Unable to Commission nRF5340DK Matter Light Bulb Example Using NCS 3.1.0 and chip-tool 3.1.0

Hi Vishal,

Apologies for the lack of follow up and thank you for your patience and update.

I will make an internal epic of this case to investigate if this is a bug since you state that it worked fine in NCS 2.9.1

Kind regards,
Andreas

FYI switching back to sdk 2.9.1 instead of 3.1.0 fixed the issue

Thanks,
Vishal Gade.

Hi Andreas,

Thank you very much for the detailed pointers and tips. I have tried regenerating consistent DAC/PAI bundles, ensured correct VID/PID in certs, performed full chip erases, reflashed with new factory data. However, I still cannot successfully commission the device using chip-tool 3.1.0 with the Nordic nRF5340DK Matter light bulb example on NCS 3.1.0.

I also tried commissioning the same device using a Google Nest Hub as the commissioner but encountered a similar failure with device attestation errors and failure to advertise the commissionable node. This makes me suspect that the issue might be related to the Nordic sample firmware on the nRF5340 itself, particularly its inability to advertise the commissionable node over Thread (error code 3).

Could you please advise if this issue could be caused by a hardware problem or if it might be related to a bug or limitation in the Nordic SDK 3.1.0 version?

For reference, below is the relevant part of the log during boot and commissioning attempts showing the advertising failure and attestation issues:

bootup log on nrf5340 sdk no changes to the sample code

RE: Unable to Commission nRF5340DK Matter Light Bulb Example Using NCS 3.1.0 and chip-tool 3.1.0

Hi Vishal,

As you say there are issues with the attestation (The chip-tool and firmware produce commissioning failures, including device attestation errors and continuous failures to advertise the commissionable node over Thread (error code 3).)

Typically this is induced whentheres a mismatch with the key that's been used to sign the attestation elements and the DAC key. It could be caused by

Mismatched factory data: DAC certificate & private key don’t belong together (this is what I belive is the case issue at least)
Corrupted/incorrect factory-data partition.
You flashed new certs but the old key is still in NVS/factory area.
Using a custom/test PAA/PAI chain but the runtime key the device uses to sign isn’t the DAC key.

Here's a couple of pointers and tips that may resolve it

Regenerate a consistent DAC/PAI bundle:
- Generate PAA → PAI → DAC and the matching DAC private key using the same tool run.
- Make sure VID/PID in certs match your build (your log shows VID 0xFFF1, PID 0x8005).
Provision the factory data correctly on the DK:
- Enable factory data in your app Kconfig (typical options):
  - CONFIG_CHIP_FACTORY_DATA=y
  - Provide a factory_data.hex/bin that includes DAC cert, DAC key, PAI cert, CD (Certification Declaration), etc.
- Or, for quick sanity check, build with Nordic’s fixed example credentials option (commonly CONFIG_CHIP_DEVICE_FIXED_DAC_CREDENTIALS=y) to confirm the flow works; then switch back to your own factory data.
Erase stale data before reflashing:
- Full chip erase (both cores) or at least erase the factory-data/NVS partitions so old keys aren’t lingering.
- Reflash: application + network core + new factory-data image.
(If you use a non-default PAA) make sure the commissioner trusts it:
- If you created your own PAA, either add it to chip-tool’s trust store or point chip-tool to it (otherwise you’d usually see a different error like “no trusted root,” but it’s worth ensuring).
Recommission cleanly:
- Put the device back into commissioning mode (hold buttons per the sample; or reset + long-press to start BLE adv).
- Clear controller state on the host only if needed: delete /tmp/chip_* files to avoid stale fabrics, then run pairing again:
  - Thread example: ./chip-tool pairing ble-thread 1 <dataset-hex> 20202021 3840
  - Or setup code: ./chip-tool pairing code 1 <code>
