Unusual Wi-Fi behavior with net_sock and net_mgmt requests

RE: Unusual Wi-Fi behavior with net_sock and net_mgmt requests

Hello,

I apologize for the delay. Our codebase is very large, and bundling it to run on the nRF7002DK was quite tedious. However, we were able to recreate the bug with the code that I will attach to this message. It took some time for the bug to appear, but we eventually managed to replicate it. I will also include an example of the logs we extracted during the test, which might be helpful.

Even though the code is small, it can be a bit dense to understand. We apologize for that. To give you the most faithful representation of our real code, we had to import our general algorithm. This might seem unnecessary in this context, as it doesn't contain the entirety of the code, but we hope it doesn't cause too much confusion.

We greatly appreciate your support. Please feel free to reach out if you notice anything odd or have any questions. Thank you very much, and have a great day.

Ok, have you done any test on nRF7002DK? Could you share your testing codes?

I can try to test your codes with nRF7002DK to see if I can repeat this issue.

Hello,

We are reaching out to you again as we had the opportunity to create a test environment with your criteria that was running during this weekend. Unfortunately, even without step 3, the bug happened again about 10 hours after the start of the test. We launched another test on another card on the same AP at the same time, with the only difference being that instead of connecting every 5 minutes, it connected every hour. This test ran smoothly without any bugs or issues.

As for trying to launch with a debugger, we could not do that as we are conducting very long tests and cannot be there to catch the error in real time. We are sorry for that.

We hope this bit of information could help you assist us. Thank you for your time and have a great day.

Hi Benjamin,

Thanks for checking with us about this issue. As you mentioned, memory leaking is highly suspect.

For the next steps, there are two things worth to try:

1. Can you test without step 3 and comment related codes about this step? This will help to confirm the issue is actually caused by Wi-Fi.

2. Could you try to change to another AP or just reset AP when this issue happens?

Additional debugging information can be collect by following this document page: Debugging — nRF Connect SDK 2.6.1 documentation (nordicsemi.com)

Best regards,

Charlie
