DF beacon/scanner aging test crashes

choehyunho

Hi teams,

I am testing Direction Finding beacon/scanner pairs with nRF52833 DKs.

With nRFConnect SDK v1.7.1, I started beacon/scanner pair and leave untouched for a few days.

And I got the following crash in scanner side.

Any ideas?

P.S.> I have been testing this since it is available (v1.6.0, maybe), and has similar crashes in all tests.

    OK, now it is running as before.

    I'll leave additional notes if something happens.

    During longivity test, the following crash happens.

    It seems to be similar to the original crash. Please check.

    Can you follow the case there for progress?

    OK, I'll monitor that issue, too.

  • +1 in reply to Kenneth

    After I upgraded to nRFConnect SDK v1.8.0, regression test for more than a week does not show the same error above.

    Since the issue seems to be solved, I will close this.
