Matter Demo - Instructions to get the discriminator code - missing a command?

[HeneryH]

Step 5 of the Matter instructions at developer.nordicsemi.com/.../python_chip_controller_building.html

Shows getting the discriminator data.  What is shown looks like the output of some command that was entered via the shell command.

I do have access to the Zephry shell on the matter light switch demo client and I do see output to the shell showing Matter is running with some of the "I:" and "D:" output lines but I don't see how to get it to spit out the diagnostic data that is shown in step 5.

Am I missing something?  How to get that output?

Step 5: Commission the Matter accessory device over Bluetooth LE

The controller uses a 12-bit value called discriminator to discern between multiple commissionable device advertisements, as well as a 27-bit setup PIN code to authenticate the device. You can find these values in the logging terminal of the device (for example, UART). For example:

I: 254 [DL]Device Configuration:
I: 257 [DL] Serial Number: TEST_SN
I: 260 [DL] Vendor Id: 9050 (0x235A)
I: 263 [DL] Product Id: 20043 (0x4E4B)
I: 267 [DL] Hardware Version: 1
I: 270 [DL] Setup Pin Code: 20202021
I: 273 [DL] Setup Discriminator: 3840 (0xF00)
I: 278 [DL] Manufacturing Date: (not set)
I: 281 [DL] Device Type: 65535 (0xFFFF)

Hi,

Most likely you are not able to get the commissioning data from the shell because of the reason mentioned in the "Test mode" section in the sample documentation for the Matter Light Switch:

"Unlike other samples, such as Matter door lock, this sample does not support Matter commissioning over Bluetooth LE. To enable communication between the light switch and the light bulb devices, they must be initialized with the same static Thread network parameters and static Matter cryptographic keys."

I tested the Matter door lock sample, and there I can get the output from the onboardingcodes command.

Best regards,
Jørgen

Thank you.  I did notice on the benchtop lab I have that the light bulb sample did print out the commissioning data but the light switch did not.

I must have missed that note.

I'll try the lock demo too.

Thank you.
