RE: Smoke CO interconnect attribute example in nrf54l15

Hi,

I just got a reply from the team now.

We don't enable the interconnect attribute in our SmokeCO sample, and this needs to be enabled by the developer using the sample (you).

From the core spec

Based on the specification of Smoke CO Alarm, the device should somehow get the information from branched device about CO alarm/Smoke Alarm and update the attributes' value.

The Command which was run by you is the Test Event Trigger, which may return the fault due this attribute being enabled.

I'm not sure if this is helpful, but to me it might imply that the attribute is not set up properly.

Additionally, See the return False in last line (line 9) of the handling test event trigger call, which should be replaced by break similarly as it is done for other test event trigger handling e.g.

Kind regards,
Andreas
