Matter 4.3.1.8. Device Type (DT) TXT key

[H-ogawa]

Hi,

This function is optional, but what if I want to turn it on on the DUT side?

Best regards,

Hi Hiroki,

As far as I know, you can enable them during testing using the CHIP tool: https://docs.nordicsemi.com/bundle/ncs-latest/page/matter/chip_tool_guide.html#using_chip_tool_for_matter_device_testing. 

In case you've not seen this documentation page, have you found anything seen the creating a Matter end product page documentation https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/end_product/index.html 

Kind regards,
Andreas

Hi, Andreas

Thank you for reply.

I checked the URL and it is a document on how to use the chip-tool. I would like you to tell me in detail which part is actually related to Matter 4.3.1.8. Device Type (DT) TXT key.

This is also the same. Could you please tell me in detail where in the documentation the Matter 4.3.1.8. Device Type (DT) TXT key is?

Best regards,

Just to add a bit more:
The reason we want to check is that we need to check that the following is valid in Base.xml of the PICS Tool in the Matter Certification tool.

I believe this is something that is enabled/disabled on the DUT side.

I'm not sure if I follow your request. Running clusters in test is here https://docs.nordicsemi.com/bundle/ncs-latest/page/matter/chip_tool_guide.html#running_testclusters_test.

Could you enlighten me some more? Am I misunderstanding what the optional function is and how you want to test it?

Kind regards,
Andreas

Hi,Andreas

I'm not sure I answered the question correctly either, so I'll ask it again.

I am conducting the TC-DD-2.1 test cases in the Matter certification exam.

I cannot determine whether the test in step 13b of that test case can be tested as a device or not.
In fact, when I test with the v2.9.0 lock sample code, the Device Type value is not visible as TH.
I would like to confirm whether I need to change the settings in the lock sample code to make this visible.

In the Lock sample code, the vendor ID and product ID in step 13a of the test case were confirmed in TH.

Best regards,

Hiroki

Hi Hiroki,

Just a status update to let you know I'm waiting for some input from the Matter team.

Thank you for your patience

Kind regards,

Hi again Hiroki

I got some input from R&D. Since the Device Type TXT Key is not something that the sample supports out of the box, you will have to add support for this in the application before testing it in the TH. You only need to change MCORE.DD.TXT_KEY_DT to true in the Base.xml PICS file used to certification.

Let me know if this works and I'll get back to you

Kind regards,
Andreas

I would like to know how to add this or set it in my application.

I believe this PICS setting is at the discretion of the certification body to decide whether or not to perform certification testing. I do not believe that simply enabling this setting will change the settings of the device being tested.
