simply stops responding. It no longer responds to the Smartthings hub nor to the DK board switch. If I restart the switch it fails to find the light. Only when I restart the light does it work again.

Does anyone have any idea why this should be happening? Can anyone suggest how I can debug this situation?

[IanAber]

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.

[Jørgen Holmefjord]

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

[IanAber]

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.

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

[IanAber]

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.
