Out of memory (CHIP error 0x0b) when trying to commission Window Covering sample with GHA

[abollaert]

Hi,

I've been playing around with the Matter samples (in particular the window covering sample) to get them to work with the recently released Google Home Matter program.

I've gotten the lighting app example to work, but when I try to commission the window covering example I run into memory issues:

E: 201315 [DMG]Error retrieving data from clusterId: 0x0000_0031, err = b
E: 201613 [DMG]Error retrieving data from clusterId: 0x0000_0035, err = b

I already decreased log levels and disabled the shell, openthread shell, and the other optimization options as suggested in https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/app_memory.html, but I'm still getting OOMs.

Is there anything I'm missing here?

Kind regards and thanks

-Alex

Did a bit more digging, and I don't think the memory error is the cause for the commissioning failure.

The commissioning succeeds (in that it gets added to my devices in google home), but interaction with the device always fails with an error "operation discovery failed: 32". In Google Home the device gets marked as "unavailable".

For reference, my setup is an nRF52840 devkit for the sample, a Google Nest Hub 2 as the border router, commissioner and controller.

Kind regards,
