ICD UserActiveModeTrigger causes a crash

[Tom McGuinness]

I have an ICD configured Matter device, using LIT.

I have added the UserActiveModeTrigger attribute and configured it to PowerCycle and ResetButton.

I can commission the device without issue and I can see a message on the controller side indicating that the ICD record is stored with a check-in identifier.

Using the Smoke Alarm sample, I copied in this code into a Button callback.

#ifdef CONFIG_CHIP_ICD_UAT_SUPPORT
	LOG_INF("ICD UserActiveMode has been triggered.");
	Server::GetInstance().GetICDManager().OnNetworkActivity();
#endif

Clicking the button results in a crash.

Any idea what could be wrong?

Hi Tomas,

Could you show me what configs you've enabled in this project?

I have these, which I think are the relevant ones

# Enabling low power
CONFIG_PM_DEVICE=y

# Switch Minimal Thread Device on
CONFIG_OPENTHREAD_MTD=y
CONFIG_OPENTHREAD_NORDIC_LIBRARY_MTD=y

# Set Matter as Intermittant Connected Device
CONFIG_CHIP_ENABLE_ICD_SUPPORT=y
CONFIG_CHIP_ICD_LIT_SUPPORT=y
CONFIG_CHIP_ICD_REPORT_ON_ACTIVE_MODE=y

# More power saving.
CONFIG_RAM_POWER_DOWN_LIBRARY=y

Any update on this for me?

Thanks for the patience. We could check what the failing instruction set is, but this could also be a simple timing issue; you shouldn't do too much in a callback. Could you try doing this in a workqueue instead? For more on how to set that up, see here.

I agree that this looks like all the relevant ones. What NCS version are you using?
