Hi Sam, The code you showed in the question is the proper fix. checking p_addr against NULL. I have created a bug and I just checked that it has been fixed by the team end of March. I think it should have been released with 8.1, but i did not check that myself

Hi Sam,

Thanks for reporting this issue

the function where this problem occurs device_instance_find is used at two places.

when we have get a BLE_GAP_EVT_CONNECTED event and
when we get BLE_GAP_EVT_SEC_INFO_REQUEST event

when the latter occurs the the p_addr is NULL as we try to find the instance using evt.gap_evt.params.sec_info_request.div That check for p_addr which you have added to fix this issue is a proper way to fix this issue. This is a bug which I have reported to the team. Hopefully it will be fixed in next release.
