RE: nRF52840 NCP become leader and stop receiving from old network

This issue should be fixed in new OpenThread libraries in upcoming SDK for Thread release. Please test with the new libraries as soon as the SDK is released. If you want to request more details on when the SDK will be released, please contact your regional sales manager.

Our developers are trying to reproduce this issue internally. We will get back to you with an answer as soon as possible.

Hello Lukasz,

I rebuild the openthread NCP code based on the latest version on git (commit c87a81d), and follow the instruction on the infocenter link. Unfortunatly, I couldn't find the folders for step 5 for the USB connectivity, so I skipped them, and it doesn't seem to make any issue.

So once more i launch my app and after some time another issue rose : "SpinelNCPInstance-Protothreads.cpp:228: Requirement Failed (Timed out while waiting 5 seconds for empty outbound buffer)", followed by "NCP is misbehaving or unresponsive" and then "State change: "associated" -> "uninitialized"", and a failing attempt to reset. I upload the syslog and getprop, check out the device02.syslog file. I have no sniffer data, but my app network log (so above the wpantund network interface) tell me that device01 and 03 stop receiving from device02 at 09:26:36.

Best,

Virgile

Hello vneu,

We are still investigate similar bug that you have found, however, based on your logs, device 2 has no free buffers and all of them are placed in 6Lo layer queue.

I have fixed that bug already: https://github.com/openthread/openthread/commit/082481864686abebab7b0f04790200f872b92bb3

Would it be possible for you to rebuild OpenThread libraries from the master branch and try to run your examples again?

I guess the best way would be to build them under Linux OS, since there were several changes in the OpenThread files.

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.thread_zigbee.v1.0.0%2Fthread_intro.html&cp=4_2_0_1_0_4&anchor=thread_qsg_libraries

We are sorry for inconvinience, the new libraries with proper fixes will be included in the subsequent releases of nRF5 SDK for Thread.

Here is an archive of the latest experiment that failed, this time it is the device 01 that failed (it was a router). There is the output of the commands for each devices and a capture performed using pyspinel on another PC. Device01 address is 0xcc00 and its last message is at packet 319922 (15:53:52.525670). Hope it helps.

It is the sending that fails first, the buggy devices still receives messages until 15:53:57.677357 (that is around packet 320101), and the syslog indicate that it went from router to leader at 15:56:45 :

You can provide the output of the commands regardless of if the issue have ocurred or not, it should give static information.

Yes, the buffer size is of interest to consider memory leaks, etc. If you could provide sniffer logs, please attach it and I will forward it to the developers in case it could be useful

Hi,

Thank you for the quick update, unfortunately I restarted it in an attempt to have more information, now I have to wait for it to crash again, I will keep you updated as soon as it happens.

In the mean time, it seems you think it is related to some kind of buffer being filled or overflowed, is that correct ? My application indeed sends quiet a lot of messages (around 70 packets/s) but stays under the ~200 kb/s (closer to 40-50 kb/s). These information have been measured with the pyspinel sniffer following this procedure : http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.threadsdk.v0.11.0%2Fthread_sniffer.html, if this can be useful for the developers.

Best,

Virgile

RE: nRF52840 NCP become leader and stop receiving from old network

Jørgen Holmefjord — Wed, 13 Jun 2018 08:56:13 GMT

Hi,

Our developers have been able to reproduce this behavior and are investigating this issue.

Could you run the following commands on your border router(s), and post the output in this thread?

wpanctl getprop
wpanctl getprop OpenThread:MsgBufferCounters:AsString

Best regards,
Jørgen
