Dear Nordic Support Team,
I am currently performing Matter certification testing on our device based on the nRF54L15 using NCS v3.1.1 (Matter SDK 1.4.2). I am using the Matter Test Harness (v2.14+fall2025).
I have encountered several persistent failures during the "Mandatories" test suite run. Despite verifying our PICS and configuration, these tests continue to fail.
Below is a summary of the key failures and the specific error messages observed in the logs:
1. Device Type & Data Model Validation (TC-IDM-10.5)
Error: Invalid device type ID (out of valid range) But I just have a custom device type in endpoint 5 and I am testing the endpoint 0 now.
2. Access Control & Privileges (TC-ACE-2.3)
3. other failures:
TC-CADMIN-1.22 / 1.25.
TC-CCTRL-2.2 / 2.3.
TC-CGEN-2.2.
TC-CNET-4.10 / 4.12 / 4.16
TC-DA-1.2
How to analyze and solve them? Should I upload more information like PICS files ?
Environment Details:
Chip: nRF54L15
SDK: NCS v3.1.1
Matter Version: 1.4.2
Test Harness: v2.14+fall2025
Transport: BLE + Thread
Here is the total logs.
