direction_finding_connectionless_rx crashes if CONFIG_ASSERT=y

[jakkra]

If I enable CONFIG_ASSERT=y this example will crash (or code using the DF APIs)

To reproduce:

- nRF Connect 1.6.1

- In direction_finding_connectionless_rx add CONFIG_ASSERT=y to the prj.conf

- Build direction_finding_connectionless_rx and direction_finding_connectionless_tx

- Flash and run, then you will see the log below on the device running direction_finding_connectionless_rx

Log from the example:

Enable receiving of CTE...
success. CTE receive enabled.
Scan disable...Success.
Waiting for periodic sync lost...

Hi

I tried this on my end and did not run into an assertion fail like this. Are you running the RX and TX examle projects on nRF52833 DKs or custom boards? Is the RX device connected to an antenna array or is it just using a single antenna?

Best regards,

Simon

I now have both TX and RX (without antenna array) running on two nRF52833-DK and I get the same issue, only modification I made is to add the  CONFIG_ASSERT=y in receiver prj.conf

Here is a full log on RX side. Could it be the issue is that there are many devices around here which causes the problem. I can give it a try in a shielded box to verify that as that could explain why you are not able to reproduce.
