Hello.
Are you able to give any specific details around an SDC Assertion with File ID 13 and Line 451 please?
The nRF Connect version is v3.2.4.
I'm trying to isolate if this was likely to be a timing fault, but tracing so far has suggested this isn't likely to be a problem.
Hi again Hayden
Sorry for any confusion.
Over the weekend we have gotten a good understanding of this bug, and luckily the fix isn't too complicated either. We aim to merge the fix to the main branch of the nRF Connect SDK this week, and include it as a part of the NCS 3.4.0 release.
If you require a fix in the current NCS version, let me know and we'll see what we can do on that note.
Best regards,
Simon
This is great news, thanks Simon.
If you can provide a patch for the current NCS version, that'd be helpful.
To keep this thread updated:
Having applied the patch, we're seeing bt_hci_cmd_send_sync never complete.
I'm still trying to gather more information.
Simon D-M : Can you confirm if this patch is included in the new nRF Connect v3.3.0 release?
Hi,
My guess is that it has not been pushed to version 3.3.0. From what I understand it will be included in v3.4.0, but not v3.3.x.
However, I'm not 100% sure. So, I've also forwarded the question internally. I'll get back to you tomorrow to confirm it.
Best regards,
Simon D-M
Thanks Simon D-M .

Hi,
First can you elaborate a bit on:
Hayden Ball said:Having applied the patch, we're seeing bt_hci_cmd_send_sync never complete.
We don't really understand what you meant by that. bt_hci_cmd_send_sync is a generic Zephyr Host function used for sending a lot of HCI commands from the Host to the Controller. Then it is waiting for a command complete from the controller.
Does bt_hci_cmd_send_sync fail for all commands, or is there a specific one that doesn't work?

I was correct, it has not been merged to any branch/version yet (not even main)
Hayden Ball said:Are you able to provide a new SDC patch for nRF Connect v3.3.0, please?
Are you asking about the patch same we sent you before or a different patch that would fix the bt_hci_cmd_send_sync issue?
If you are asking about the second option, we tested the already provided patch in a sample where we were able to reproduce the issue. And it passed all our regular CI tests. So it would be weird if that caused the bt_hci_cmd_send_sync issue.
We can't fix a bug we can't reproduce. Please give more information on how to reproduce this bug.
Best regards,
Simon D-M
